The revolutionary DSLR Camera Remote from onOne Software turns your iPhone or iPod touch into the ultimate remote control for your Canon or Nikon DSLR camera. You can fire the shutter, adjust camera settings, review images, and even get a live viewfinder preview – all from your iPhone! Just connect your camera to a Wi-Fi enabled computer and you’ll have un-tethered freedom to shoot and review your images remotely.

A little extreme, but an interesting perspective.
