unc is right, the unbelievable capability of our body to get used to the enviroment conditions is present in the sight as well, it adjust automatically according to the colour patterns, lights and shades.
I've spent the last two days trying to convince my wife, she thinks the eyedropper and line tool can do a varying shade line now. I've cut some out and pasted it right on top of the other, she still doesn't believe it.
The letter "B" is the same color as the square "A" and the letter "A" is the same color as the square "B" and I don't have Photoshop, so, the squares are not the same color.
The same? BS. Just look at them, they are clearly differnt. Are you going to believe some schmaltzy art program or your own, been with you since birth, eyes? jeez
