Pano is my current favorite iPhone camera app (second only to FatBooth). It’s a very minimal app that does one thing quite well: help you take multi-shot panoramic images. The UI is so clever anyone can use it. And it’s a lot of fun to take such high-resolution, well-made panoramic shots using your camera phone.
Here are some shots I’ve taken with Pano: pne of Kauffman Stadium from the nose bleeds, and one of my then-cluttered office. (And sorry, but no example shots of FatBooth pictures will be posted. My wife would kill me.)
