How to make an anaglyph image

An anaglyph is an image where color is used to multiplex the left-eye and right-eye view into a single image space, where a pair of anaglyph glasses is used by the audience to decode and fuse the stereoscopic image.  In the USA, typically the left eye views through a red lens, and the right eye through a blue or cyan lens.  But the “standard” is not set in stone worldwide.  In Europe that configuration is sometimes reversed, with red over the right eye, and there are also other anaglyph colors sometimes in use, such as yellow and blue.

Here I will teach you how to make a “standard” red/blue anaglyph, as is most commonly found in USA, in comic books and of course all over the web.
