From: thinman@netcom.com (Technically Sweet) Subject: What is reverse or negative video? Organization: International Foundation for Internal Freedom Lines: 23 I'm interested in simulating reverse (or negative) color video mathematically. What is the transform? Is it a simple reversal of the hue value in the HSV color space? Is it a manipulation in the YUV color space? How is it related to solarization? If you want to see something truly wild, turn on the reverse video effect on a camcorder so equipped, and point it at the monitor. This creates a chaotic dynamical system whose phase space is continuous along rotation, zoom, focus, etc. Very very surprising and lovely. I'd like to write a simulation of this effect without analog grunge. Thanks for any info you may have. Please e-mail any info to me. I'll post a summary.
