I like taking pictures and changing them into something that resembles art. It makes the photo look more interesting. It gives it texture, substance and a story, in my opinion anyways. For example: I've attached three pictures that I took of myself with my iPad in the same night, the originals and changed them to the final the transformation below each original.
I think the finished product looks so much more interesting than the originals. The originals just looks like a person taking pictures of herself in her room but the changed photos say something else, each one has a story all of it's own.
