Been wanting to ask about this some time ago, cos it always leaves me puzzled.
White balance corrects the colour of the light, but does it work with camera flash? I've had some problems using white balance with flash before, examples are:
This was taken with auto WB. The whole scene is reddish from the street lamps.
I tried taking this shot with tungsten WB, but the result was horrendous! The scene was lit by tungsten bulbs.
My postulation is that if the flash is strong enough to exert colour influence, then stuffs like fluorescent or tungsten WB won't work. And if the ambient light has got more colour influence, then auto WB won't work. But til now, I still have not master the knowledge of when to use what.
Anyone can help?
