Ripped off rock star
If you see a wild moiré pattern, it's your screen/monitor reacting to the tiny pinholes in the image...click to enlarge and the moiré should disappear.
Hi all -- tired ol' LW online virtually the same time Dave is, so fresh gloss on "moiré" for y'all.
(And.."hahaha!" to Dave. I don't think there are many words that'd scare you.)
Moiré is used to describe the interference pattern formed from overlapping pattern-on-pattern.
Etymology? Seems to have originated as a fabric term. From the warp-and-weft web to a pixelated Web, here's a tiny tour of "moiré."
I became familiar with this use of the term during my stint in graphic arts.
From http://www.dtp-aus.com/hlftone.htm --
"... The pattern created by 2 or 3 halftone screens layed at 30 degrees to each other is called a rose pattern, a seemingly simple and unobtrusive pattern that normally does not offend the eye. However as soon as we diverge from this ideal we start see a moiré pattern that progressively gets worse. ..."
And, since nothing exceeds like excess, here are some more moiré links:
I can't quite see through this one.
ReplyDeleteI just...keep...wanting...to pick...that tape...OFF!!! ;-)
ReplyDeleteThat's amazing! The tape and paper...they look like they are attached to my monitor and not part of the shot!! Crazy cool!
ReplyDeletePoor mb, I feel her pain!
