Sandwich printing, also known as negative sandwiching, is a technique created by combing two negatives or slides into the film carrier of the enlarger and printing on one sheet of paper as one image. This technique is generally used to create a juxaposition of image elements that would not occur naturally in the world. Sandwich printing works in both black and white and color images. When film negatives are used one image will appear in the shadows of another image. This occurs as a result of the shadow areas being less dense than the highlight areas of a negative. The more contrast and underexposed the shadows the clearer the image will shine through the other negative. The opposite occurs when using slides, one area appears in the highlight and pale areas of the other image.

This technique of printing is generally mastered after a lot of trial and error with each individual photograph. When working with black and white for the most realistic look choose negatives with similar levels of contrast. Sandwich printing is porbably one of the hardest things to master in photography. Also when doing a test strip for sandwich print do every 4 seconds

[edit] Multiple printing

Multiple printing is a term used to describe the overprinting of one image onto another. One way to do this is by simply exposeing one image onto an already exposed sheet of black and white paper. You can do this with as many images as you would like, however overcrowding can create a negative mood on the picture. It is also important to make sure that the exposures and film brand name are similar to one another. This technique also generally uses things called dodgers to hide certain areas of photos from being exposed.
