bulb (slow shutter)

if you have DSLR camera set you camera mode into Manual setting then turn your shutter dial till it will go to bulb... using bulb means you are making your exposure longer to get more light.

For you to do this, your camera must have a featuer that you can adjust the shutter speed manually. Usually, you set it to 5 secs or more so it will take as much as light that it can take and make the whole scene lighter and those light source like candles and bulbs with glow.

Bulb mode is very useful for taking shots of fireworks at night, or for capturing 'light-streams' when shooting city night scenes. The 2 main pieces of kit needed for good bulb photos are a tripod and a remote shutter release, these are essential to avoid camera shake. For good photos, set your camera to manual mode, open the apeture to as clos to 'F1' as you can, and set the shutter speed to 'bulb'. With canon DSLRs, the first press of the shutter starts the picture taking, the second press stops it. If you are experimenting with photographing fireworks, use a piece of black card in front of the lens to block the light in between each firework goin-off. The best piece of advice though, has to be, experiment. You will take loads of shots before you perfect the technique of bulb photography.
