I have a Canon 4000D and I would like to take some long exposure photography. It only allows shutter speeds up to 30 seconds and I would prefer to have the ability to take shots that are exposed for 1 minute or more. Is it possible? I'm OK with using 3rd party software like CHDK if I have to.

  • \$\begingroup\$ Have you looked at MagicLantern? Are you opposed to the simple method: a remote shutter release? There are simple models that simply lock the button down and fancier ones where the exposure is set in the release. \$\endgroup\$

  • \$\begingroup\$ @MichaelC Because it is about a different camera model, and people may not know the answer is the same. But I just learned that most duplicates won't be deleted, so nevermind. \$\endgroup\$

It is not possible to select exposure times longer than 30 seconds on most DSLR's.

If you want an exposure time longer than 30 seconds, you have to use "Bulb" mode. You set the camera to bulb mode, and hold the shutter button as long as you want your exposure to be. Because this is not very convenient, most people use a remote control to open and close the shutter. This can be a wired remote, a wireless remote control or a telephone app(although one could say that that is also a wireless remote).

  • \$\begingroup\$ Cheap Chinese IR remotes for 5 dollar also seem to work just fine ;) I think the 4000D also has wifi built in. Maybe a free Canon app will do the trick too. \$\endgroup\$

  • \$\begingroup\$ An IR remote is not unlikely to drain its battery real quick if used that way ... and stray infrared can be a problem with long exposures. \$\endgroup\$

  • \$\begingroup\$ @rackandboneman I always use an IR remote. I press once to open the shutter, and once to close. I use Nikon though, no idea how it works on other brands. \$\endgroup\$
