I know - it's not really to do with Bryce, but I thought I'd post this to show how easily the human eye can be fooled by colours and shading. I thought it was pretty impressive - see what you think. Look at the squares labelled A & B. Obviously, square A is quite a bit darker than square B. About twice as dark, maybe, or three times? Actually, it isn't. Square A is EXACTLY the same shade as square B. If you don't believe me, save the image and check for yourself! (Original image by EH Adelson)

That's pretty cool. I made this image using bryce a while ago. WHat do you think?

Ummmm...no it's still two different shades...? Am I looking at this wrong?

Max, kinda like a mobeus or such, kewl. Tuttle, I saved the image and loaded in PS. Clicked on the two squares with the eyedropper. You're right, they are the same shade. This is a good reminder at the power of the mat lab and lighting around the textures.

Here is a site with quite a few illusions. Lots of these cam be used in the art we produce here, especially taking into account all the talent here.

AgentSmith, pull it into a image program and sample both squares. In Photopaint both squares are level 80 in greyscale.

I've see this type of illusion before but I still can't pull it off. It's neat to know though.

Ya know...as a Renderosity Mod I really should be p.c. at all times here... But Fu**ing Sh*t!!!!!!!!!! I took it into Photoshop....A and B are the same d*mn shade!!!!!!!!! This one is REALLY going to bake my noodle for some time to come. Thanks.

Honestly Tuttle I like you but I sure thought you were full of it! But after a closer exam in PSP I must ask that you never mess with my melon again. Vile

A simple method to determine if the squares are the same intensity . . . place a piece of white paper over a printed copy of the image . . .make a hole in the white paper at the location of each square with a pencil . . . and compare the squares. . . . yep, they're the same.

I'll never trust my sight again :)

There are some really awesome articles out there how vision works, the model of reflected/adsorbed frequency is just a childish simplification it turns out.

Amazing stuff... still have to rub my eyes. J.

So does this mean that when I see a pretty girl I should cut a hole in a piece of paper and look at her again through it?

Like that'll get her phone number.

Nice illusion tuttle, could not beleive it!
