moire' ring


Ok I give up. Like the rest of you I've seen enough dot com commercials to
last me till eternity, or the superbowl (whichever comes first). The form
usually involves comedy, and a host of screen shots of the offending website.

Now to my question. Why do all of these location screen shots have a moving
moire' pattern as well as a density "hole" usually surrounded by some type
of magenta ring. Any time a camera pushes in or out, changes focal length,
or even pans across a display shot, this pesky artifact makes the colorists
life a living hell. Unfortunately, most web pages have a white or light
background that makes this effect very noticeable.

Does anyone have an ID on this pain in my side, or any recommendations for
the shooters who feed me this syuff?
