One thing you'll learn is just how convenient your digital camera really is! Before digital, I would wait up until I had several rolls of film to develop. Only after the trouble and expense of developing the film would I realize that someone had their eyes closed, another was making a face, or I just really should have framed the shot a little differently to make it just right! Preview onscreen right after the shot is a wonderful asset!
This is a great topic, and I'm really enjoying everyone's responses. Keep it up!
