Years ago, I turned the camera display (the back of the camera) OFF while shooting...you know, the one that shows you the picture right after you shoot it. I know my cameras inside and out, every button, submenu, etc., so I know what it's going to look like when I shoot it. There isn't time to look through your images at a wedding. Sometimes with point & shoots or your phone, it's hard to know you're getting what you want. Shoot often and get familiar with your best camera...the one you have with you. Stop chimping the display, and make some pictures. The best moment often happens right after the one you thought was going to be the best. Keep the camera in your face.
