Thanks for this, I learned something. I'd be interested in what Mr. Harris thinks of the new Laser projectors, though. Has anyone, like Trumbull, seen them in action?Bob Furmanek said:One benefit 3-D movies had in the 1950's was brightness and resolution: you were seeing two 35mm prints interlocked with high powered carbon arc lamphouses supplying the illumination. When properly aligned and calibrated, brightness for dual-strip was not a problem.
The issue he describes as "blur and strobing" occurs when shutters are out of phase. Just the slight differential will produce an image that while not out of sync, still exhibits an un-natural look to movement. In the Fall of 1953, the Polaroid Corporation developed a set of controls which enabled theaters to correct any out of phase issue during projection. I installed one of these units in my screening room and it worked like a charm!
