BULB: Long (Bulb) Exposures
In this mode, the shutter stays open as long as you hold down the
shutter button completely, and closes when you let go of the shutter
button. This photographic technique is called “bulb exposure”. Use bulb
exposures for night scenes, fireworks, the heavens, and other subjects
requiring long exposures.

sensor or the camera’s internal components.
