An Apple iPhone ad that aired in April claimed, "Every day, more photos are taken with the iPhone than any other camera", and I can believe it. Not only are there are a boatload of iPhones in the wild, there are a huge number of apps that enhance and improve on Apple's default camera app making photography more accessible, more creative, and more social. This is a collection of some of the best and most interesting apps available.
Photosynth (free) from Microsoft "stiches" together multiple photos in realtime to create interactive panoramas. While it's simple to use I've found that making really good panoramas with Photosynth is a bit hit-or-miss as the app doesn't handle brightness changes well and oftens make mistakes in blending the images.
