I'm surprised no one seem to mention slides.
I read all the posts but not 100% of each, but I didn't see anyone mention slides. I took two rolls of a family wedding a few weeks ago on slides and one roll of prints. Last week I went to my sisters house (she wasn't at the wedding) and set up the projector and screen and we looked at slides. Yes, you can take slides with a MF but the projectors are rare and expensive. (Actually 35mm projectors if you can find them are expensive too.) I like looking at a 3 foot by 4 foot picture and that fact that you can show it to several people at the same time. I sent scanned copies on a CD to the bride, but nothing compares to the color and the wow factor of seeing that picture blown up to the size of a table. Ric.
P.S. I have never seen a LF slide projector.
