ARCLIGHT CINERAMA DOME
Hollywood, California

Close-up of one of the side panel machines. The early 3-strip cameras were no great shakes as far as registration goes, so today the projectionists are obliged to stay with their machines and ride the framing knob, making subtle adjustments with almost every scene change. At the heart of the machine is a devide called a "jiggle-o", which is a moving, comb-shaped affair near the gate which causes the side of the frame to blur slightly, helping to mask the join lines.
