As neat as the little strips of photos from real photo booths are, they are a) not what I can afford, and b) not quite what I'm envisioning. I'm thinking more something like theeeese (I apologize for losing the info on where I found these images):
More fabric awesomeness. We could also provide props for extra hilarity, like my yoda backpack, our Shatner standup, paper hats, mustaches, etc. I figure we'll just set up a digital camera on self-timer on a tripod with instructions written up next to it. I'm sure we could rig up some sort of lighting, but nothing too complicated. Maybe check out some lights from my school's photo department... We could then send folks their photos with their thank you notes since I don't much feel like printing them at the reception.
I also think I want to get a flickr pro account and give out the password to our guests on the day of, so they can upload the photos they take at our wedding. I have full faith in our friends who are shooting the wedding, but it'd be fun to have extra candid shots and such.
