Please could someone explain Bulb Exposure and how it works. I have just bought a Canon EOS 300. Thanks David

In bulb mode (the "bULb" setting in manual metered mode) the shutter stays open for as long as you keep the shutter release pressed. This lets you take long exposure photos - longer than 30 seconds. So if you want to take long nighttime photos (eg: photos of roads where cars are just streaks of white and red light), this is how you do it.

Obviously you risk camera shake if you sit there with your finger on the shutter release, so it's best to buy a wired remote shutter release, which you can plug in in the side. If I recall correctly the EOS 300 supports such a wired release, but does not support a wireless infrared remote. (only the Japanese version of this camera supports wireless)

Bulb is useful when the object so dim that the slowest shutter speed of the camera cannot yield proper exposure eg,shooting night scene,fireworks,waterfall or other special effects. It is executed in EOS-300 (perhaps other eos)when u switch to manual exposure mode and set to BULB. Use of remote release and tripod are strongly recommemded to avoid any shake.
