Backlighting Existing Photo Prints

If you have a light table, you can use it to produce some interesting effects on existing printed images. The idea is to place your image on the table and photograph the image again - with the back light from the table. The photo print paper I use is thin enough to let some light through. I have used a texture print below the main print for a different look. Also, you can use multiple prints below the main print to block off a particular area on the main print for highlighting. You can come up with some interesting effects using this method.
