Hi,

I search launching bulb capture, shutterspeed > 30s.
I've command with gphoto2, i search method with your script.

camera : Canon EOS 1000D / Rebel XS / Kiss F
gphoto2 -v
gphoto2 2.5.6 gcc, popt(m), exif, no cdk, no aa, jpeg, no readline
libgphoto2 2.5.7 all camlibs, gcc, ltdl, EXIF
libgphoto2_port 0.12.0 gcc, ltdl, USB, serial without locking

system : Ubuntu 14.04.2 LTS

script :
var gphoto2 = require('gphoto2');
var GPhoto = new gphoto2.GPhoto2();
var fs = require('fs');

// List cameras / assign list item to variable to use below options
GPhoto.list(function (list) {
if (list.length === 0) return;
var camera = list[0];
console.log('Found', camera.model);
camera.setConfigValue('shutterspeed', 'bulb' , function (er) {
console.log(er);});
camera.takePicture({
targetPath: '/tmp/foo.XXXXXX'
}, function (er, tmpname) {
fs.renameSync(tmpname, __dirname + '/picture.jpg');
});

});

example command : gphoto2 --set-config bulb=1 --wait-event=60s --set-config bulb=0 --wait-event-and-download=2s

source gphoto2 : http://gphoto.sourceforge.net/doc/remote/ [Bulb Capture]

Hi! I never tried that, but the documentation suggests to wait after activating the "bulb" config to 1.
So I'd try the following:

• set "shutterspeed" to "bulb"
• set "bulb" to 1
• wait using setTimeout() to make your exposure
• set "bulb" to 0 to end exposure
• download the picture.

Good luck :)
