Hipstamatic is an extremely popular app that turns your iPhone's digital camera into an old-school single-shot camera of the past to give your images that grainy, washed-out (in a good way) retro look. The interface is a bit confusing at first, but you'll soon figure out how to switch between different types of retro film, different types of lenses, and even effects for different kinds of flashes. You can switch between each of the different variables with a swipe of your finger, with dramatically different results depending on the combination you choose before taking your snapshot.
We've reviewed image-enhancing apps here before, but Hipstamatic is the first that gives you control over which lens, film, and flash type you're using for each shot. When you're done taking the picture, the app lets you view your images side-by-side to see how each effect changes the result. Like many apps these days, Hipstamatic offers more lenses, film types, and flashes that you can purchase from within the app, so if you like what you see in this download, there's plenty more to play with.
Overall, if you want that retro look or just like to play with your images, Hipstamatic is a great choice with tons of options for those who like to fiddle with settings to make cool results.
