iPhone TimeLapse Test from digitalurban on Vimeo.
Here's a fun application. TimeLapse [App Store link] uses your iPhone's camera to take photos at regular intervals. You can have one photo snapped as infrequently as every 24 hours, or as often as every 10 seconds, which is about as fast as it can snap and store a photo. After you've collected all of your photos (I told it to stop after 300), you can easily dump them into iMovie or QuickTime Pro and make a simple time lapse movie. Neat!
You can set a delay before it takes a shot, which means you can also use TimeLapse as a timer to allow the photographer to get in the frame. Additionally, it could work as a rudimentary surveillance camera. While it's running, a display lists when it started, the time of the last picture taken and the approximate time of when it will stop.
Here are a couple of things I learned while briefly playing with it this afternoon. First, mute your iPhone before beginning or you'll have to hear the camera's "capture" noise over and over again, which is kind of annoying. Also, enable Airplane Mode or an incoming call will interrupt your photoshoot.
For $0.99US, TimeLapse is fun.
