Use White Balance Auto Bracketing

• RepairSurge Auto Repair Software

Given the range of indoor tungsten, fluorescent, and other types of lights that are available, the preset white balance options may or may not be spot-on accurate for the type of light in the scene. Alternately, you may prefer a bit more of a green or blue bias to the overall image color. With the XSi/450D, you can use White Balance Auto Bracketing to get a set of three images, each a slightly different color bias up to +/- 3 levels in one-step increments.

White Balance Auto Bracketing is handy when you don't know which color bias will give the most pleasing color, or when you don't have time to set a manual white balance correction (detailed next in this section). The white balance bracketed sequence gives you three images from which to choose the most visually pleasing color. If you're shooting JPEG capture in Creative Zone modes and use the Standard, Portrait, or Landscape Picture Style, White Balance Bracketing can be a good choice to reduce the amount of color-correction time you spend on the computer.

Note

White Balance Bracketing reduces the maximum burst rate of the Rebel XSi/450D by one-third.

To set White Balance Bracketing, follow these steps:

1. Press the Menu button, and then press the left cross key until the Shooting 2 (red) menu appears.

2. Press the down cross key to highlight WB SHIFT/BKT, and then press the Set button. The

WB Correction/WB Bracketing screen appears.

3. Turn the Main dial clockwise to set a Blue/Amber bias, or counterclockwise to set a Magenta/ Green bias. As you turn the Main dial, three squares appear and the distance between them increases as you continue to turn the dial. The distance between the squares sets the amount of bias. On the right side of the screen, the camera indicates the bracketing direction and level under BKT. You can set up to +/- 3 levels of bias.

4. Press the Set button. The

Shooting 2 (red) menu appears.

5. Lightly press the Shutter button to dismiss the menu.

6. If you're in One-shot drive mode, press the Shutter button three times to capture the three bracketed images, or if you're in Continuous drive mode, press and hold the Shutter button to capture the three bracketed images. As you shoot, the White Balance icon on the LCD and in the viewfinder flashes until all three bracketed images are made.

With a blue/amber bias, the standard white balance is captured first, and then the bluer and more amber bias shots are captured. If magenta/green bias is set, then the image-capture sequence is the standard, then more magenta, then more green bias.

Note

You can combine White Balance Bracketing with Auto Exposure Bracketing. If you do this, nine images are taken for each shot. Bracketing also slows the process of writing images to the SD (Secure Digital) card.

White Balance Bracketing continues in effect until it is cleared or the camera is turned off.
