I rode to Mt. Diablo today so I thought I'd play with my new iPhone 5's panorama feature.
There is no stitching the photographer needs to conduct. You just pan the iPhone as indicated on screen and this is what you get. This is pretty much straight out-of-camera. I took out a couple of tiny spots where birds were flying (which ended up looking like OOF sensor dusts). No other editing except the resizing.
This is 100% crop from far left size of the photo. You can see my orange Triumph in there.
The original image imported to iPhoto from iPhone was
10784 x 2376 px, 17.1 Jpeg.
Just for fun I thought I'd share...
