I need advice please. Lets say I go to a wedding and shoot 200+ photos. I'm editing them and I need to put them on discs,1 for uncle Bob, 1 for aunty Jean, 1 for cousin Karen...etc etc Now I don't know who wants them as 6x4's or 5x7's or 11x14's for example. So when I come to crop them, do i crop them free size to chop off for example too much sky and let the people who want to print them out at K-mart deal with the sizes at the photo kiosk themselves?
Same thing, if I want to print a bunch of photos for myself, and I'm not sure what sizes I want while I'm editing them, should I crop free hand to get the best composition ,save them full resolutio, and worry about the 6x4 or 5x7 sizes when I go to get them printed, knowing some of the photos may be chopped to fit the specific aspect ratio at the photo kiosk?

THanks ( I hope this makes sense)
