I hooked up the 50D to my MacBook Pro the other day at home and found it great to see exactly how a photo is going to turn out on the big screen before taking it and was wondering when such a setup might be used and how frequently it is used, considering it's not exactly something you can roam about with.
I guess the obvious ones such as long exposure (astronomy, landscape) etc, but are there other uses? Model photo shoots?
Is it better to simply use a remote instead of hooking it right up to a computer?
