Default What is a bulb?

This word is used when talking about the shutter speed, just curious to know what it is... and how it works

When your camera is set to "bulb" what it means is when you press the shutter button and hold it, the shutter will stay open until you let go. Its another way of doing long exposures.

You can do some neat things with it. Like when a car is going by, pan with your camera take the picture but hold it for like a split second longer then you usually do and let go. So say you took a 1/4th second exposure of that car going by... You might be lucky enough to have almost frooze the car, but the background will look like it was zoomin by... :P

In case you're curious, Devatch, the name dates from the days before auto flash synchronisation when the user had to open shutter, fire bulb flash then close shutter manually.
