७ टिप्स फोटो landscape

Tip 1: Bring a Tripod

Always bring a tripod if you plan on shooting landscapes. Even if the day is sunny, you may need to use a small aperture to achieve a great depth of field. In such cases, you may be using a low shutter speed – which leads to camera shake if you can’t hold the camera stable in your hands. Hence the need for a tripod. If you need a good travel tripod, I recommend the Vanguard Tourist-2 – I’ve used it for years and it functions very well.

Tip 2: Cable Release

One good tip is to carry a cable release. Instead of using the timer function on the camera, use the cable release. This ensures that you can trigger the shutter at precisely the right timing. In turn, this leads to reduced camera shake and a more beautiful photo.

Tip 3: Use the Right Filters

Filters are important when taking landscape photos. There are different types of filters that I use – polarizers, neutral density filters and graduated neutral density filters.

Polarizers are useful for reducing glare from water and other reflective surfaces. These create a more well-balanced and beautiful picture.

Neutral density filters will stop a specified amount of light entering the camera. I tend to use these for shooting waterfalls on a sunny day.

Graduated neutral density filters are a slight variation of this – they are dark on top and clear on the bottom, creating a ‘gradual transition’ from the dark to clear area. These filters are good for blocking out bright parts of a scene (say the sky) to create a more evenly exposed picture.

Tip 4: Research the Landscape

One thing to do before taking landscape photos is to do some background research on the landscape. If you’re taking pictures of the Nigara Falls, or the Grand Canyon, try to do some background study on what the most scenic spots are.

It’s also good to check out the weather conditions of the place. Check up the papers – if the weather doesn’t look good, you may want to try shooting another day.

Tip 5: Lenses

For shooting landscape photos, it’s usually best to bring wide-angle lenses. I also bring along a telephoto lens in case I want to shot some creative, zoomed-in shots.

Tip 6: Composition

Another thing to remember is that composition rules are still important in landscape photos. Make sure you have something in the foreground, mid-ground and background.

Tip 7: Shoot at the Right Time

For landscape photography, one thing I realize is that you should avoid shooting during mid-day. There is a lot of harsh lighting and bad shadow effects during that period. Early morning or late afternoon tends to be best.

CHECK LIST OVERVIEW - DIGITAL CAMERAS
E-mail Print PDF

i just read Digital Photography in Available Light written by mark galer.
and maybe can useful for other who want to find a "best" camera.

Q. How many pixels do I need - how big do I want to print?
A. 6 megapixels for a full page and 10–12 for a double page.

Q. Do I need to shoot RAW files in rapid succession?
A. Investigate the buffer size and speed of DSLR cameras.
B. not sure we need a rapid shutter click for landscape photography. but maybe if you interest in wildlife photography too you will need it much.

Q. Do I need to shoot hand-held in low light with raised ISO?
A. Choose a camera with a larger sensor, wide aperture lens and/or image stabilization and
check out whether the budget DSLR comes with an option of upgrading to a better lens,
brighter and with less barrel distortion at the wide-angle end of the zoom range.
B. use tripod !! or find any alternative to put the camera in stabel posisition,it's better idea :D

Q. Would I prefer to work with a live preview or with an optical viewfinder?
A. Check out cameras with 2.5-inch LCD displays and the Konica Minolta EVF before you
reach a decision on this one.
B. now, almost new dlsr have life view LCD. and yes it's very useful (for me).
I can check my LCD display when i put my camera in the tripod, zoom it until 10x to make sure that the object focus and sharp.

Q. Do I want or need movie capture, 3:2 format capture?
A. Only prosumer digicams offer movie capture and only a select few cameras offer the 3:2
format (some surprises in the prosumer digicam range).
B. with the new technology, capture HD movie now more easier.
even entry level dslr like canon 500D now can be use to capture HD movie.

Q. Can I change the ISO, image format setting, self-timer and white balance without referring
to the manual or trawling through submenus?
A. Many cameras place all of the important settings within easy reach these days. Some
manufacturers still need to talk with the photographers who use their cameras.

Q. Does the camera and lens come with useful features such as PC sync terminals, a
threaded cable-release socket, protected LCD displays, lens-hood and twist-barrel zoom
control, dual memory card slots and fast USB2 or Firewire data transfer?
A. Grab as many as you can on a single system. An individual feature is easy to overlook
unless you are ticking them off a list.

Tips for Sharper photo
E-mail Print PDF

1. Hand holding
The way you hold a camera has a huge impact on the sharpness of your images. if you hold a camera incorrectly, unintended camera movement leads not only to blurred images, but also to a reduction of contrast and image brilliance.
To create a stable platform with your own body, hold the camera with both hands, support the camera body (not the lens) by cradling it in your left hand a grasp the camera and shutter release button with your right hand. Press your elbows firmly against your body and raise the camera close to your eye. If you're using a digital camera with an LCD, avoid holding the camera away from your body with your arms extended.
Gently depress the shutter release button halfway and maintain pressure to achieve and lock focus. When you are ready to take the image, fully depress the shutter release button.

2. Tripod + cable release + mirror lockup
A tripod provides a stable platform for your camera and is a key means for ensuring sharp photographs. A tripod delivers the ability to create sharp images if you are shooting under low light before dawn or in bright sunlight.
The advantage is that tripod minimizes the effects of handling the camera incorrectly or your own body movement.
Cable release
Small press of the shutter has a big effect especially if you take slower shutter speed. Another tool to minimize shakes when press the shutter is use cable release.
Mirror lockup
Some dslr have mirror lockup feature. This will reduce the vibration. The image in the viewfinder will be blackened, but the actual moment of exposure won’t be impacted by mirror movement
So if you want to make a sharp picture to print on larger media, this combination will sure make your picture sharp

3. Shutter speed consideration
The shutter speed used when shooting without a tripod plays a critical role in image sharpness. As a guideline, choose a minimum shutter speed that's the reciprocal of the focal length you're using. At an effective focal length of 100 mm, select a minimum shutter speed of 1/125 sec, for example. Be aware that some dslr have a magnification factor that will increase the effective focal length of a lenses, resulting in the need for an even faster shutter speed.
To maintain an acceptable shutter speed for handholding, you may need to increase the camera's ISO sensitivity. Although this increases the appearance of grain or noise. It can make the difference between a sharp image that you can use and a soft image that useless.

Shutter speed recommendation chart
28mm 1/30 sec
50mm 1/60 sec
85mm 1/25 sec
180mm 1/250 sec
400mm 1/500 sec

4. IS and VR
Some of today's lenses include technology that reduces the effects of camera motion on image sharpness, Canon Image Stabilizer (IS) and Nikon’s Vibration Reduction (VR). These technologies use electronics and hardware to counter the slight movements that result in a soft image. These lenses have grown in popularity among sports and wildlife photographers, and although not intended to totally eliminate the use of a tripod, they provide a viable alternative when a tripod isn’t practical or available
These technologies offer the ability to handhold your camera at shutter speeds much slower than would be typically allowable. For example, a 200mm focal length that would normally require a shutter speed of 1/250 sec, may produce decent results at a shutter speed as slow as 1/60 sec. This is an advantage when light is fading and a higher ISO may not be advantageous or possible

5. Continous shooting mode
Most assume that the only time to use a camera's continuous shooting mode is when they’re shooting fast action such as sports of wildlife. Actually, this mode can be used as a way to increase the sharpness of all your images.
With each depression of the shutter release button, there’s a small degree of vibration that may adversely affect the crispness of your images. It occurs for only a fraction of a second, but it may be enough to produce undesirable softness. The use of a continuous shooting mode allows you to shoot several image of the same subject in rapid succession. Although the first image is slightly blurred because of vibration, subsequent images often will be sharper. Even for static subjects, you’ll usually find one shot perfectly sharp among of group of softer images.

6. Confirming auto focus
Autofocus has afforded a wonderful convenience for photographers, its accuracy and responsiveness has improved the sharpness of many of our images. Particularly when photographing moving subjects, autofocus technology has made it possible to produce consistent results more often
It is important not to totally surrender focus to this advanced technology, however it’s still necessary to confirm n what part of the scene is being focused. Multi-sensor autofocus systems, although accurate a majority of the time, may select another part of the scene that you don’t want to emphasize. To ensure that your main subject is sharp, pay careful attention to the AF sensor indicators inside your camera viewfinder. If the sensor isn’t the one that your desire, set it manually.
When photographing moving subjects, begin tracking and focusing on your subject well before you actually release the shutter release button. This allows the camera to achieve focus before the critical moment you’ll want to capture it

7. Moderate aperture
The rule of thumb for the aperture that results in the best sharpness on any lens has been two stop smaller than the widest aperture. A 105 mm f/1.8 lens likely will produce its best images at a working aperture of f/5.6, for example

baru2222222222 rebel t2i/canon 550d

Menyebutnya sebagai "Mini 7D," memperkenalkan Canon Rebel T2i, dengan resolusi konsumen tertinggi SLR, dan SLR resolusi tertinggi di bawah $ 900, periode. The 7D association comes primarily from Canon's use of an 18-megapixel sensor that Canon say is essentially the same spec as the sensor in the 7D, the only difference being that the readout speed has been cut in half. Asosiasi 7D terutama berasal dari penggunaan Canon sebuah sensor 18-megapixel Canon mengatakan bahwa pada dasarnya spec sama dengan sensor di 7D, satu-satunya perbedaan adalah bahwa pembacaan kecepatan telah dipotong dua. From there, the Canon T2i shares more with the Rebel T1i than with the 7D. Dari sana, Canon T2i saham lebih dengan Pemberontak T1i dibandingkan dengan 7D. The major exception to that is the movie mode, which now offers full manual exposure, and supports 1080p at 24, 25, and 30 frames per second, while the T1i only did 1080p at 20 fps. Pengecualian utama yang modus film, yang sekarang menawarkan eksposur manual penuh, dan mendukung 1080p di 24, 25, dan 30 frame per detik, sedangkan T1i hanya melakukan 1080p di 20 fps.

Walkaround . Walkaround. From the front the silhouette of the Canon T2i is very similar to the T1i, but there are a few unusual differences. Dari depan siluet T2i Canon sangat mirip dengan T1i, tetapi ada beberapa perbedaan yang tidak biasa. Weight is 18.5 ounces (1.2 pounds; 525g) with the battery and a memory card, but without the lens. Bobot 18,5 ons (£ 1,2; 525g) dengan baterai dan kartu memori, tetapi tanpa lensa. With the lens, battery, and card the Rebel T2i weighs 26 ounces (1.6 pounds; 736g). Dengan lensa, baterai, dan kartu Pemberontak T2i berat 26 ons (1,6 £; 736g). The Canon T2i's dimensions are 5.1 x 3.8 x 3.0 inches (130 x 97 x 76mm), perhaps a little shorter and a little thicker than the T1i. dimensi yang T2i Canon adalah 5,1 x 3,8 x 3,0 inci (130 x 97 x 76mm), mungkin sedikit lebih pendek dan sedikit lebih tebal daripada T1i.

Immediate differences from the front include a new knurl on the Canon T2i's Mode dial, even more rubber grip area, slight nudges of the IR remote window and Self-timer lamp, and the combining of the nameplates into one, rather than two separate badges on the right side. perbedaan Segera dari depan termasuk bonjol baru pada dial Mode yang T2i Canon, bahkan lebih luas karet pegangan, dorongan kecil dari jendela IR remote dan lampu Self-timer, dan kombinasi dari nameplates menjadi satu, bukan dua lencana terpisah sisi kanan. New is the strangely contoured panel on the lower right in the above image, perhaps to reinforce and soften the area where your palm rests when you're controlling the Canon T2i's lens. Baru adalah panel anehnya berkontur di bagian kanan bawah pada gambar diatas, mungkin untuk memperkuat dan melunakkan daerah mana telapak tangan terletak ketika Anda mengontrol lensa Canon T2i. Nikon has for several years deliberately cut out this area to provide palm relief, so perhaps Canon is doing the same. Nikon telah selama beberapa tahun dengan sengaja memotong daerah ini untuk menyediakan bantuan sawit, jadi mungkin Canon adalah melakukan hal yang sama.

Very few differences appear on the top of the Canon T2i, except for a few contour changes to the body shell. Sangat sedikit perbedaan muncul di bagian atas T2i Canon, kecuali beberapa perubahan kontur kulit tubuh. The mode dial has a black background rather than a silver one, and as previously mentioned, now has fairly deep vertical grooves around its outside edge, rather than the shallower knurling of the T1i's dial. Tombol modus memiliki latar belakang hitam daripada perak satu, dan seperti yang disebutkan sebelumnya, sekarang memiliki alur vertikal yang cukup mendalam di tepi luarnya, bukan knurling dangkal dari dial T1i's. The order of the scene modes on the dial has also been changed, promoting the Flash Off mode to the top of the list, rather than the Portrait mode. Urutan adegan pada mode dial juga telah berubah, mempromosikan Flash Off mode untuk bagian atas daftar, bukan modus Potret. The Canon T2i's 18-55mm IS lens is unchanged. The T2i Canon 18-55mm IS lensa tidak berubah. It performs well for an inexpensive kit lens, but the Rebel T2i's 18-megapixel sensor demands superior optics to show its true potential. Ini berkinerja baik untuk lensa kit murah, tapi menuntut 18-megapiksel Rebel T2i's sensor optik superior untuk menunjukkan potensi yang sebenarnya.

Most of the retooling and rethinking can be found on the back of the Canon T2i. Sebagian besar memperbarui peralatan dan memikirkan kembali dapat ditemukan di bagian belakang T2i Canon. Though it's subtle, Canon's switch from a 4:3 screen to a 3:2 screen has a dramatic effect on where some of the controls land, and may contribute to the one millimeter reduction in the Canon T2i's height. Meskipun itu halus, Canon beralih dari layar ke layar 04:03 03:02 memiliki efek dramatis di mana beberapa kontrol tanah, dan dapat berperan dalam mengurangi milimeter satu di ketinggian T2i Canon.

Button design has changed quite a bit on the Canon T2i, moving from primarily circular buttons with nothing printed on them to larger shaped buttons, some with words and icons printed on them. Tombol desain telah berubah agak sedikit di T2i Canon, bergerak dari terutama tombol lingkaran dengan tidak tercetak pada mereka untuk tombol berbentuk lebih besar, sebagian dengan kata-kata dan ikon yang tercetak di atasnya. It does make the labels clearer, especially with reduced real estate for labels next to buttons because of the wide-aspect LCD. Itu membuat label lebih jelas, terutama dengan real estate dikurangi untuk label di sebelah tombol karena aspek LCD lebar. The variation in button shapes also makes them easier to identify without removing your eye from the viewfinder. Variasi dalam bentuk tombol juga membuat mereka lebih mudah untuk mengidentifikasi tanpa menghapus mata Anda dari jendela bidik. Live View / Movie Recording has a new button in prime position for easy thumb activation, just right of the optical viewfinder. Live View / Movie Perekaman memiliki tombol baru di posisi utama untuk aktivasi thumb mudah, hanya kanan jendela bidik optik. In its old place is the new Quick Menu button, an innovation borrowed from the Canon 7D. Di tempat yang lama adalah Quick Menu baru tombol, sebuah inovasi yang dipinjam dari Canon 7D. This allows easy adjustment to the Canon T2i's settings via the Status display, which transforms into a Quick Menu screen with a press of this button. Hal ini memungkinkan penyesuaian mudah untuk pengaturan T2i Canon melalui layar Status, yang berubah menjadi layar Menu Cepat dengan menekan tombol ini. (In Movie and Live View shooting, the same button calls up an abbreviated Quick Menu display that forms a column at the left of the LCD, rather than occupying the whole screen.) All other buttons are in the same positions relative to the T1i. (Dalam film dan Live View shooting, tombol yang sama atas sebuah layar panggilan cepat disingkat Menu yang membentuk kolom di sebelah kiri LCD, daripada menempati seluruh layar) Semua tombol lainnya berada di posisi yang sama relatif terhadap T1i.. The speaker holes on the rear, though, go from four holes to nine holes, presumably for better sound transmission. Pembicara lubang di bagian belakang, meskipun, pergi dari empat lubang ke sembilan lubang, mungkin untuk transmisi suara yang lebih baik.

Sensor and processor . Sensor dan prosesor. The Canon EOS T2i's design is based around a DIGIC 4 image processor and a newly developed CMOS image sensor that's very closely related to the chip previously seen in the EOS 7D. Desain Canon EOS T2i adalah berbasis di sekitar prosesor gambar DIGIC 4 dan sebuah sensor gambar CMOS yang baru dikembangkan yang sangat erat terkait dengan chip sebelumnya terlihat di EOS 7D. As with that camera, effective resolution is 18.0 megapixels -- a modest upgrade from the 15-megapixel imager of the T1i. Seperti halnya dengan kamera itu, resolusi efektif adalah 18,0 megapixels - upgrade sederhana dari imager 15-megapiksel dari T1i. Maximum image size in pixels is 5,184 x 3,456. Maksimum ukuran gambar dalam pixel adalah 5.184 x 3.456. Pixel pitch is 4.3µm, and gapless microlenses help boost light gathering capability. Pixel pitch adalah 4.3μm, dan gapless microlenses membantu meningkatkan kemampuan mengumpulkan cahaya.

Where the two imagers differ is in their readout method, and hence their speed. Dimana dua imagers berbeda adalah dalam metode pembacaan mereka, dan karenanya kecepatan mereka. The EOS 7D's sensor has eight channel readout, key to that camera's eight frames per second burst shooting. Sensor EOS 7D telah delapan pembacaan saluran, kunci untuk delapan bahwa kamera menembak burst frame per detik. The Canon Rebel T2i's sensor has four channel readout, which means a more modest 3.7 frames per second burst shooting -- but it's still a slight upgrade in speed from the 3.4 frames per second of the T1i. Sensor Canon Rebel T2i telah empat pembacaan saluran, yang berarti lebih sederhana 3,7 frame per detik penembakan meledak - tetapi masih sedikit di upgrade kecepatan dari 3,4 frame per detik dari T1i. Unfortunately, the increased throughput caused by the faster burst speed and higher sensor resolution together conspire to greatly reduce the burst shooting depth as compared to the T1i. Sayangnya, throughput meningkat disebabkan oleh pecah lebih cepat kecepatan dan sensor resolusi yang lebih tinggi bersama-sama bersekongkol untuk sangat mengurangi kedalaman meledak penembakan dibandingkan dengan T1i. According to Canon, the Rebel T2i can capture six RAW or 34 large/fine JPEG frames in a burst, where the T1i was capable of nine RAW or 170 large/fine JPEG frames before shooting slowed. Menurut Canon, Rebel T2i dapat menangkap enam RAW atau 34 besar / frame JPEG dengan baik dalam meledak, di mana T1i mampu sembilan RAW atau 170 besar / frame JPEG halus sebelum menembak melambat.

14-bit A/D conversion . 14-bit A / D konversi. Just like the XSi and T1i, the Canon T2i uses 14-bit Analog-to-Digital conversion when creating JPEGs, for smoother color transitions, and RAW files are saved as 14-bit files. Seperti XSi dan T1i, yang T2i Canon menggunakan 14-bit Analog-to-Digital konversi saat membuat file JPEG, untuk transisi warna halus, dan file RAW disimpan sebagai 14-bit file. Converting from 14-bits worth of data means that the saved images are theoretically formed from four times the color information that was available to the Canon XTi, which was only able to generate 4,096 colors per channel. Konversi dari 14-bit nilai data berarti bahwa gambar yang disimpan secara teoritis dibentuk dari empat kali informasi warna yang tersedia untuk Canon XTi, yang hanya mampu menghasilkan 4.096 warna per saluran. The Canon Rebel T2i can recognize 16,384 colors per channel, which should mean smoother tones and more accurate color overall. The Canon Rebel T2i dapat mengenali 16.384 warna per saluran, yang seharusnya berarti nada warna yang halus dan lebih akurat secara keseluruhan. Though JPEGs will still be saved as 8-bit color, RAW images will benefit more fully from the 14-bit depth, making for more accurate 16-bit images in programs like Photoshop. Meskipun file JPEG akan tetap disimpan sebagai 8-bit warna, gambar RAW akan mendapat manfaat penuh dari kedalaman 14-bit, sehingga untuk gambar 16-bit yang lebih akurat dalam program-program seperti Photoshop.

Peripheral illumination correction . Perangkat iluminasi koreksi. Brought over from the 50D, the Canon T2i's Peripheral illumination correction compensates for vignetting in the corners of a lens. Dibawa dari 50D, koreksi pencahayaan Perangkat yang T2i Canon mengkompensasi vignetting di sudut-sudut lensa. The amount of correction changes depending on which lens is mounted; selecting the Peripheral Illumination Correction item from Record Menu 1 brings up a screen where you can see which lens the camera has detected, and whether correction data is available. Jumlah koreksi perubahan tergantung pada lensa yang dipasang; memilih item Pencerahan Peripheral Koreksi dari Rekor Menu 1 menampilkan layar di mana Anda dapat melihat lensa kamera telah terdeteksi, dan apakah data koreksi tersedia. You can also either enable or disable the function from the same screen. Anda juga dapat baik mengaktifkan atau menonaktifkan fungsi dari layar yang sama.

Autofocus and metering . Autofocus dan metering. Another feature inherited from the EOS 7D is the Canon T2i's new metering sensor. Fitur lain yang diwarisi dari EOS 7D sensor metering baru T2i Canon. Where the T1i used a 35-zone metering sensor, the Canon T2i now includes a 63-zone iFCL sensor, which stands for Intelligent Focus, Color, and Luminance metering. Dimana T1i menggunakan sensor metering 35-zona, yang T2i Canon sekarang termasuk sensor iFCL 63 zona, yang singkatan dari Intelligent Fokus, Warna, dan metering Luminance. The name hints at how the sensor works: the iFCL chip has a dual-layer design with each layer sensitive to different wavelengths of light, allowing subject color to be taken into account when determining exposure. Nama petunjuk bagaimana sensor bekerja: chip iFCL memiliki desain dual-layer dengan setiap lapisan peka terhadap panjang gelombang cahaya yang berbeda, memungkinkan warna dikenakan diperhitungkan saat menentukan eksposur. Information on focusing points is also taken into account in metering calculations, and it is in this area that the Canon T2i's iFCL chip differs from that of the EOS 7D, accounting for fewer focus points in the consumer Rebel camera than its prosumer sibling. Informasi tentang titik fokus juga diperhitungkan dalam perhitungan metering, dan dalam bidang ini bahwa chip iFCL yang T2i Canon berbeda dengan EOS 7D, akuntansi untuk titik fokus lebih sedikit pada kamera Pemberontak konsumen dari saudara prosumer nya. Like the T1i before it, the Canon T2i offers nine-point focusing with a central cross-type f/2.8 focus point, rather than the 19-point AF of the 7D. Seperti T1i sebelum itu, T2i Canon menawarkan sembilan-titik fokus dengan titik silang-jenis pusat f/2.8 fokus, bukan AF 19-titik di 7D. The focusing screen, likewise, is of the etched variety, and not the fancy LCD overlay on the Canon 7D. Layar fokus, juga, adalah jenis tergores, dan bukan tampilan LCD mewah di Canon 7D.

ISO Expansion . ISO Ekspansi. The Canon T2i has the same expanded sensitivity range as that of the T1i and 7D, from a minimum of ISO 100 to a maximum of ISO 12,800. The T2i Canon memiliki rentang sensitivitas yang sama seperti yang diperluas dari T1i dan 7D, dari minimal ISO 100 sampai ISO maksimum 12.800. A very useful change inherited from the EOS 7D - particularly for fans of HDR shooting -- is the T2i's expanded exposure compensation range. Sebuah perubahan yang sangat berguna diwarisi dari EOS 7D - khususnya untuk para penggemar shooting HDR - diperluas pemaparan jajaran T2i kompensasi. Where the T1i offered compensation from -2.0 to +2.0 EV, the T2i has a much wider +/-5.0EV exposure compensation range. Dimana T1i ditawarkan kompensasi dari -2,0 ke 2,0 EV, yang T2i memiliki yang lebih luas + /-5.0EV rentang kompensasi eksposur.

Creative Auto mode . Kreatif Auto mode. First introduced on the Canon 50D, Canon's Creative Auto mode is also included in the Rebel T2i. Pertama diperkenalkan pada modus Canon 50D, Canon Auto Kreatif juga dimasukkan dalam Rebel T2i. Marked with a "CA" on the Mode dial, this mode is a cross between the Auto and Program modes. Ditandai dengan "CA" pada tombol Mode, mode ini merupakan lintas antara mode Auto dan Program. When set to CA mode, the Canon T2i allows the user to adjust the Flash, resolution, drive mode, and Picture Style. Jika diatur ke mode CA, yang T2i Canon memungkinkan pengguna untuk menyesuaikan Flash, resolusi, mode drive, dan Picture Style. Setting aperture and exposure are converted to easier concepts of background blur (blurred or sharp), and exposure level (darker or brighter) with a slider that's adjusted with the Main dial. Pengaturan aperture dan exposure yang lebih mudah dikonversi menjadi konsep latar belakang blur (kabur atau tajam), dan tingkat eksposur (gelap atau terang) dengan slider yang disesuaikan dengan dial Utama. The more complex exposure decisions remain under the Canon T2i's control in CA mode. Keputusan lebih kompleks eksposur tetap berada di bawah kontrol T2i Canon dalam mode CA. The exposure slider is the more useful, standing in as a more comprehensible EV adjustment. Slider eksposur adalah lebih berguna, berdiri di sebagai penyesuaian EV lebih dipahami.

Copyright info . Hak Cipta info. Like the Canon 7D, you can input Copyright information right on the Canon T2i, as well as delete it at will. Seperti Canon 7D, Anda dapat memasukkan Copyright informasi yang tepat pada T2i Canon, serta menghapusnya di akan. It was a first in that camera for Canon's prosumer line, and now it's on the consumer Rebel line as well. Ini adalah pertama dalam kamera yang untuk line prosumer Canon, dan sekarang pada baris Pemberontak konsumen juga.

LCD . LCD. The Canon T2i also features a new LCD panel, which now offers a 3:2 aspect ratio, matching that of the image sensor, rather than the 4:3 aspect ratio panel which was used on the T1i. The T2i Canon juga dilengkapi sebuah panel LCD baru, yang sekarang menawarkan rasio aspek 3:2, cocok bahwa dari sensor gambar, daripada panel aspek rasio 04:03 yang digunakan pada T1i. The new panel still has a 3.0-inch diagonal, but increases the total pixel count slightly from somewhere in the region of 640 x 480 pixels to a ~720 x 480 pixel array. Panel baru masih memiliki diagonal 3,0 inci, tetapi meningkatkan jumlah total pixel sedikit dari suatu tempat di wilayah 640 x 480 piksel ke piksel array ~ 720 x 480. Each pixel still consists of three separate colored dots (red, green and blue), for a total count of just under 1.04 million dots. Setiap pixel masih terdiri dari tiga titik berwarna yang terpisah (merah, hijau dan biru), dengan jumlah total hampir 1.040.000 titik. The Canon T2i's 160-degree LCD viewing angle isn't quite as wide as that of the 170 angle possible on the T1i, and the total display area is just slightly smaller, although neither reduction is terribly noticeable in use. 160 The Canon T2i derajat sudut pandang LCD tidak cukup selebar bahwa dari sudut 170 mungkin di T1i, dan luas total tampilan hanya sedikit lebih kecil, namun reduksi ini sangat terlihat tidak digunakan.

Improved Movie mode . Peningkatan Movie mode. Another area where the Canon EOS Rebel T2i has inherited significant upgrades from the 7D is in its high definition video capabilities. Bidang lain dimana Canon EOS Rebel T2i telah mewarisi upgrade signifikan dari 7D berada dalam kemampuan video definisi tinggi. The previous T1i model offered a maximum resolution of 1080p (1,920 x 1,080 pixels), but with a non-standard (and rather low) rate of 20 frames per second, making this mode perhaps of limited use. Model T1i sebelumnya menawarkan resolusi maksimum 1080p (1920 x 1080 piksel), tetapi dengan standar-non (dan agak rendah) tarif 20 frame per detik, sehingga mode ini mungkin penggunaan terbatas. Lower-resolution options of 720p (1,280 x 720 pixels) and VGA (640 x 480) pixels had a more useful 30 frames per second rate, but all video modes were also hindered somewhat by offering only automatic exposure, and monaural audio from a built-in microphone. Resolusi lebih rendah pilihan 720p (1.280 x 720 piksel) dan VGA (640 x 480) pixel memiliki 30 lebih berguna frame per tingkat kedua, tetapi semua modus video juga agak terhalang dengan menawarkan hanya eksposur otomatis, dan audio monaural dari built -di mikrofon. The Canon T2i corrects every one of these issues, with a new stereo microphone input jack, manual control of video exposure available, and a wide range of standard video frame rates on offer. The Canon T2i memperbaiki setiap masalah tersebut, dengan masukan baru jack mikrofon stereo, kontrol manual paparan video yang tersedia, dan berbagai macam frame rate video standar yang ditawarkan. At 1080p resolution, the user can select between 24, 25, and 30 frames per second. Pada resolusi 1080p, pengguna dapat memilih antara 24, 25, dan 30 frame per detik. For 720p and VGA shooting, both 50 and 60 fields per second modes are available. Untuk pengambilan gambar 720p dan VGA, baik 50 dan 60 bidang per Modus kedua yang tersedia. Users can also edit movies in camera, including the ability to chop off beginning or ends of movies, but only in one-second increments. Pengguna juga dapat mengedit film dalam kamera, termasuk kemampuan untuk memenggal awal atau ujung film, tapi hanya dengan penambahan satu detik.

Two features of the Canon T2i's video mode aren't available in the 7D, or for that matter any other Canon digital SLR to date. Dua fitur utama mode video T2i Canon tidak tersedia di 7D, atau dalam hal apapun SLR digital Canon lainnya hingga saat ini. The first, dubbed "Movie Crop" mode, is available only when shooting at standard-definition VGA resolution. Pertama, dijuluki "Movie Tanaman" mode, hanya tersedia pada saat pengambilan gambar pada resolusi VGA definisi standar. It works by simply cropping and recording the center-most 640 x 480 pixels from the sensor. Ia bekerja hanya dengan tanam dan rekaman pusat-paling 640 x 480 piksel dari sensor. This yields an effective 7x fixed zoom without interpolating the video. Ini menghasilkan sebuah 7x efektif tetap zoom tanpa interpolasi video. Of course, simply cropping the center of the image means that everything (including image noise) will be recorded at 1:1, so video has noticeably higher quality with the crop disabled. Tentu saja, cukup tanam di tengah gambar berarti bahwa segala sesuatu (termasuk gambar kebisingan) akan disimpan di 1:1, jadi video memiliki kualitas terasa lebih tinggi dengan tanaman dinonaktifkan. Still, for consumers who may well not be able to afford expensive telephoto lenses and only need standard-def output, it's an interesting feature. Namun, bagi konsumen yang mungkin tidak mampu membeli lensa tele mahal dan hanya perlu def standar output, ini merupakan fitur yang menarik.

The second movie feature specific to the T2i -- and rare among its DSLR brethren from any manufacturer -- is the ability to use autofocus during moving recording. Fitur Film kedua khusus untuk T2i - dan langka di antara saudara-saudara DSLR dari produsen apapun - adalah kemampuan untuk menggunakan autofocus selama perekaman bergerak. Continuous autofocus isn't available, so you have to manually trigger single AF operations as needed with a half-press of the shutter button. autofocus terus-menerus tidak tersedia, jadi anda harus secara manual memicu operasi tunggal AF diperlukan dengan menekan setengah tombol rana. The feature is something of a tradeoff, because the AF operation is clearly visible in the video, even if Canon's contrast detection AF implementation doesn't hunt around the point of focus as much as some we've seen. Fitur ini adalah sesuatu yang tradeoff, karena operasi AF jelas terlihat dalam video, bahkan jika deteksi kontras AF Canon pelaksanaan tidak berburu di sekitar titik fokus sebanyak beberapa kita lihat. AF noise is also very clearly captured on the movie's audio track, at least when using the internal microphone and 18-55mm kit lens -- using quieter USM lenses can mitigate this somewhat, and AF noise can be avoided altogether by using a good directional mic on a shock mount. kebisingan AF juga sangat jelas ditangkap pada audio track film tersebut, setidaknya ketika menggunakan mikrofon internal dan lensa kit 18-55mm - menggunakan lensa lebih tenang USM dapat mengurangi sedikit ini, dan AF kebisingan dapat dihindari sama sekali dengan menggunakan baik directional mic pada shock mount. Pros will certainly want to stick with focusing manually (and can choose to disable AF during movie capture to prevent accidental operation), but in the consumer market at which Canon's Rebel cameras are aimed, it makes sense to give customers the choice as to whether they feel the convenience of AF is worth putting up with the drawbacks. Kelebihan tentu akan ingin tetap dengan fokus manual (dan dapat memilih untuk AF menonaktifkan sepanjang film menangkap untuk mencegah operasi disengaja), tetapi di pasar konsumen di mana kamera Rebel Canon tersebut bertujuan, masuk akal untuk memberikan pelanggan pilihan untuk apakah mereka merasakan kenyamanan AF bernilai memasang dengan kekurangan.

HDMI output . HDMI output. The Canon T2i also upgrades the HDMI high-definition video output connectivity of the T1i, adding Consumer Electronics Control (HDMI-CEC) compatibility. The T2i Canon juga upgrade HDMI video high-definition konektivitas output dari T1i, menambahkan Consumer Electronics Control (HDMI-CEC) kompatibilitas. In layman's terms, this allows you to use your compatible high-def display's remote control to operate certain camera functions via the same cable through which the video signal is passed. Dalam istilah awam, ini memungkinkan Anda untuk menggunakan remote control yang kompatibel def tinggi layar untuk mengoperasikan fungsi kamera tertentu melalui kabel yang sama melalui sinyal video yang dilewatkan. Functions that can be controlled from the TV remote include single image playback, index display, shooting info display, image rotation, slide show, and movie playback. Fungsi yang dapat dikendalikan dari remote TV termasuk pemutaran gambar tunggal, menampilkan indeks, menembak Tampilan info, rotasi gambar, slide show, dan pemutaran film.

Lens . Lensa. The Canon T2i comes with the same kit lens that shipped with the XSi and T1i: the image-stabilized 18-55mm EF-S lens that so impressed us at its debut. The Canon T2i datang dengan lensa kit yang sama yang dikirimkan dengan XSi dan T1i: gambar-stabil lensa 18-55mm EF-S yang sangat terkesan kami di debut. Equivalent to a 29-88mm lens on a full-frame 35mm camera, this is a good mid-range zoom lens that is quite light. Setara dengan lensa 29-88mm pada full frame-35mm kamera, ini adalah pertengahan yang baik-range zoom lensa yang cukup ringan. Optical image stabilization technology delivers sharper shots even in low light. Optical teknologi stabilisasi gambar memberikan tembakan tajam bahkan dalam cahaya rendah. Canon claims you can shoot at up to four stops slower than normal and still get a stable shot. Canon klaim Anda dapat menembak hingga empat berhenti lebih lambat dari normal dan masih mendapatkan suntikan stabil. That means that if you can normally get a stable shot at 1/60 second, you should be able to squeeze off a 1/4 second shot and have it come out sharp. Itu berarti bahwa jika Anda biasanya dapat mendapatkan ditembak stabil di 1 / 60 detik, Anda harus mampu memeras off menembak 1 / 4 kedua dan memilikinya keluar tajam. If you're a fairly steady shooter, it seems to be true. Jika Anda adalah seorang penembak cukup stabil, tampaknya benar. Your results may vary, and remember that image stabilization compensates for camera movement, not for subject movement, so when shooting in low light tell your subject to hold very still, or shoot with a faster shutter speed at a higher ISO. Hasil Anda mungkin berbeda, dan ingat bahwa stabilisasi gambar mengkompensasi gerakan kamera, bukan untuk gerakan subjek, sehingga pada saat pengambilan gambar di cahaya rendah kirim subjek Anda untuk terus diam, atau menembak dengan kecepatan rana yang lebih cepat pada ISO yang lebih tinggi.

Storage and battery . Penyimpanan dan baterai. The Canon Rebel T2i uses SD, SDHC, and SDXC memory cards. Pemberontak itu T2i Canon menggunakan SD, SDHC, dan kartu memori SDXC. This latter standard should allow card sizes up to 2 terabytes, while SDHC is limited to 32GB. Standar ini terakhir harus memungkinkan kartu ukuran hingga 2 terabyte, sedangkan SDHC dibatasi hingga 32GB.

Direct support for Eye-Fi wireless cards has found its way into the Canon T2i, complete with a dedicated status display that only appears if the card is installed. dukungan langsung untuk kartu Eye-Fi nirkabel telah menemukan jalan ke T2i Canon, lengkap dengan menampilkan status khusus yang hanya muncul jika kartu terpasang. The new display shows when a card is connecting, has connected, is transmitting, and when a card has a problem connecting. Layar baru menunjukkan saat kartu adalah menghubungkan, telah terhubung, adalah transmisi, dan ketika kartu memiliki masalah menghubungkan.

The Canon T2i uses a new battery, the LP-E8 -- a 7.2V, 1120 mAh lithium-ion battery with concealed electrical contacts. The Canon T2i menggunakan baterai baru, LP-E8 - sebuah 7.2V, 1120 mAh lithium-ion baterai dengan kontak listrik tersembunyi. Expected battery life is 440 shots at 72F, and 400 shots at 32F, based on CIPA testing standards which dictate 50% flash usage. hidup baterai yang diharapkan 440 tembakan di 72F, dan 400 tembakan di 32F, berdasarkan standar CIPA pengujian yang mendikte 50% penggunaan flash. That's about a ten percent improvement over the T1i's battery life, but still below average for an SLR. Itu tentang peningkatan sepuluh persen atas hidup baterai T1i, tetapi masih di bawah rata-rata untuk sebuah SLR. The Canon T2i's new battery also means that the camera requires a new grip, the BG-E8. baterai baru yang T2i Canon juga berarti bahwa kamera memerlukan pegangan baru, BG-E8. It duplicates the shutter release and control wheel, as well as AE lock and focus point buttons for vertical-format shooting. Ini duplikat pelepas rana dan roda kontrol, serta kunci dan fokus AE tombol titik untuk-format pengambilan gambar vertikal. Those who have trouble with the smaller grip on the Canon Rebel series will find that the battery grip makes the camera more satisfying to use; and those who frequently shoot in portrait orientation will enjoy the vertical shutter release, which allows you to shoot with less strain. Mereka yang mengalami masalah dengan pegangan yang lebih kecil pada seri Canon Rebel akan menemukan bahwa baterai grip membuat kamera lebih memuaskan untuk menggunakan, dan mereka yang sering menembak dalam orientasi potret akan menikmati shutter release vertikal, yang memungkinkan Anda untuk menembak dengan mengurangi ketegangan . A new optional infrared remote, the RC-6 is also available for the Canon Rebel T2i, said to combine the features of the older RC-1 and RC-5 wireless remotes. Sebuah pilihan baru inframerah terpencil, RC-6 juga tersedia untuk Canon Rebel T2i itu, katanya menggabungkan fitur dari RC lebih tua-1 dan 5 RC-remote nirkabel.

Shooting with the Canon Rebel T2i Menembak dengan Canon Rebel T2i

Loads of resolution . Banyak resolusi. Not surprisingly given its heritage, the T2i's sensor gathers loads of detail, and begs for a really good lens. Tidak mengherankan diberikan warisan, sensor T2i yang mengumpulkan banyak detail, dan memohon untuk lensa benar-benar baik. The 18-55mm kit lens is impressive for its cost, but in this detail-rich garden shot, its limits appear to have been reached. Lensa kit 18-55mm sangat mengesankan untuk biaya, tetapi dalam taman ini ditembak kaya detail, batas-batasnya tampaknya telah tercapai.

Thanks to a control layout that's very similar to that of the T1i, I found myself immediately at home shooting with the Canon Rebel T2i and its EF-S 18-55mm f/3.5-5.6 IS kit lens. Berkat tata letak kontrol yang sangat mirip dengan yang dari T1i, aku menemukan diriku dengan segera di rumah menembak dengan Canon Rebel T2i dan yang EF-S 18-55mm f/3.5-5.6 IS lensa kit. Among the Canon T2i's external changes, I particularly appreciated the new 3:2 aspect ratio LCD. Di antara perubahan eksternal T2i Canon, aku terutama menghargai rasio aspek 03:02 LCD baru. Viewing full images, there are no longer any black borders at the edges of the screen. Melihat gambar penuh, tidak ada lagi batas hitam di tepi layar. This means a slightly larger review than was previously the case, even though the actual screen area has fallen just slightly. Ini berarti review sedikit lebih besar dari sebelumnya kasus ini, meskipun area layar yang sebenarnya telah jatuh hanya sedikit. I understand that the viewing angle has also been reduced slightly, but this wasn't really noticeable -- the Canon T2i's display is still easily visible from a wide range of angles, perfect for everybody to huddle around and review group portraits. Saya memahami bahwa sudut pandang juga telah berkurang sedikit, tetapi ini tidak benar-benar terlihat - menampilkan T2i Canon masih dengan mudah terlihat dari berbagai sudut, cocok untuk semua orang meringkuk di sekitar dan meninjau potret kelompok.

The Canon T2i only has one new button, but the profiles of several other buttons have also been changed as part of accommodating the wider LCD display. The T2i Canon hanya memiliki satu tombol baru, namun profil beberapa tombol lainnya juga telah diubah sebagai bagian dari menampung layar LCD yang lebih luas. I found the variation in button size and shape helpful, making it significantly easier to identify buttons by touch alone, and saving me removing my eye from the viewfinder so frequently. Saya menemukan variasi dalam ukuran dan bentuk tombol membantu, sehingga lebih mudah untuk mengidentifikasi tombol dengan sentuhan sendiri, dan menyelamatkan saya menghapus mata saya dari jendela bidik begitu sering. The new dedicated Live View / Movie Record button is perfectly situated, easily within reach when needed, but far enough from the thumb rest that I never accidentally bumped it. Yang didedikasikan baru Live View / Movie tombol Rekam terletak sempurna, mudah dijangkau bila diperlukan, tapi cukup jauh dari ibu jari yang lain saya pernah sengaja bertabrakan itu. The place of the previous shared LV / Movie button has been taken by a Quick Menu function adopted from the previous EOS 7D design, and this proved extremely convenient for making quick settings changes without needing to dip into the T2i's menu system. Tempat tombol bersama sebelumnya / LV Movie telah diambil oleh fungsi Quick Menu diadopsi dari desain EOS 7D sebelumnya, dan ini terbukti sangat mudah digunakan untuk membuat perubahan pengaturan cepat tanpa perlu mencelupkan ke dalam sistem menu T2i's.

The only control element on the T2i that I felt could use some improvement was the Main dial, situated right behind the Shutter button. Elemen kontrol hanya di T2i bahwa saya merasa dapat menggunakan beberapa perbaikan adalah tombol Utama, terletak tepat di belakang tombol rana. I found its resistance significantly too high, and as a result, had to press my fingertip against its knurled surface to make settings changes. Saya menemukan resistensi secara signifikan terlalu tinggi, dan sebagai hasilnya, harus tekan ujung jari saya terhadap permukaan Knurled untuk melakukan perubahan pengaturan. When making a lot of adjustments with the dial -- shooting in Priority or Manual modes, for example -- my hand quickly tired, and my fingertip started to feel a little sore. Ketika membuat banyak penyesuaian dengan memutar - penembakan di Prioritas atau mode Manual, misalnya - tanganku cepat lelah, dan ujung jari saya mulai merasa sedikit sakit.

Blown highlights . Highlight. I frequently needed to dial in anywhere from 1/3 to 2/3EV of negative exposure compensation when using evaluative metering. Aku sering dibutuhkan untuk dial di mana saja dari 1 / 3 sampai 2/3EV kompensasi eksposur negatif ketika menggunakan metering evaluatif. The default exposure for this shot rendered the white bricks with blown highlights, and the red channel was badly clipped on the truck's yellow and red paint. Eksposur standar untuk ini diberikan tembakan batu bata putih dengan highlight, dan saluran merah parah dijepitkan pada cat truk kuning dan merah. This shot required -2/3EV of exposure compensation. Gambar ini diperlukan -2/3EV kompensasi eksposur.

In terms of image quality, the Canon T2i performed as well as I'd expected -- not surprisingly given the close relationship between its image sensor, and that of the prosumer EOS 7D. Dari segi kualitas gambar, Canon T2i dilakukan serta aku diharapkan - tidak mengherankan mengingat hubungan erat antara sensor gambar, dan bahwa dari prosumer EOS 7D. It was perhaps straining the optical limits of its 18-55mm kit lens, and I'd have loved the opportunity to shoot using some of Canon's higher-end glass, but unless viewed at 1:1 resolution I found its images to offer plenty of detail, and with relatively low noise. Itu mungkin tegang batas optik lensa kit 18-55mm, dan aku akan menyukai peluang untuk menembak dengan menggunakan beberapa kaca Canon lebih tinggi-end, tetapi jika dilihat di 1:01 resolusi saya menemukan gambar untuk menawarkan banyak detail, dan dengan kebisingan yang relatif rendah. I did note a tendency to overexpose a little to my own tastes, though, with many shots needing somewhere between 1/3 and 2/3 EV of negative exposure compensation. Aku catatan kecenderungan untuk overexpose sedikit dengan selera saya sendiri, meskipun, dengan banyak gambar yang memerlukan suatu tempat antara 1 / 3 dan 2 / 3 EV dari kompensasi eksposur negatif.

I found Canon's menu design on the T2i was among the clearest and easiest to understand compared to current digital SLRs, but I did find a few elements somewhat confusing. Saya menemukan menu desain Canon pada T2i merupakan salah satu yang paling jelas dan paling mudah untuk memahami dibandingkan dengan SLR digital saat ini, tapi aku menemukan beberapa elemen agak membingungkan. Several functions related to Live View are adjusted from a dedicated Live View function settings page, but it's not accessed from the Record menus, where I'd expect to find it. Beberapa fungsi yang berhubungan dengan Live View disesuaikan dari halaman Lihat didedikasikan fungsi pengaturan Live, tapi tidak diakses dari menu Record, tempat aku berharap untuk menemukannya. Instead, it's rather confusingly located in Setup Menu 2. Sebaliknya, ini agak membingungkan terletak di Menu Setup 2. Several of its options are also shared with the Canon T2i's Movie mode, whose controls appear in two menus that only appear when the camera's Mode dial is set to Movie mode. Beberapa pilihan tersebut juga berbagi dengan mode Movie yang T2i Canon, kontrol yang muncul dalam dua menu itu hanya muncul bila kamera Mode dial diatur ke mode Movie. If these settings are adjusted in the Live View function settings page, they also change in the Movie menus (and vice versa), which could cause photographers a little confusion. Jika pengaturan ini disesuaikan pada halaman pengaturan fungsi Lihat Live, mereka juga perubahan menu Movie (dan sebaliknya), yang bisa menyebabkan kebingungan sedikit fotografer. I also thought the placement of the Histogram option in Playback Menu 2 was a little curious, given that it also affects the Live View mode's Histogram function. Aku juga berpikir penempatan opsi Histogram di Putar Menu 2 adalah sedikit aneh, mengingat bahwa hal itu juga mempengaruhi modus Lihat Live fungsi Histogram. I believe the option might be better situated in the Setup menus. Saya percaya pilihan mungkin lebih baik terletak di menu Setup. These quirks aside, though, I found the Canon T2i's menus easy to navigate, and the My Menu group was particularly useful for quickly recalling frequently changed settings. Quirks samping ini, aku menemukan menu yang T2i Canon mudah dinavigasi, dan kelompok Menu saya sangat berguna untuk cepat mengingat pengaturan sering berubah.

Perhaps the big story of the Canon T2i is its Movie mode, which brings the feature set of Canon's prosumer EOS 7D model down to a much more affordable price point -- and even adds a couple of functions that aren't available in the 7D. Mungkin cerita besar dari T2i Canon adalah perusahaan Movie mode, yang membawa fitur set prosumer Canon EOS 7D model turun ke titik harga jauh lebih terjangkau - dan bahkan menambahkan beberapa fungsi yang tidak tersedia di 7D. I must confess that I'm not much of a movie shooter myself, but nonetheless was rather impressed with the range of control on offer. Saya harus mengakui bahwa saya tidak banyak penembak film sendiri, tapi tetap agak terkesan dengan rentang kontrol yang ditawarkan. The ability to shoot video with completely manual exposure is still rather rare among DSLRs at any price point, and will likely prove very appealing to advanced amateur and pro videographers on a budget, affording them with complete control over the look of their movies. Kemampuan untuk mengambil gambar video dengan eksposur sepenuhnya manual masih agak jarang di antara DSLRs pada setiap titik harga, dan mungkin akan terbukti sangat menarik bagi videographers amatir dan pro maju pada anggaran, affording mereka dengan kontrol penuh atas penampilan film mereka. Likewise, the option to use an external microphone is desirable for advanced amateurs, although the T2i doesn't offer control over recording levels, and so pros will likely still need to rely on an external device for audio capture in more challenging environments. Demikian pula, pilihan untuk menggunakan mikrofon eksternal diinginkan untuk amatir lanjutan, meskipun T2i tidak menawarkan kontrol atas tingkat perekaman, dan pro akan cenderung masih perlu mengandalkan perangkat eksternal untuk menangkap audio dalam lingkungan yang lebih menantang. The ability to crop pixels from the center of the image sensor in standard-definition movie shooting helps consumers who can't afford expensive telephoto lenses to get closer to their subject. Kemampuan untuk tanaman piksel dari pusat sensor gambar dalam shooting film standard-definition membantu konsumen yang tidak mampu lensa tele yang mahal untuk mendekati subjek mereka.

AF during movie capture . AF selama pengambilan film. If a big adjustment is needed, the kit lens is rather noisy, but for small adjustments like in this video, the ability to perform single AF operations is probably quick and quiet enough for many consumers. Jika diperlukan penyesuaian besar, lensa kit agak berisik, tapi untuk penyesuaian kecil seperti dalam video ini, kemampuan untuk melakukan operasi tunggal AF mungkin cepat dan cukup tenang bagi banyak konsumen. (Shot in standard definition VGA mode.) File Size: 52.7MB (Shot pada mode VGA standar definisi) File. Ukuran: 52.7MB

The ability to perform single autofocus operations during movie capture is becoming more common, but I found my enthusiasm for the ability rather tempered by just how obtrusive AF noise was when using the Canon T2i's 18-55mm kit lens, at least if anything more than minor adjustments were needed. Kemampuan untuk melakukan operasi tunggal autofocus selama pengambilan film menjadi lebih umum, tapi saya menemukan antusiasme saya untuk kemampuan lebih marah dengan betapa menonjol kebisingan AF saat menggunakan lensa kit 18-55mm yang T2i Canon, setidaknya jika ada lebih dari kecil penyesuaian yang diperlukan. I wasn't able to try the feature with a current Canon USM lens, but did try using an aged film-era Canon USM lens which I had on hand, and while it was still clearly audible, I felt it at least produced a less high-pitched and objectionable noise. Saya tidak dapat mencoba fitur tersebut dengan lensa Canon USM saat ini, tapi coba gunakan film-era berusia lensa Canon USM yang saya telah di tangan, dan sementara itu masih jelas terdengar, saya merasa paling tidak menghasilkan kurang melengking dan pantas kebisingan. Perhaps current USM lenses would fare even better, and even the kit lens is fairly quiet if only a very small AF adjustment is needed. Mungkin lensa USM tarif saat ini akan lebih baik, dan bahkan lensa kit cukup tenang jika hanya penyesuaian AF sangat kecil diperlukan. I still applaud Canon for offering the capability to focus, if for no other reason than that it allows amateur photographers to choose whether they're willing to put up with the drawbacks, rather than having the decision made for them. Aku masih memuji Canon untuk menawarkan kemampuan untuk fokus, jika tidak ada alasan lain selain bahwa hal itu memungkinkan fotografer amatir untuk memilih apakah mereka bersedia dengan kekurangan, daripada keputusan yang dibuat untuk mereka. With modern video editing software it's relatively simple to crop out the AF operations after the fact, or simply overlay a different soundtrack on the video. Dengan perangkat lunak editing video modern ini relatif sederhana untuk tanaman keluar setelah operasi AF fakta, atau hanya overlay soundtrack berbeda pada video.

Equally useful for consumer videographers is the Canon T2i's movie crop function, available only when shooting in standard definition mode. Sama-sama berguna untuk videographers konsumen film fungsi tanaman T2i Canon, tersedia hanya pada saat pengambilan gambar dalam modus definisi standar. Of course since this uses 1:1 resolution data from the image sensor, it will more prominently show off image noise and lens defects, but the result is still likely to prove more satisfactory than the powerful digital zooms to be found on most dedicated camcorders. Tentu saja karena ini menggunakan data 1:01 resolusi dari sensor gambar, itu akan lebih mencolok pamer noise gambar dan cacat lensa, tetapi hasilnya masih cenderung untuk membuktikan lebih memuaskan daripada membesarkan digital kuat dapat ditemukan pada camcorder paling berdedikasi. Given that powerful telephoto lenses are priced out of the reach of most amateurs, I think the crop mode is a genuinely useful feature for the Rebel T2i's target market. Mengingat bahwa lensa tele kuat adalah harga di luar jangkauan kebanyakan amatir, saya pikir modus tanaman adalah fitur yang benar-benar berguna bagi target pasar Rebel T2i's.

One minor issue I encountered in my movie shooting with the Canon T2i related to its microphone placement, and my own grip on the camera. Satu masalah kecil yang saya temui dalam film saya menembak dengan Canon T2i terkait dengan penempatan mikrofon, dan pegangan sendiri pada kamera. I generally shoot two-handed for stability, but tend to change my grip slightly when shooting video with a DSLR. Saya biasanya menembak dua tangan untuk stabilitas, tapi cenderung mengubah pegangan saya sedikit saat pengambilan gambar video dengan DSLR. Ordinarily, my left hand grips the lens barrel, but given that I lack the smoothness to adjust focus or zoom to my satisfaction during video shooting, I've grown accustomed to moving my left hand away from the lens during video capture. Biasanya, genggaman tangan kiriku laras lensa, tetapi mengingat bahwa aku kurang halus untuk mengatur fokus atau zoom untuk kepuasan saya selama pengambilan gambar video, saya sudah terbiasa untuk menggerakkan tangan kiri saya jauh dari lensa selama capture video. Instead, I hold the left end of the camera body. Sebaliknya, saya memegang ujung kiri bodi kamera. My issue was that in doing so, I occasionally brushed my middle finger across the microphone, or even accidentally covered it altogether, disrupting my movie audio. masalah saya adalah bahwa dengan melakukan hal itu, saya kadang-kadang menggosok jari tengah saya di mikrofon, atau bahkan sengaja ditutupi sama sekali, mengganggu audio film saya. Once I was aware of this, it was easy enough to consciously make myself grip the body in a more traditional style, but a different microphone placement could resolve the issue altogether. Setelah saya menyadari ini, cukup mudah untuk secara sadar membuat diriku pegangan tubuh dengan gaya yang lebih tradisional, namun penempatan mikrofon yang berbeda dapat mengatasi masalah sama sekali. (It seems to me that beneath the pentamirror prism would be an ideal location which wouldn't likely be bumped or covered). (Sepertinya saya bahwa di bawah prisma pentamirror akan menjadi lokasi yang ideal yang tidak kemungkinan besar akan bertemu atau ditutupi).

VGA video crop . VGA video tanaman. The Canon T2i's video crop mode gets you much closer to the action, at the expense of image sharpness and noise. modus video tanaman The Canon T2i membuat Anda lebih dekat dengan tindakan, dengan mengorbankan ketajaman gambar dan suara. Panning at this speed took all my concentration, so before filming, I prefocused on the bridge support at the six second point in the video, using the camera's contrast detect AF. Panning pada kecepatan ini mengambil semua konsentrasi saya, jadi sebelum syuting, saya prefocused pada dukungan jembatan di titik enam kedua di video, menggunakan kontras kamera mendeteksi AF. The resulting video is a bit soft, but probably acceptable to many consumers -- certainly when compared to the expense of a similarly powerful telephoto lens. Video yang dihasilkan agak sedikit lunak, tetapi mungkin dapat diterima banyak konsumen - tentu saja jika dibandingkan dengan biaya lensa tele sama kuat. File Size: 29.6MB Ukuran File: 29.6MB

Another feature of the Canon T2i that I welcomed was its modest increase in burst shooting rate. Fitur lain dari T2i Canon bahwa aku menyambut meningkat yang sederhana di tingkat menembak meledak. The difference between the T1i's 3.4 frames per second, and the 3.7 fps of the T2i is certainly not night and day, but I thought it both noticeable and worthwhile. Perbedaan antara 3,4 yang T1i's frame per detik, dan 3,7 fps dari T2i jelas bukan siang dan malam, tapi saya pikir itu terlihat baik dan berharga. My reflexes are perhaps not the best, and so when shooting unpredictable subjects such as children and pets, I frequently take advantage of a camera's burst capabilities, quickly firing several shots when I think the moment right. refleks saya adalah mungkin bukan yang terbaik, sehingga pada saat pengambilan gambar subjek yang tak terduga seperti anak-anak dan hewan peliharaan, saya sering mengambil keuntungan dari kemampuan burst kamera, segera menembak beberapa gambar ketika saya berpikir kanan saat ini. Every little bit helps with this approach, and the only real downside of the increased burst speed is that it is accompanied by a significant reduction in burst depth. Setiap sedikit membantu dengan pendekatan ini, dan satunya downside nyata dari peningkatan kecepatan meledak adalah bahwa hal itu disertai oleh penurunan yang signifikan secara mendalam meledak. All but the most extreme JPEG shooters will likely still be fine, with roughly 34 large/fine shots possible before the camera slows down. Semua kecuali yang paling ekstrem JPEG penembak kemungkinan masih akan baik-baik saja, dengan sekitar 34 besar / foto baik kamera mungkin sebelum melambat.

Raw shooters such as myself are likely to find the six-shot buffer rather limiting, however. Shooters baku seperti diriku cenderung menemukan enam-shot buffer agak membatasi, namun. I occasionally found myself wishing for the T1i's somewhat more useful nine-shot capability as I waited for their buffer to empty. Aku kadang-kadang menemukan diri saya berharap untuk T1i agak lebih berguna kemampuan menembak sembilan-saat aku menunggu untuk buffer mereka untuk mengosongkan. (I should note that the burst depth in both Raw and JPEG modes does vary with subject detail, and so in some scenes you may find more or less shots are available. I also noticed that disabling the Auto Lighting Optimizer and Peripheral Illumination Correction functions gave a modest increase in JPEG burst depth.) (Saya harus mencatat bahwa kedalaman meledak di kedua mode JPEG baku dan tidak bervariasi dengan detail subjek, dan sehingga dalam beberapa adegan Anda mungkin menemukan gambar lebih atau kurang yang tersedia. Saya juga melihat bahwa mematikan Auto Lighting Optimizer dan Penerangan Peripheral Koreksi fungsi memberikan sedikit peningkatan di kedalaman meledak JPEG.)

All things considered, the Canon T2i is a very enjoyable camera to use, with impressive image quality and a generous range of features for a consumer DSLR. Semua hal dipertimbangkan, T2i Canon adalah kamera yang sangat menyenangkan untuk digunakan, dengan kualitas gambar yang mengesankan dan murah berbagai fitur untuk DSLR konsumen. As noted, I'm largely a stills shooter who just occasionally dips into video to document family outings, but were I more of a videographer, the Canon T2i's depth of control over video shooting would likely have me beside myself with excitement. Sebagaimana tercatat, sebagian besar aku penembak stills dips yang hanya sesekali ke dalam video untuk mendokumentasikan acara keluarga, namun aku lebih videografer sebuah, kedalaman T2i Canon kontrol atas Video shooting mungkin akan saya di samping diri dengan kegembiraan.

Canon T2i versus Canon T1i at ISO 1,600 Canon Canon versus T2i T1i pada ISO 1600

Canon T2i at ISO 1,600 Canon T2i pada ISO 1600	Canon T1i at ISO 1,600 Canon T1i pada ISO 1600
The Canon T2i's 18-megapixel sensor is an improvement on the 15-megapixel T1i, with sharper detail and less noise overall at ISO 1,600. Sensor T2i Canon 18-megapixel adalah perbaikan pada T1i 15-megapiksel, dengan detail lebih tajam dan lebih sedikit noise pada ISO 1600 secara keseluruhan. Pretty impressive. Cukup mengesankan. The red leaf fabric still gives the T2i trouble, though. Kain merah daun masih memberikan masalah T2i, though.

Canon T2i versus Nikon D5000 at ISO 1,600 Canon versus Nikon T2i D5000 pada ISO 1600

Canon T2i at ISO 1,600 Canon T2i pada ISO 1600	Nikon D5000 at ISO 1,600 Nikon D5000 pada ISO 1600
Up against the Nikon D5000, the Canon T2i out-resolves its 12-megapixel competitor in most situations, and there's less shadow chroma noise. Up terhadap D5000 Nikon, Canon T2i keluar-resolve pesaingnya 12-megapiksel dalam kebanyakan situasi, dan ada sedikit bayangan kroma kebisingan. The Nikon still does better with the red leaf swatch, though, thanks to its better-controlled anti-noise suppression. Nikon masih tidak lebih baik dengan carikan daun merah, meskipun, berkat lebih baik dikontrol penekanan anti-kebisingan.

Canon T2i versus Pentax K7 at ISO 1,600 Canon versus T2i Pentax K7 pada ISO 1600

Canon T2i at ISO 1,600 Canon T2i pada ISO 1600	Pentax K7 at ISO 1,600 Pentax K7 pada ISO 1600
The Pentax K7 isn't known for its superior high-ISO performance, but it's closer in resolution than most, and still does a fair job against the T2i. The K7 Pentax tidak dikenal karena kinerja superior ISO tinggi, tapi lebih dekat dalam resolusi daripada kebanyakan, dan masih melakukan pekerjaan yang adil terhadap T2i. The Canon T2i's sensor out-resolves the K7, though, while maintaining better detail overall. The Canon T2i sensor luar menerjemahkan K7, meskipun, tetap menjaga detail yang lebih baik secara keseluruhan.

Canon T2i versus Nikon D700 at ISO 1,600 T2i Canon versus Nikon D700 di ISO 1600

Canon T2i at ISO 1,600 Canon T2i pada ISO 1600	Nikon D700 at ISO 1,600 Nikon D700 di ISO 1600
The T2i does so well, it's only fair to put it up against the full-frame Nikon D700. The T2i tidak begitu baik, itu hanya adil untuk mendirikannya terhadap frame-penuh Nikon D700. While the resolution doesn't make it a match, it's easy to see the advantage of larger pixels over more pixels, especially when looking a the red swatch. Sementara resolusi itu tidak membuatnya cocok, mudah untuk melihat keuntungan dari piksel yang lebih besar lebih banyak piksel, terutama ketika melihat secarik merah. The D700 gets less detail in the Mosaic area, sure, but when it comes to red leaf swatch, the D700 has more to true detail to work with, rendering the fabric more accurately than any other camera in this lineup. D700 ini mendapatkan detail kurang di daerah Musa, pasti, tapi ketika datang ke carikan daun merah, D700 memiliki lebih untuk detail benar untuk bekerja dengan, rendering kain lebih akurat dibanding kamera lain di barisan ini. But remember, the Nikon D700 is still priced at $2,700, three times the price of the Canon T2i. Tapi ingat, Nikon D700 masih harga $ 2.700, tiga kali harga T2i Canon.

Detail comparison . Detail perbandingan. An ISO 1,600 comparison is only so helpful. ISO 1600 perbandingan ini hanya sangat membantu. A camera's ISO 100 performance is also of value, as is a higher ISO, so I've pitted the same set of cameras against each other in the high-contrast detail department at 200 and 3,200. The Canon T2i produces the most crisp image from this area of the Still Life shot, but it is also employing a lot of sharpening, which leaves halos around the letters in this picture. Contrast is also more prominent in the T2i. The others do well, but the Canon T2i truly wins the day. Also consider that this test is not independent of lens quality, focus errors, and other variables, so again take this mostly as a comparison of what each camera was able to do with the best standardized optics we can muster. Juga mempertimbangkan bahwa tes ini tidak terlepas dari kualitas lensa, kesalahan fokus, dan variabel lainnya, sehingga sekali lagi mengambil ini kebanyakan sebagai perbandingan dari apa yang setiap kamera mampu melakukan dengan optik standar terbaik yang dapat kita kerahkan. Each of these cameras used one of our standard Sigma 70mm f/2.8 EX DG Macro lenses.

Main dial has too much resistance, is uncomfortable in use No rear control dial Evaluative metering tends to blow highlights, often requires 1/3 to 2/3EV of negative exposure compensation No dedicated AF-assist lamp (flash is used), and AF-assist adjustment is buried in the menu system No wireless flash control Live View and Histogram menu items placed in illogical menu pages No intervalometer or multiple exposure support No in-camera image stabilization (lens based) No in-camera lateral chromatic aberration correction Kit lens slightly soft; 18-megapixel sensor demands very good lenses for best results Kit lens produces somewhat high barrel distortion and chromatic aberration at wide-angle Front lens barrel rotates on kit lens, making polarizer lens use difficult Flash coverage is uneven, falling off in the corners at wide-angle Slightly below average accuracy from the optical viewfinder No continuous autofocus in Movie mode Single AF during movie recording is very clearly audible with kit lens Microphone placement dictates attention to proper grip during movie recording Auto white balance leaves tungsten lighting too warm High ISO noise suppression has trouble with low-contrast areas, especially in the red channel Buffer fills very quickly when shooting in RAW mode Peripheral Illumination Correction and Auto Lighting Optimizer reduce JPEG burst depth Battery capacity is slightly better than T1i, but still below average No AF Microadjustment feature Shutter is noisy

Once again, Canon has raised the bar at the consumer level, providing even more still-image resolution, and a high-def video mode with full control over exposure, resolution and frame rate, plus the ability to use autofocus during videos. Sekali lagi, Canon telah mengangkat bar di tingkat konsumen, memberikan resolusi lebih masih gambar, dan mode video high-def dengan kontrol penuh atas eksposur, resolusi dan frame rate, ditambah kemampuan untuk menggunakan autofocus sewaktu video. Though it comes at a noticeably lower price, the Canon T2i handily trumps the competition from Nikon and others, and offers some timely features worth noticing. Meskipun datang dengan harga terasa lebih rendah, Canon dgn mudah mengalahkan T2i persaingan dari Nikon dan orang lain, dan menawarkan beberapa fitur yang tepat waktu senilai memerhatikan.

The Eye-Fi status display stands out as a great idea that seems rather obvious in hindsight, but technical achievements like the iFCL metering, which helps autofocus accuracy by detecting the type of light, are where the Canon T2i really impresses. Tampilan status Eye-Fi berdiri sebagai suatu ide cemerlang yang agak jelas di belakang, tapi prestasi teknis seperti metering iFCL, yang membantu akurasi autofocus dengan mendeteksi jenis cahaya, yang mana Canon T2i benar-benar mengesankan.
