I love hipstamatic. It’s analog look is cool but I love the fact that you can shot so many shots at once with the feel of an old fashion shutter. This lets you capture a series of photos with a frame by frame animation style. The filters you can buy are unending and beautiful. I am in love right now with the Tin Type filter. It make haunting photos that look like they are from Civil War period but with modern subjects.

I also love their SwankLab app where you can add chemicals to your photos in a lab and it process the photos in a bath and hangs them to dry just like the old days.
Check out their products you will love them and make beautiful things.
