I tried to send an e-mail to Canon, and when I clicked on "Submit", it failed to connect. So, I am posting my inquiry here. This message does not concern an "issue" per se, rather a technical / operational inquiry. I am planning on making my initial forays into astrophotography / light painting and have a couple of questions on the Bulb setting / Intervalometer. I also invested in a Neewer digital timer / remote. If I use the Bulb setting on the and use either the RC-6 or RS-60-E3 remote cable, and I set the Bulb timer, let's say for 25 seconds or so. When I press the button on either of these devices, it will open the shutter. My question is whether when the 25-second time expires, will the camera automatically close the shutter on its own - or - do I have to do that manually. I did order a stopwatch, by the way, in the event the camera will not close the shutter automatically after the expiration of the 25-second time period. Likewise, if I would use the built-in intervalometer and set it for only one photograph and a 25-second exposure length, would the camera shutter automatically close after the 25-second time period passes, or does that have to be done manually? I would really like to be able to run into the picture and light certain areas with a flashlight for light painting purposes, and it would be very helpful to know whether the camera is going to automatically close the shutter on its own using the Bulb setting, or whether I would have to use my stopwatch and run back to the camera to press the button on the remote within my chosen exposure time length. I hope this makes some kind of sense. I was unable to make this determination through reading the Manual or online research.
