[QUOTE="WayneF, post: 493351, member: 12496"] Mixed lighting is a big problem. Really only a couple of ways to try to handle it. You can use enough flash power to overwhelm the ambient lighting by 2 or 3 stops, and then use flash white balance (which itself varies with flash power level). Then the rest is too dim to matter much (if underexposed). Works best with a near background. Because inverse square law makes the flash power trail off, and then a distant background will still be another WB. Or if only one type of "other light", you can use color filters on the flash to make it match the tungsten or fluorescent lighting, and use WB to match it. But the filter can only match one type of other light. Sunshine is about the same WB as flash, except window light is more like shade, and more blue. In non-mixed cases, we can use a white balance card in a test picture, and set WB correction from that, but in mixed lighting, it will only match that one spot, not the rest of the area. The incandescent will be stronger some places, and the windows stronger others... So this will work better if the flash is stronger and the ambient is somewhat underexposed.
