Perception

[Swede]

We all talk about quality, colorspaces and conversions and what we believe is the best.

Take a look at this illusion (http://www-bcs.mit.edu/people/adelson/checkershadow_illusion.html). The squares A and B *DO* have the same color but you probably wont believe it until you've checked this in photoshop (or even paint).

So, sometimes the eye deceives you and this don't make things easier for all testers. :)

That is just cool... & yes I had to load it into paint to prove it to myself :)

Cheers for that Swede,

ps
You can even make as small a version of it as you like with just blocks a & b in it & it still works beautifully...

Really strange...
What is the matrix? ;)


I checked it in a grahpics app and even deleted the A and B marks (which I thought would be responsible because they create a contrast) and copied a segment vice versa...

It's the same.
I'm deceived by my own eyes.

:cool: <-- I'm blind. :p
