I'm glad to hear you did well with it, we were just recently discussing doing this at an event over the summer. What did you charge for it? How did you get people to come over? One of my concerns was that I wasn't sure if just putting the screen up would be enough to really pull people in. Could they see the backgrounds on-site? We were thinking about trying to hook up a monitor or two to show examples of the pictures with the different backgrounds. How much editing did it take for each picture?
