By now you all know that there are a ton of photo editing an manipulation app available for iOS devices. One of those apps is Camera+ a $1.99 great iPhone app that I got way back when I had my iPhone 3GS, and thought that I would never need to use it when iPhone 4 comes out, was I so wrong.
Using Camera+ on any iPhone including the new one is simply a pleasure, since you can edit and retouch your images using the apps light box feature. Both images included in this post have been edited using the app to get that HDR effect, on the above image, and a vintage effect on the one bellow. You can get Camera+ from the iTunes App Store.
