I have a Canon Rebel T3. While the shutter speed is set to bulb, can I set it that so when I press the shutter release, it will open, and then press again to close? As it is now I have to continuously hold the shutter down. It would be nice to take photos longer than 30s.
The canon 760D has bulb function that you have to hold down, so if I want to do a long exposure I have a wired remote, Shoot RS- 60E3 Wired Remote £3.59, that will lock open the shutter until you release it, if you go back and press the shutter button to close the shutter you could move the camera and spoil your shot.
