I am new to this kind of camera, I have a Canon Rebel T3i. My cousin asked me to take some pictures of him proforming at a club. I have never used my camera at night or at a club. What should I set my camera settings on to get good shots with all the neon lights etc? I am also having trouble staying in focus, it looks like I am in focus but once I download the pictures they don't look as focused as I thought.
