I've downloaded two new apps for my iPhone 4S (Camera + and Afterlight), and have been experimenting with them this weekend. There are so many filters for color, texture and lord-knows-what-else that it can be intimidating at first; I suppose I should just read the insturctions, but come on, it's way more interesting (ahem, time-consuming) to just try every. single. filter. on each picture! Below is a slide show of my weekend creations (hello very green cat!).  What apps do you use for your photos?
