Hi, I am in a pre college program, and tomorrow, I have an assignment of taking pictures in this museum with very low light. Now since I will be going with a class, and constantly moving, and id prefer to stay away from the tripod. I defiantly do not like the look that a on-board flash gives. Im working with a Cannon Rebel T3i, with no external flash. ONLY HANDHELD, so slow shutter speed is out of the question. I will also be shooting in FULL manual mode. I need these images to be as sharp as close as I can possibly get with just my camera. My ISO is set at 100... I feel if i turn it way up, the noise will be very visible, and if i turn it down to low, it will be too dark. Any possible suggestions? Thanks guys!
