Today I purchased the True HDR photography app for my iPhone. It came after a conversation with my girlfriend about making a long exposure app (we’re going to a fireworks display tonight). True HD is a high dynamic range app. It takes 3 pics and merges them together to create a HDR image.
One thing I’d like is if there was a way for the app to take as many steps as you want but that might not be doable because of processing problems. Below are a couple of sample images.
