Creating 3-D Red/Blue Anaglyphs from Photographs
The ability to create 3-D images is currently a hot marketing tool as new technology has sparked interest in three dimensional media. One of the oldest and least expensive methods to create and reproduce a 3-D image is the anaglyph. Anaglyphs are a method of encoding a three-dimensional image in a single picture by superimposing a pair of pictures. The anaglyph consists of a left and right image encoded to create the perception of depth in the image. Anaglyphs are not difficult to create, however creating good anaglyphs is a craft. A poorly made anaglyph can make the viewer feel uncomfortable. The most important and difficult part of the anaglyph is creating the original photographs or images. The originals should have depth in the image; otherwise the anaglyph will not exhibit much 3-D effect. Objects in the foreground of the original photographs will create the appearance of depth or accentuate the 3-D effect.
