Objects closer to the camera(s) have greater differences in appearance and position within the image frames than objects further from the camera.Historically cameras captured two colour filtered images from the perspective of the left and right eyes which were projected or printed together as a single image, one side through a red filter and the other side through a contrasting colour such as blue or green or mixed cyan.At present the excellent quality of computer displays and user-friendly stereo-editing programs offer new and exciting possibilities for experimenting with anaglyph stereo.A stereo pair is a pair of images from slightly different perspectives at the same time.Anaglyph 3D is the name given to the stereoscopic 3D effect achieved by means of encoding each eye's image using filters of different (usually chromatically opposite) colors, typically red and cyan.Anaglyph 3D images contain two differently filtered colored images, one for each eye.When viewed through the "color-coded" "anaglyph glasses", each of the two images reaches the eye it's intended for, revealing an integrated stereoscopic image.
The 3-D comic books were one of the most interesting applications of anaglyph to printing.
Recently, cross-view prismatic glasses with adjustable masking have appeared, that offer a wider image on the new HD video and computer monitors.
The oldest known description of anaglyph images was written in August 1853 by W.
Anaglyph images are much easier to view than either parallel (diverging) or crossed-view pairs stereograms.
However, these side-by-side types offer bright and accurate color rendering, not easily achieved with anaglyphs.
