Stereo Pairs
A stereo pair is a pair of images taken from two slightly different viewing angles (a left and right perspective). When the images are presented side by side and viewed with a device known as a stereoscope or stereo viewer, the brain interprets the two, fuses them, and form one three-dimensional image. It does so by creating an illusion of depth which mimics what the human eyes and brain are doing during every waking moment. The pair of images below will appear in 3D when viewed with a stereo viewer.

Anaglyphs
The classic way to create 3D images is to take two images taken from a left and right perspective, pass them through a red and cyan filter respectively, and overlap them. This creates a single image known as an Anaglyph. To reveal the 3D effect, you use special glasses (typically made of paper) with red and cyan lenses.

Chromadepth
Using the color sequence that makes up a rainbow (ROYGBIV), Chromadepth images transform 2D images to 3D images by pulling Reds into the foreground and Blues into the background. The remaining colors fall in-between Reds & Blues giving the illusion of the colors taking up different positions in space.
