The Color-Difference Blue-Screen Traveling Matte Process is a technique used in motion picture special effects production to composite two or more scenes into one. A complaint often made against the process is that boundaries between the composited images are often 'harder,’ i.e., there is a sharper transition between the image and their surround. Because this is visible, it is objectionable. An attempt at duplicating the process, so the boundaries could be analyzed using microdensitometry was made. Failure at key steps in the process rendered results inconclusive, but raised several interesting questions of the process. Also, a simple technique was fabricated during the course of the project; which leads to the recommendation to investigate the simplified technique and its use in 16mm film production.
