Hi. I'm a yearbook photographer at my school. Everytime an assembly or school play comes around I have to go take photos of it. The problem is the auditorium has HORRIBLE lighting! The only time I can get a shot with decent lighting is by lowering the shutter speed, but considering that these are mostly performances where NOBODY keeps still, most of the photos come out with crippling amounts of motion blur. How do I get good, crisp photos in such bad lighting?
