The other day I discovered the Photosynth app for iOS. Currently free, and from Microsoft, this handy dandy little photo app makes panoramic pics so simple. You just tap the screen, and move the iPhone/iPod/iPad around. The app take pics automatically, and then stitches them together into a virtual view. Inside the app and on Photosynth.net website, you can explore them in quasi virtual reality. Or you can crop a version and post it to Facebook.
Above is an image I quickly took of a rehearsal for our Easter production. It makes the Worship Center look huge. I find that I get best results when I manually capture the images. Sometimes the app gets confused, and needs a bit of help. You can only upload to Facebook or Photosynth from within the app, but the images are saved to your camera roll. So you can leave the app and post at will.
For free, hard to beat this fun little photo app.
