onOne has released their DSLR Remote application for the iPhone, which allows iPhone users to control their DSLR cameras (Canon only) wirelessly using the iPhone from afar.
The Canon DSLR camera needs to be hooked up to a computer (via USB) such as a netbook, and the DSLR Remote app on the iPhone is able to communicate with the computer wirelessly. The user can then use the DSLR remote app to control the camera such as controlling the shutter speed, aperture and white balance.
Furthermore, the application can be used to live stream the camera’s Live View Feed onto the iPhone, so the user can have a real-time look at what is in the frame. This iPhone DSLR app will be available on Apple store with an introductory price of $10 and will jump to $20 once the introductory period is over. It also has a lite version which is restricted to the capability to snap photos only. Again, this DSLR app is only meant for controlling Canons. Visit onOne for the compatibility list.
