I am a bit puzzled about magic filters. I must say I have not used any so far, but I do not understand the point. I mean, which is the advantage of applying a filter to block/attenuate some of the incoming light frequencies? Would not it be easier and more accurate to act in post process on the raw file by balancing the color channels (or doing white balance)? Furthermore each magic filter is designed to work well only at certain water depth/light intensity/water colour... Or did I miss the whole point?
Anybody could explain?
