node-gphoto2
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 (npx coffee examples/server.coffee
) which runs on http://localhost:1337
and allows to change camera settings and to take pictures.
Prerequisites

Installation
After installing the dependencies, just install using:
npm install gphoto2
If it fails, please thoroughly check the output - link errors usually indicate missing dependencies. Also, the script tries to detect wether libgphoto2 is correctly installed - if this check fails although you properly installed it, please report :)
Usage
This example only shows how to achieve certain tasks, it's not meant to be executed without any asynchronous control flow logic.
var fs = ;var gphoto2 = ;var GPhoto = ; // Negative value or undefined will disable logging, levels 0-4 enable it.GPhoto;GPhoto; // List cameras / assign list item to variable to use below optionsGPhoto;
