I shot a few dances at a recital and white balanced my camera before the recital began. After each dance, the lights would dim out completely once the performer left the stage but would re-brighten once the next performer came on. Do I have to re-calibrate the camera for every performance? The reason I ask is because some of the shots became overexposed without me noticing. The first few dances were fine but a few later it looked all washed out... What exactly happened here?
