Just to get a feel for what other people do, what mode (PSAM) is usually used for general shooting, or does it depend solely on the situation. For example, I am taking some shots of a family backyard party, and I usually just put it on auto because I dont know what mode to set it on, and then what to adjust. It just seems as though asjusting the shutter and app. takes a long time. Its a DSLR if that makes a difference to the answer.
