The document discusses 3D anaglyph images and how to create them from digital photos or existing stereographic images. It explains that an anaglyph consists of two slightly offset images in complementary colors (typically red and cyan) that merge into a 3D image when viewed through colored glasses. The software and techniques described allow one to take two photos of the same scene from different angles and convert them into a single 3D anaglyph image file. A variety of potential applications and online resources for creating and viewing 3D anaglyphs are also listed.
