A Node.js wrapper for libgphoto2. Useful for remote controlling of DSLRs and other digital cameras supported by gphoto2.
The included test application currently allows you to
- receive a live preview of your camera (if supported). Tested with an EOS 550D on a 2010 iMac at ~17 fps using Chrome (Safari doesn't work and FF is slow as hell).
- query a list of available configuration options
- query the values of specific configuration options
The test suite can be run using npm test. There's also a small test application in test/test-server.coffee which runs on http://localhost:1337 and allows to change camera settings and to
take pictures.
