I have yet to upload any images from my recent trip to Chico Hot Springs and Yellowstone but I have a few images taken with the iPhone and edited with the Tilt Shift Generator application. This app has quickly become my favorite photo app for the iPhone. In addition to digitally "shifting" an image, you can change: saturation, brightness, contrast and vignetting. All in all, it's a great app. More to come after I upload pics from my camera...
