lenticular process

While these projects are often generated from computer graphics, the lenticular process doesn't inherently rely upon microchips or computers.

Keller-Dorian cinematography was French technique from the 1920s for filming movies in color, using a lenticular process to separate red, green and blue colors and record them on a single frame of black-and-white film.

Throughout the 1950's and 1960's, the lenticular process was used to produce sublime and ridiculous images, from flicker-image novelty rings and animated postcards of a winking girl to a 3-D devotional picture of Jesus.
