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.
