I'm doing a beginners photography course and our assignment this week is night photography. Love your idea but what do you mean B exposure? I've not heard that term before.
"B" stands for "Bulb" and is a hangover from the days when a camera's shutter was held open by squeezing a bulb of air attached to the shutter release by a tube. The shutter would remain open until the bulb was released. These days it's done differently but the terminology remains the same! Confusing to you youngsters, I know, but to us old f*rts in this digital age it's one thing that we at least understand!

To use Bulb on your E500 select M (manual exposure) on your mode dial. Turn the command dial clockwise to increase the exposure time. When you go past 60 seconds (the maximum electronic expoure time the camera is capable of) you will see BULB appear at the top of the LCD. Now, if you press the shutter button and keep it pressed the shutter will remain open until you release the button.

If you buy a remote release (RM1) you can use this to hold the shutter open rather than keep pressing the shutter button, which is more convenient if you need to move around firing flashes or using a torch to "paint" with. You will need to have your camera on a tripod, of course, whichever method you use.

There may be a limit to how long you can keep the shutter open (I can't remember) but if there is it will be a long time. Make sure you have a fully charged battery loaded because battery power is still needed to hold the shutter open even though you are doing it manually.

In this mode the camera is not controlling the exposure for you so it's a bit hit or miss and you'll just have to experiment. At least with digital you can see the results instantly and shoot again if neccessary. To keep a track on what you've done use your watch to time the exposures. Then, if you've used an exposure of, say, 2 minutes and it looks a bit too dark, try it again at 4 minutes (a one stop increase in exposure). If it looks too light shorten the exposure time to 1 minute (a one stop decrease in exposure). Of course, you may find you need more radical adjustments than these examples, but it is a matter of trial and error. It's best to select a large aperture (small f number) to prevent exposure times becomming too long, at least to start with. Do it methodically like this and I'm sure you'll soon get the hang of it.

Have fun!
