Notes on Nikon cameras

* If you trigger the shutter with the tether bar capture button, the image must finish downloading before another photo can be captured. Triggering a capture with the shutter release button on the camera does not have this limitation.
* Images do not save to the CF card. They are only downloaded to the computer.
* D200 is not supported on Windows.
* Only one Nikon camera can be attached at a time.
* Windows 7, Windows Vista, and Mac OS X 10.6 are not officially supported for the D3x, D90, and D5000, but they can still work.
