A double exposure puts 2 separate images on the same piece of film. A danwich sandwiches 2 films together in the enlarger and prints them superimposed. In the digital darkroom we basically do "sanwiches".

Speaking from experience, the Nikon Coolpix 4500 can accomplish traditional double exposures (i.e. two separate images on the same piece of "film"). The camera simply processes two shots and merges them together, without the need for the photographer to edit the image. There are some great examples of this on DPC.

I have Arcsoft photo studio 2000

In PhotoStudio 2000:

1. Open both pictures.
2. Decide which one is going to be the primary photo.
3. Right-Click on the secondary photo, and choose "Copy"
4. Click on the primary photo to make it active again.
5. On the top of the screen, choose Layers, then New Layer.
6. Paste the new layer. It will completely cover up the primary photo.
7. Go back to the Layer menu, choose Properties.
8. Adjust the opacity to 50%, view results, & adjust as necessary.

There are shortcuts available if you have your Layers Palette available and open for viewing, but these steps should get you started in the right direction.

If you need to do it in one exposure, you can use two flashes and a long exposure. I did it using my rebel's flash and my S1's flash, both remote controlled. I simply took the shot with the rebel, it flashed, and then during the exposure I moved and remote fired my S1 flash. It would be easier if someone is around to press the shutter rather than the remotes.

I added the grain to this. After the straight on shot, I bent my back backwards and turned sideways to get my side view juxtaposed, just like Picasso painted it:



You can do this with your camera as well. If you don't have an extra flash, you can simply use a long exposure and any light you can turn on briefly twice.

Of course, if you can merge two photos in PS, that's easier than getting it in one frame per DPC rules!
