I have a d50. I'm doing pretty okay with it but havent really figured out all the controls. So here is my problem. My camera is taking small pictures. I want to increase the size of them. It's not taking low resoloution, it's just taking small pictures so when I want to get them printed out they are tiny and if I try to increase the size it makes them look grainy. If any of you are particularly familiar with this could you please give me a step by step tutorial of what to do to change this. I'm not having much luck. Thanks!
