Thanks, Abstract and RK. The red tone of the light on stage was much more intense and more magenta; for this picture, I did not like this, so I have changed the color balance slightly; I am not quite content with the result yet I think it is an acceptable compromise between balancing for most natural skin tones (this would make the costumes look boring) and leaving color in its original state. Converting to B/W would solve the problem, but I wonder whether this would convey the mood of this performance. I don't think I have posted exactly this picture before but you remember right, I certainly have posted some other shots from the same event before.
