Some gPhoto2 utilities (Linux scrips) to help you control your DSLR from the command line. Mainly thought to be used with Nikon DSLRs

• Capture single photos and movies (by giving the duration in seconds)
• Download all the photos skipping all the already-downloaded photos. Also with sync: let gPhoto2 download all photos continually while they are being captured (ideal for intervalometers).
• Download only the latest photo
• Move the focus point
• Live view (VLC)
• Intervalometer mode (shooot and m-shooot). Also in Bulb mode!
• Manipulate aperture, ISO, shutter speed, viewfinder, automatic dark setting
• Get battery level, focal length and image format from the camera
• Get a summary of all the camera config
• Look for DSLRs
• Convert RAW images (UFRaw)

Without having to remember gPhoto2 commands!

You'll be asked interactively, so you don't have to remember them!
