Im going to photograph a singing group this Sunday evening. Its at a motel in the ball room. Now the problem is the liting. There are over head can lites that put off a yellow/orange cast along with 4" flourescent lites that are of a mix daylite and yellowish.orange color. I did this once beore and it was a disaster, but was able after some work git them back to some kind of reality. Iam using the Canon rebel xt, any advise on settings would be apprecuated, would a strobframe be of any benefit,?
