This is a photo from BB Hair Show book. I wanted to get you guys opinion on the lighting. I notice in all or most of the hair books i have seen the lighting looks like this.. The shoot I attended the guys used 2 lights with a color filter on a white sheet background.. So the color cast was on all the back and the faces as well. now sometimes the backs looked like several variations of color. I dont know how he did that.. please give me your insite on how you think this photo was achieved.
