06 Aug 2007 Nikon and capture image function from remote PC

Posted by

I just figured out another nifty feature! The D70 has two USB connection modes, “mass storage” where the camera pretends to be an external hard drive, and PTP, which is an industry standard camera-computer USB protocol. Using PTP, it does not seem possible to download the camera contents with gphoto2, as I had with my A80, but it does support the –capture-image function, which causes the trigger release to be released!

This means that I can trigger the camera from my computer! And with a simple “while” command, I now have time-lapse capability:

while true; do gphoto2 --capture-image; sleep 60; done
