Can a third-party wired remote cause overexposure with the 10-second self-timer on a Canon EOS 1000D?

I use a wired RS-60E3-type remote with a Canon EOS 1000D for self-portraits, usually with the 10-second self-timer. Sometimes it seems like the shutter stays open too long and the photo is overexposed. My remote is a third-party model rather than the Canon original. Can a non-genuine remote cause this, or would the camera control shutter timing once the timer starts?

I don't see how a problem with the remote could possibly affect the shutter speed (Tv) unless you have it set to 'Bulb', in which case one press of the remote opens the shutter (after the 10 second delay) and another press of the remote closes it. When you have a specific shutter speed or aperture value set, the remote only sends a single signal that tells the camera to fire the shutter after the appropriate 2 second or 10 second delay. Once the signal from the remote is received by the camera, everything else is done by the camera. It counts down from ten seconds and then takes the picture. If you are shooting in an automatic mode or one of the semi-automatic modes, the scene could be changing while the timer is counting down and metering is being done when the lighting is different than when the shot is actually taken.

In normal shooting modes, the remote should not affect shutter duration. A wired remote like the RS-60E3 type only tells the camera to trigger; once the 10-second timer is started, the camera controls exposure time.
The main exception is if the camera is set to Bulb mode. In Bulb, one press opens the shutter and another closes it, so a sticking or locked remote could cause a long exposure.
If you are not using Bulb, overexposure is more likely due to metering/exposure settings than the remote itself. In automatic or semi-automatic modes, changing light during the self-timer countdown can lead to a different exposure than expected.
So:
- If you’re in Bulb, check whether the remote’s lock is being engaged or sticking.
- If you’re using a fixed shutter speed, the remote is unlikely to be the cause.
- Also review your exposure mode and whether the light is changing during the 10-second delay.
