There are a bazillion IPhone and Android camera apps to manipulate your images with. One of the best camera apps we've used is Hipstamatic which, we're sure, you've already discovered.
Hipstamatic allows you to select multiple film/ lens combos which will give you hundreds of options to choose from. This selection below (shot around Dickerman Prints this morning) uses just one B/W combo we really like. Download the app to find your favorite combo!
