I'm going to be the photographer at a high school dance this weekend, and while I'm doing portraits, I'll be having my assistant wander around the dance taking pictures with my Nikon WiFi enabled point-and-shoot. The camera automatically sends the pictures it takes back to my laptop, which saves them to a certain folder, and what I'd like to be able to do is have the pictures automatically show up on screen as soon as they're taken, with a dissolve transition between each photo. Can anyone think of a good way of going about doing this? I'm thinking something involving folder actions and Applescript.
