PHSCologram (C) PHSCologram is a registered trademark for barrier-strip and lenticular autostereograms made by Chicago-based art collective (art)n laboratory. Inspired by the process oriented works of Man Ray, Duchamp and Moholy Nagy, the early process for creating PHSColograms combined sculpture with photography, resulting in a three-dimensional photograph, viewed with rear lighting.

The (art)n group Sandor formed with her peers from The School of the Art Institute in 1983 created large-scale sculptures and collaged backgrounds that were photographed 9 times at slightly different positions in a horizontal movement with a room sized camera.
These images took 30 minutes for each exposure, which were combined with a special darkroom technique to one piece of transparent, color film. A second piece of black-and- white film displaying clear vertical lines was mounted to a piece of plexiglas with the blurred, combined image mounted to the reverse. The line screen functioned as a viewing screen to interpret the transparent photograph as a three-dimensional sculpture.

By 1990, PHSColograms became a digital photographic process, by simulating the early darkroom technique with other features common to the computer graphics industry. PHSCologram imagery is constructed from sculpting objects with a computer graphics software application. These objects are painted, and placed in a scene with lighting and other special effects. Once the digital scene is complete, a series of as many as 65 images are photographed in (art)n’s proprietary art program.
