One of these optical illusions came across my desk again…
which claims that the fields marked A and B have the same gray level. Just looking at the image it is obvious that this could not possibly be. So, normally, the untrained non-scientific mind would push it aside, maybe say, wow, really?! and wander on.
But this is where I came in – a trained scientist! And this scientist now really had enough of this and went on the quest to look for himself.
I started up trusty photoshop, zoomed into an area that contained both the fields A and B, cut a bit out of field A and dragged it next to field B …
And what do you know? When the cut out little square from A is right next to field B, it is very clear that they are the same shade of gray – quod erat demimonstrum!
And we still trust our eyes? A little shadow so that the eye ‘thinks’ that the field must be brighter, makes it brighter for the eye. Could not help contemplating how many things there are that I don’t see and how many things I see that are not there.
UPDATE:
I was really surprised that there was so much discussion about this relatively irrelevant subject, but it went even further than somebody even accusing me of cheating. Somebody made a life-action demonstration this this little optical illusion and I just have to share this here:

are you sure that it wasnt saying the LETTER a and the LETTER b are the same shade of gray
hhahahahaha i think thats exactly right ashley – HHAHAHAHAH shut down in one sentence author..feel gooooooooooooooood?
That is cool! I did the same thing… and what do you know? It was right!
that ia really crazy! i couldn’t believe it!!!
Sorry folks but look closely . . . .
The little, lower right corner that came from the square A cut out is lighter. Also why is the square next to B not the same as the piece from A?
Call me . . . I have a bridge you might be interested in.
wow – I had not expected any comments on THAT post – this is so irrelevant – and yes, I really just cut out a square in photoshop and moved it – did not try to trick anybody – if you think of conspiracy then just try it yourself – it’s easy enough – and yes, this little (seemingly) white corner is really the medium gray from two fields above – but again – if it’s that important for you – just try it yourself. Then do something important and think about something like supporting our troops
i tried it and its true. I was sosurprised
Wow!
When i do that it doesnt come out the same
oh i did it wrong, it is the same shade..
omg dat is rlle weird lol it cant be right
🙂
wtf? this is retarted
of course the square next to B is the same w/ A, but because of the shade the color changes(RGB).
just tried it in photoshop using the eyedropper tool on the a b squares and other squares as well…a and b match…i need to review this further
Haha yeah for all you people that say it doesn’t work… try it yourself!
no this is true i got it on paint took out a square out of all the light spaces tht wer grey and put it onto the white space with the shadow onto it it works
its all about the shadow of the green cylinder.
aswq, I agree with you 100%
