Why purchase filters when you can white balance?

[Josh66]

Because you can't accurately white balance if there is mixed lighting. (mixed lighting = multiple light sources of differing color temperature in the same scene.)

So let's say you have daylight and incandescent mixed in one shot........... what filter would you use?

Yes, very interesting question... I would like to know as well, since daylight/incandescent is a very common mixed lighting scenario...


(I always thought that a gelled flash was the only solution, but apparently there is some filter that can do it too ... as this is being used as an example of a time when you should buy the filters...)
