Does Canon 550D have long exposure function? If so, please tell me where it is. (be specific)

Of course, the shutter speed can be adjusted by M and TV (the default maximum is 30 seconds). For AV files, the aperture is adjusted to 8 to 13, ISO 100 is used for night shooting, and the shutter automatically becomes longer.

In addition, you can use wired release, and then use door B (TV and M can be adjusted, after 30 seconds), and you can expose it as long as you want, but pay attention to the battery power.
