[QUOTE="WayneF, post: 429308, member: 12496"] Direct bright sun is pretty much a constant. But... Sunrise and sunset and cloudy is not. Shade and Cloudy varies with sky. There are many colors (and bulb types) for incandescent (regular ones, not speaking of colored bulbs). Fluorescent is a big mixed bag. Even if we knew bulb type, same type varies considerably. With bulb age if nothing else (but there is plenty else). Flash color varies with power level. etc, etc. If you think it is always correct, you are far from critical. The crude camera settings (independent of scene) are the problem, not the solution. If WB were easy and obvious, no one would ever discuss it. The easy way (fast and good) is to include a known neutral white color in the (test) image. The raw software is quite good to identify a color cast in a known white area, and can easily fix the image(s) to be perfect color. Of course, we might still prefer to hit it with Vivid or something, but it does not have to have a color cast. [/QUOTE]
