Alan, What make/model camera do you have? Is it a manual wind and rewind, or does it have a built-in motor drive? Notes: I have one camera with a double exposure switch. All the 35mm bodies are all manual wind/rewind and I've made multiple exposures with them. -- John

If you are taking two pictures on one frame, then halve the exposure time. I.E., if you meter the shot at 1/60 @f11, then shoot at 1/125 f11 and the film will be half exposed. Do the same with the second shot to get the other half exposure.

Al, There are two types of multiple exposures. One type exposes the entire frame multiple times. The total exposure should add up to what you would do if you were making a single exposure. In other words, if doing a double, use twice the shutter speed as you normally would, **or** stop the lens down by one f-stop. If you ever do this with a camera that has an auto-exposure mode, then set the film speed for twice the film speed you are using (end result is the same), but don't forget to set it back afterward. You will get a "ghost" of each image superimposed on top of the other. If you make a triple exposure, you must divide the exposure of each into thirds (to spread them evenly). Of course, you can also split the exposure unevenly to make one less ghostly and the other more ghostly. An evenly split double can be easily done with lens aperture or shutter speed. However, if you do more than two, it's usually easier to work it out with shutter speed. The important thing to remember: the sum of all of all the exposures should add up to what would be used for a single exposure. The other type of multiple exposure uses a portion of the frame for the first image, and the rest of the frame for the second one. This technique is a bit more complicated as it involves using a mask mounted on the lens to block out portions of the frame (both Cokin and Lindahl make devices for doing this). In this case expose normally as for a single image. The tricky part of doing these is ensuring the "seam" between the two halves is lined up correctly. Not that difficult, but also not recommended for a background with high detail level. A tripod and using a cable release for this is strongly recommended (so the background for each part lines up correctly). BTW, this is how you can photograph someone looking at their reflection in a mirror wearing different clothing. Makes for an interesting bridal photograph . . . bride wearing street clothes looking at her reflected image in the wedding dress. Can do same for senior photographs (street clothes and graduation gown) or a sports picture . . . party dress and softball uniform. Use your imagination for more ideas! -- John
