3. Press the left or right cross key to select a white balance setting. The white balance settings are shown with text and icons that represent different types of lights. The white balance option you set remains in effect until you change it.
If you are shooting RAW capture, a great way to ensure accurate color is to photograph a white or gray card that is in the same light as the subject, and then use it as a point of reference when processing RAW images on the computer.
For example, if you're taking a portrait, ask the subject to hold the gray card under or beside his or her face for the first shot, then continue shooting without the card in the scene. When you begin converting the RAW images on the computer, open the picture that you took with the card. Click the card with the white balance tool to correct the color, and then click Done to save the corrected white balance settings. If you're using a RAW conversion program such as Adobe Camera Raw or Canon's Digital Photo Professional, you can copy the white balance settings from the image you just color balanced, select all the images shot under the same light, and then paste the white balance settings to them. In a few seconds, you can color balance 10, 20, 50, or more images.
There are a number of white and gray card products you can use such as the WhiBal cards from RawWorkflow.com (www.rawworkflow.com/products/whibal) or ExpoDisc from expoimaging (www.expodisc.com/index.php) to get a neutral reference point. There are also small reflectors that do double duty by having one side in 18 percent gray and the other side in white or silver. The least expensive option, and one that works nicely, is a plain white unlined index card.
