What are the white balance options?
There are four white balance modes: Auto, Indoor, Outdoor, and One-push. The first one, the default, is automatic white balance like in most consumer cameras. The next two are fixed color-temperatures settings for sunlight and incandescent light. The last is manual: you point the camera at a white surface and (after holding the button down for a few seconds) it sets that color to white. The settings are accessed through a menu. I normally use auto-balance; some people emailed to say that the white setting drifts with time in auto mode, so they use manual mode instead.
