- srean 16y agoOh awesome, this must have been it. I conditioned myself for about 3 minutes and it is working now. Let me see how long that lasts.
- jacobolus 16y agoMark Fairchild’s book Color Appearance Models has a nice couple of pages on high-level adaptation effects. Try the example on the page after this link for a demonstration of differing spatial frequency adaptation in each half of the visual field. http://books.google.com/books?id=8_TxzK2B-5MC&pg=PA155&lpg=PA155 http://books.google.com/books?id=8_TxzK2B-5MC&pg=PA155&#... There are some animated gifs floating around the web that you can stare at for a few minutes and then leave yourself with really weird perception of everything you see moving around depending on its color and orientation, sometimes lasting quite a long while. Vision is fun!
- sp332 16y agoThis property led to non-redundant effects being reported by people who had used computer monitors with uniformly colored phosphors to do word processing. These monitors were popular in the 1980s, and commonly showed text as green on black. People noticed later when reading text of the same spatial frequency, in a book say, that it looked pink. Also a horizontal grating of the same spatial frequency as the horizontal lines of the induction text (such as the horizontal stripes on the letters "IBM" on the envelope for early floppy disks) looked pink. I remember this happening to me! Anyone else?
