With the “Bulb” setting, or “B” for short, long exposures are possible, among other things.
With this shutter speed setting, the shutter remains open as long as the shutter release button is pressed.
When the shutter button is released, the shutter also closes and no more light enters the camera.
Exposure time must be estimated or stopped down with a clock in this mode.
Pinhole and night shots are possible with this setting.
However, it can also be used for shots with flash.
In this mode, the background blurs and the foreground is frozen and sharp.
This is a great effect especially for party photos.
