Guest Posted December 12, 2006 Share Posted December 12, 2006 there are loads of optical illusion type thingies out there, I know - many of them do the email rounds - but I haven't seen this one before... if you don't believe it - open it in photoshop (or equivalent - and check with the eyedropper tool - they ARE the same shade of grey!!)

Guest Posted December 12, 2006 Share Posted December 12, 2006 But they're not meant to be are they? And what effect does the shadow have then? There's no shadow on A, so the shadow apparently makes B lighter. Quote Link to comment Share on other sites More sharing options...
pianissimo Posted December 12, 2006 Share Posted December 12, 2006 Actually they ARE meant to be the same shade. In equal light, square B is lighter; but once it has the shadow on it, it becomes darker (and in this case becomes as dark as square A). The fact that it LOOKS lighter is just your brain compensating for the shadow while maintaining the relative shading in your mind. It's very clever.

feemcg Posted December 12, 2006 Share Posted December 12, 2006 If you cover up everything but the line A is on and stare at it for a while, A becomes lighter. Similarly B appears darker when you have less to compare it with......well, it does to me! Quote Link to comment Share on other sites More sharing options...

There's no shadow on A, so the shadow apparently makes B lighter. it's not a real chequerboard, Ginette - it's an optical illusion!

The Dogmother Posted December 12, 2006 Share Posted December 12, 2006 Graham took them off before he left the forum so we wouldn't still have them in the new year and no-one to take them off - he's thoughtful like that. Quote Link to comment Share on other sites More sharing options...
