Analog and digital technologies clash with hypnotic (if not seizure-inducing) results.
I created this video by aiming a digital light projector (DLP) through an 8mm projector.
The DLP shined a blank white image through the shutter and the 8mm film. An HD video
camera aimed at the facing wall recorded the resulting image.
Single-chip DLP projectors alternate between colors and produce separate red, green,
and blue images at a rate of up to 20,400 rpm. Separation of the colors are sometimes
briefly apparent when the viewer moves their eyes quickly across the projected image.
This 'rainbow effect' is also visible when a fast-moving object passes between the
projector and the screen.
In this case the shutter of an 8mm projector, rotating at a rate of 48 flickers per second,
sustains the separation of colors. Overexposed sequences allow more of the DLP's
'white' light through the 8mm lens, resulting in a highly-pronounced rainbow effect.
Yet what the viewer actually sees ultimately depends on external factors. Some viewers
cannot perceive the rainbow effect, and some screens cannot display this video at the
correct rate. And no telling how this video will appear in the next generation of A/V
equipment. In short, media doesn't always survive transitions to the latest technology.
