indefinitely—or until 30 minutes have passed. However, even if the camera has shut itself off, if the power switch remains in the On position, you can bring the camera back to life by pressing the shutter button halfway, or the DISP, Playback, or Set buttons.

SAVING POWER WITH THE Rebel T2i

There are three settings and several techniques you can use to help you stretch the longevity of your T2i's battery. The first setting is the Review time option described earlier under the Shooting 1 menu. That big three-inch LCD uses a lot of juice, so reducing the amount of time it is used (either for automatic review or for manually playing back your images) can boost the effectiveness of your battery. Auto power off turns off most functions (metering and autofocus shut off by themselves about six seconds after you release the shutter button or take a picture) based on the delay you specify. The third setting is the LCD Brightness adjustment described below. If you're willing to shade the LCD with your hand, you can often get away with lower brightness settings outdoors, which will further increase the useful life of your battery. The techniques? Use the internal flash as little as possible; no flash at all or fill flash use less power than a full blast. Turn off image stabilization if your lens has that feature and you feel you don't need it. When transferring pictures from your T2i to your computer, use a card reader instead of the USB cable. Linking your camera to your computer and transferring images using the cable takes longer and uses a lot more power.

Auto Rotate

You can turn this feature On or Off. When activated, the Rebel T2i rotates pictures taken in vertical orientation on the LCD screen so you don't have to turn the camera to view them comfortably. However, this orientation also means that the longest dimension of the image is shown using the shortest dimension of the LCD, so the picture is reduced in size. You have three options, shown in Figure 3.41. The image can be autoro-tated when viewing in the camera and on your computer screen using your image editing/viewing software. The image can be marked to autorotate only when reviewing your image in your image editor or viewing software. This option allows you to have rotation applied when using your computer, while retaining the ability to maximize the image on your LCD in the camera. The third choice is Off. The image will not be rotated when displayed in the camera or with your computer. Note that if you switch Auto rotate off, any pictures shot while the feature is disabled will not be automatically rotated when you turn Auto rotate back on; information embedded in the image file when the photo is taken is used to determine whether autorotation is applied.

Choose autorotation both in the camera and on your computer display (top); only on your computer display (middle); or no automatic rotation (bottom).

Format

Use this item to erase everything on your memory card and set up a fresh file system ready for use. When you select Format, you'll see a display like Figure 3.42, showing the capacity of the card, how much of that space is currently in use, and two choices at the bottom of the screen to Cancel or OK (proceed with the format). A yellow-gold bar appears on the screen to show the progress of the formatting step. (The optional low level format invoked with the Trash button is a slower, but more thorough reformatting that can help restore a memory card that has picked up some bad sectors that aren't locked out by the normal format step.)

File Numbering

The Rebel T2i will automatically apply a file number to each picture you take, using consecutive numbering for all your photos over a long period of time, spanning many different memory cards, starting over from scratch when you insert a new card, or when you manually reset the numbers. Numbers are applied from 0001 to 9999, at which time the camera creates a new folder on the card (100, 101, 102, and so forth), so you can have 0001 to 9999 in folder 100, then numbering will start over in folder 101.

The camera keeps track of the last number used in its internal memory. That can lead to a few quirks you should be aware of. For example, if you insert a memory card that had been used with a different camera, the T2i may start numbering with the next
