What Lenses Can You

How Align Camera Lens With Sensor

The previous section helped you sort out what lens you need to buy with your T2i (assuming you already didn't own any Canon lenses). Now, you're probably wondering what lenses can be added to your growing collection (trust me, it will grow). You need to know which lenses are suitable and, most importantly, which lenses are fully compatible with your Rebel T2i. With the Canon T2i, the compatibility issue is a simple one It accepts any lens with the EF or EF-S designation, with full availability...

Displaying Histograms

Canon Histogram

To view histograms on your screen, press the DISP button while an image is shown on the LCD. Keep pressing the button until the histogram s are shown. The display will cycle between several levels of information, including flashing highlights and two histograms. One histogram shows overall brightness levels Figure 4.24 , while the second type of histogram screen shows both brightness levels and levels for each of the red, green, and blue channels see Figure 4.25 . During histogram display,...

External Flash Function Setting

Canon Harici Fla Ayarlar

This menu is available only when you have a compatible dedicated Canon Speedlite electronic flash attached and switched on. The settings available with the 580 EX II and 430 EX are shown in Figure 7.12. If you press the DISP button while adjusting flash settings, both the changes made to the settings of an attached external flash and to the built-in flash will be cleared. Flash mode. This entry allows you to set the flash mode for the external flash, from E-TTL II, A-TTL, or TTL. All three...

Adjusting White Balance

I showed you how to adjust white balance in Chapter 3, using the T2i's built-in presets, white balance shift capabilities, and white balance bracketing there's more on bracketing in Chapter 4, too . In most cases, however, the Rebel T2i will do a good job of calculating white balance for you, so Auto can be used as your choice most of the time. Use the preset values or set a custom white balance that matches the current shooting conditions when you need to. The only really problematic light...

Setting Up Your Canon EOS Rebel TD

Canon has made the migration path through its Rebel (formerly Digital Rebel) digital camera line so seductively easy that it's a safe bet that many of you are jumping to this latest entry-level model directly from an earlier EOS camera, like the Rebel XSi, or even the relatively new T1i. The enhanced features of the Canon EOS Rebel T2i 550D are hard to resist, including a whopping 18 megapixels of resolution and honest HDTV movie-making capabilities. So, if you do have experience with a...

Canon Picture Styles

Canon 550d Sharpness

Picture Styles are extremely flexible. Canon has set the parameters for the five predefined color Picture Styles and the single monochrome Picture Style to suit the needs of most photographers. But you can adjust any of those canned Picture Styles to settings you prefer. Better yet, you can use those three User Definition files to create brand new styles that are all your own. If you want rich, bright colors to emulate Velvia film or the work of legendary photographer Pete Turner, you can build...

Adep And Hyperfocal Distance

Canon 550d Display Raw Jpeg Quality Mode

A-DEP is a simplified version of a related mode found in some higher-end Canon digital and film models called DEP. DEP allows you to manually select the nearest and farthest points you want in focus, and the camera will then adjust the focus point to a setting known as the hypefocal distance. At the hyperfocal distance, everything from half that distance to infinity will be in acceptable focus. Although many photographers elect to set hyperfocal distance themselves, the exact distance varies by...

Avoiding Sync Speed Problems

Using a shutter speed faster than 1 200th second can cause problems. Triggering the electronic flash only when the shutter is completely open makes a lot of sense if you think about what's going on. To obtain shutter speeds faster than 1 200th second, the T2i exposes only part of the sensor at one time, by starting the second curtain on its journey before the first curtain has completely opened, as shown in Figure 7.9. That effectively provides a briefer exposure as the open slit between the...

White Balance Library

Shoot a selection of blank-card images under a variety of lighting conditions on a spare memory card. If you want to recycle one of the color temperatures you've stored, insert the card and set the custom white balance to that of one of the images in your white balance library, as described above. White balance shift allows you to dial in a white balance color bias along the blue amber yellow dimensions, and or magenta green scale. In other words, you can set your color balance so that it is a...

Avoiding Potential Wide Angle Problems

Fisheye Lens Canon Rebel T2i

Wide-angle lenses have a few quirks that you'll want to keep in mind when shooting so you can avoid falling into some common traps. Here's a checklist of tips for avoiding common problems Symptom converging lines. Unless you want to use wildly diverging lines as a creative effect, it's a good idea to keep horizontal and vertical lines in landscapes, architecture, and other subjects carefully aligned with the sides, top, and bottom of the frame. That will help you avoid undesired perspective...

Digital Photo Professional

Digital Photo Professional, introduced earlier in this chapter, is preferred by many for Canon dSLR cameras like the Rebel T2i. DPP offers much higher speed processing of RAW images than was available with the late, not lamented, sluggardly File Viewer Utility (as much as six times faster). Canon says this utility rivals third-party standalone and plug-in RAW converters in speed and features. It supports both Canon's original CRW format and the newer CR2 RAW format used by the T2i, along with...

Working with Long Exposures

Long Exposures With Filter

Because the Rebel T2i produces such good images at longer exposures, and there are so many creative things you can do with long exposure techniques, you'll want to do some experimenting. Get yourself a tripod or another firm support and take some test shots with long exposure noise reduction both enabled and disabled to see whether you prefer low noise or high detail and get started. Here are some things to try Make people invisible. One very cool thing about long exposures is that objects that...

Three Ways to Take Long Exposures

There are actually three common types of lengthy exposures timed exposures, bulb exposures, and time exposures. The Rebel T2i offers only the first two, but once you understand all three, you'll see why Canon made the choices it did. Because of the length of the exposure, all of the following techniques should be used with a tripod to hold the camera steady. Timed exposures. These are long exposures from 1 second to 30 seconds, measured by the camera itself. To take a picture in this range,...
