Photographing for Stereoscopic 3D Lenticular Printing
There are several ways to create the illusion of three dimensions using the lenticular process but one of the most effective has always been natural 3D photography. This tutorial describes a basic workflow for creating image sequences optimized for lenticular output. Use of Red/Cyan anaglyph 3D glasses is recommended in parts.
Step 1: The Single Camera Rail System
Rail systems are commercially available or can be easily constructed. Most are manually operated. The length of the rail will determine your maximum stereo base (the distance between the far left and far right camera views) and should be related to the kinds of subjects and situations being photographed. A rail with a length of 12” will satisfy a majority of studio situations.
For this tutorial I am using a vintage Underwood wide carriage typewriter that has been modified and fit with a tripod mount. The camera is carried past the subject in 1/12” increments using a lever to trigger the space bar mechanism. With a traditional camera rail you would simply count off marks on a ruler in the increments you desire.
