Some free Software that might interest Nikon owners.
It allows you to connect your camera to your computer for tethered shooting.
I've had a quick play and it seems pretty good. Simply plug it in via the USB cable and you can remotely take control of the camera.
All the main functions seem to be adjustable - Aperture, Shutter Speed, ISO, White Balance etc. Live View is supported, as are things like Bracketing.
Haven't tried it with a mobile, but I'm pretty impressed with the computer control side of things thus far, especially as I was looking at buying Nikons own software for doing the same thing...
