Re: The State of Digital Cinema (none / 0)

Thanks Chris. I have seen variations on the top one, but not that exact one before.

The proof for the lower one, Adelson's checker illusion, is at this site: Checkershadow Illusion

Here is a number of illusions called: Lightness Demonstrations.

For a site of color-centric illusions: Illusion and color perception-Akiyoshi Kitaoka

This stuff is so fun, that I could spend a morning on it.

Motion, Form, and Mid-Level Vision: A Tutorial

There is also the illusion of using space when one presumes a flat object:
First
Second

If you see a proof of your top submission, please pass it on.

Never underestimate their intelligence, always underestimate their knowledge.

For some reason or other, I don't get the "proof". It convinces me that either the original image or the proof is an optical illusion, but I can't decide which. Using an image editor and moving a small piece from one square of the image to the other is what worked for me.
