The B setting stands for "bulb" and stems from days of yore when photographers sometimes used a small air tube connected to a squeeze bulb that they held in their hand. The camera end of the tubing was connected to the shutter. If they squeezed the bulb and held it, the air pressure activated the shutter which would stay open until they relaxed their grip on the bulb. By this means, they could open the shutter for longer periods of time than what the camera was capable of doing on its own. Modern cable releases are connected to the shutter button to perform the same function.
Most cameras don't have a dedicated shutter speed longer than thirty seconds. If you wish to take exposures longer than that, use the bulb function ('B' on most cameras). Bulb allows the shutter to stay open as long as the shutter button is held down. Get a locking cable release, switch camera to bulb, and you can take any length exposure you want.
It means "bulb", and is a shutter speed setting that will allow you to keep open the shutter by depressing the release and holding it down. In actual fact, it would be pointless in most cases to do this using your finger on the release as you will cause camera shake and image blurriness. A cable release and tripod is the norm. The word bulb comes from the fact that the original releases used for this were made from tubing to transmit air pressure caused by squeezing a rubber bulb for as long as you wanted the shutter to remain open. I believe these pre-date the invention of wire cable that was thin and stiff enough to replace the air pressure method.

The slower the film -- that is, the lower the ISO rating -- the longer the shutter must stay open at a particular aperture (F-stop). In low light with slow film, the shutter may have to stay open too long for the camera to be hand-held without noticeable camera shake, even with cameras with optical image stabilization.
An automotive engine's camshaft rotates at A. the same speed as the crankshaft. B. one-quarter the speed of the crankshaft. C. one-half the speed of the crankshaft. D. twice the speed of the crankshaft.
The minimum speed, i.e., the slowest the shutter will cycle, is B. The shutter will stay open for as long as the shutter release button is depressed. You can't get much slower than 'not moving'.

The Sony Cyber-shot DSC-H20/B Digital cameras smile shutter mode automatically captures an image when your subject smiles without having to press the shutter.
its what one would call a B and B setting...

Junie b jones is not a crook... What is the setting?
Pinhole was a slang term for A. a primitive type of camera with a very small aperture, giving maximum depth- but requiring much light, and B. this still in use- the smallest , and thus the deepest in depth of field aperture of any given camera or lens. My most modern Nikon F-80 has a preselected F/32 pinhole setting ( coded in as M) on the modal dial) this is great for distance shots of skyscrapers and the like on bright days only! Photo sensors will shift to a brighter aperture if there is anadequate light- such is progress. l25 ( shutter speed) and F-32 can work wonders with buildings.
