It's an Android phone app called Kultcamera. If you pay a small fee you get 4 different "cameras", each with a wide choice of film and lens simulations. I've rediscovered it after having used it a couple of years ago, and it can produce some really nice results. That particular image uses the "Liana F+" camera, "Dorian Gray" film, and the "Dirty ol' bastard" lens.What's this filter called? I like the look and am amused by the names.
