Why does my Canon T3i start another exposure when I use a wireless remote in Bulb mode?

I’m using Bulb mode on a Canon T3i for night long exposures with a wireless remote. I press the remote once to open the shutter and again to close it, but after closing the exposure the camera immediately starts another one. If I keep using the remote, it keeps ending one shot and starting the next. The only way to stop it is to press the camera’s shutter button. What could cause this, and how can I prevent it?

If you are using the RC-6 wireless IF remote, the possibility is that its being interrupted when you push it to close the bulb mode, the battery is dying on the remote (not likely if new but possible), or its being pressed for too long to close the shutter and then your camera thinks its time to start a new picture. try setting the camera to single shot and try again ensuring you have a clean line of site to the IF receiver on the handle of the camera.
personally, I would recommend just getting the wired trigger for bulb mode because you can ensure shutter control better. IE http://www.ebay.com/bhp/canon-rebel-t3i-remote

This is usually a remote-control issue rather than a camera fault. In Bulb mode, each remote signal can act like a shutter press, so if the camera receives an extra or prolonged signal when you try to close the exposure, it may interpret that as a new press and start another shot.
Likely causes include:
- holding the remote button too long
- an interrupted or inconsistent IR signal
- weak remote battery
- drive mode not set to single shot
Try these steps:
- set the camera to single-shot drive mode
- make sure you have a clear line of sight to the camera’s IR receiver
- press the remote button briefly rather than holding it
- replace the remote battery if needed
For Bulb exposures, a wired remote is often more reliable because it gives more consistent shutter control and avoids line-of-sight IR issues.
