One of the things that struck me about this photograph is how you can manipulate the iPhone while you're taking a photo. I shot this photo in landscape mode, by tilting it backwards prior to rotating it, which ended up giving me a portrait result. I think that's kinda neat.
Also, if you'll notice the depth of field. I think I might try playing with the iPhone's DOF, albeit not its best feature, but it is there, and I think I might be able to start to come up with some neat results given the proper conditions.
