multiple exposure, how do I?

[Doug Spencer]

I have a camera that is multi exposure capable. I can trip the shutter,
advance the crank, and it will stay on the same frame - for release of
shutter.
How do I do the multiple exposures that i see some wedding photographers do?
Do you cover half the lens with something, trip the shutter, then cover the
other half and trip it again?

ANY tips on multi's will be greatly appreciated

You can cover half the lens or take the first picture who has a piece very
dark. Take a second picture bright where the first is dark and dark where
the first is bright.

Most wedding photographers I know will take the smaller exposure (usually a portrait) in a studio setting with a lens mask. At the church the other exposure is made keeping the first area of coverage in a darker area of the second image or in a few cases masking the lens with a filter in this area. The problem with using masks is that they will leave a hard edge on the ege of the masked area. Many photographers simply tell the printing lab what they want done and leave it up to them to do it using 2 separate negatives. By far the easiest method now is to convert the negative to a digital file and use an editing program likew Photoshop and have a digital laser print made. Another problem with multiple exposure is that although you would think the film speed would remain constant for both exposures, it usually doesn't. Under controlled studio conditions, I've done as many as 6 exposures on one frame (which I will NEVER do again) and depending on the film, I may add as much as a full stop extra to get additional exposures to look correct. It takes a lot of practice but with luck you can end up with a good image. Again, I think digital IS the way to go for this.
