Sandwich printing

Sandwich printing, also known as negative sandwiching, is a photographic 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 juxtaposition of image elements that would not occur naturally in the world. Sandwich printing works in both black and white and color images.

Procedure

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.
