Here's a small, inexpensive camera that I use all the time. The Polaroid Snap. It's an instant camera that uses a built in thermal printer to deliver 2"x 3" pictures to you in about 30 seconds. I use it to take pictures that I use as book marks but I plan on using it to take continuity pictures when I start shoot my movie. Make-up people use cameras like this and I believe wardrobe people use them too. Quick, easy, and surprisingly good pictures.
