Set Custom White Balance Settings on Canon Rebel T3 Series Cameras
If none of the preset white balance options on your Canon Rebel T3 or T3i produces the right amount of color correction, you can create a custom white balance setting. To use this technique, you need a piece of card stock that’s either neutral gray or absolute white — not eggshell white, sand white, or any other close-but-not-perfect white. (You can buy reference cards made just for this purpose in many camera stores for under $20.)
Position the reference card so that it receives the same lighting you'll use for your photo. Then follow these steps:
Set the camera to the P, Tv, Av, M, or A-DEP exposure mode.
You can’t create a custom setting in any of the fully automatic modes. (You can, however, select the custom setting you create when you record movies.)
Set the White Balance setting to Auto (AWB).
Set the camera to manual focusing.
Frame the shot so that your reference card fills the center area of the viewfinder.
Make sure that at least the center autofocus point and the six surrounding points fall over the reference card.
Make sure that the exposure settings are correct.
Just press the shutter button halfway to check exposure. If necessary, adjust ISO, aperture, or shutter speed to get a proper exposure.
Take the picture of your reference card.
The camera will use this picture to establish your custom White Balance setting.
Display Shooting Menu 2 and highlight Custom White Balance.
The image you just captured should appear in the display, along with a message that tells you that the camera will only display that image and others that are compatible with the custom white-balancing option. If your picture doesn’t appear on the screen, press the right or left cross key to scroll to it.
Press Set to select the displayed image as the basis for your custom white balance reference.
Press the right or left cross key to highlight OK and then press Set.
The message tells you that the White Balance setting is now stored. The little icon in the message area represents the custom setting.
Press Set one more time to finalize the custom setting.
Your custom White Balance setting remains stored until the next time you work your way through these steps. Anytime you’re shooting in the same lighting conditions and want to apply the same white balance correction, just press the WB button (top cross key) or use the Quick Control screen to access the White Balance settings and then select the Custom option.
