Set camera to PTP mode, not USB mode

For your Nikon DSLR to work with the DIYPhotoBits.com Camera Control script it needs to be in PTP mode, not in USB mass storage mode.

• D700 : Only supports PTP mode so nothing to change
• D300: Setup Menu / USB / MTP/PTP
• D90 : Not necessary as D90 is always in PTP mode, it doesn’t support USB mass storage mode

Here is a video I made that shows you how to do it.
