hey guys, im new at the forum, my name is ricky and i really like taking photos. I recently went dslr and bought a rebel xti, but while i understand the camera very well, i have a problem that bugs me. say i want to take a portrait of myself, i put the timer, adjust the camera and move to my position. The camera then snaps the shot and almost 99% if not 100% the picture is out of focus, I understand that since I was not there when the camera first focused, it messes things up, but how can i fix this? is there a way to tell the camera to focus again or I dont know, i ran out of ideas already... thanks for your help in advance, and i look forward to posting here often.
