bulb mode

Bulb mode on a camera allows you to keep the shutter open for an extended period, from fractions of a second to several minutes, by manually controlling when it opens and closes. This setting is useful for capturing long-exposure shots, such as night scenes, star trails, or light painting, where more light needs to be collected over time. In bulb mode, the camera's shutter remains open as long as you hold down the shutter button, giving you precise control over exposure duration. It's especially beneficial in low-light conditions or creative photography that involves capturing motion over extended periods.
