Vidiot’s Luma Processor is located on the left hand side of the instrument. It’s purpose is to change the
properties of monochromatic (black and white only) video signals. Video from the external video input
is sent into it as the source image. The Luma Processor has a dedicated video output which can be
displayed, or the Colorizer can select its output as a modulation source directly.
“I first fell in love with solarization as a film effect in the late 60's while developing B&W photographic
prints. Even causing it was entertaining: you quickly turn white light on and off while the print is in the
developer tank. This causes a chemical reaction to occur which turns the lighter areas in the print to
negative, but what makes it look so dynamic is the outline between the positive and negative areas.
When I tried to create the same effect with video years later, I first tried full-wave rectifying the video
signal. I got solarization but soon realized that simply full-wave rectifying the video signal won't give
you that beautiful outline, so I set out to create circuitry that would. That circuitry is what's used in
Vidiot to give the solarization that special look. And Vidiot also lets you get inverted solarization,
something my original circuitry didn't.” - Dan Bucciano
