My dad gave me his casio ex-z40 and I took some night time pics with it. Iso was at 50, infinity focus (which i think works like crap), and auto exposure settings (i cant do it manually as far as i know :er. Most of them look a little over exposed to me and some of them have some heavy artifacts. What would be my best bet for getting better focus and less noise in the pics? I just want the pictures to be a little damn clearer and more crisp! Well, my dad upgraded his camera and gave me his old one. It's a Casio EX-Z40. It's nice but not all I want in a camera. But hell, free is better than not free! This is my campus by the way..
