as greenpro2009 has stated the video has not been altered.. i KNOW this only because i've made this illusion before and it does work.. what you may be seeing could be a result of your computer monitor trying to brighten/darken video, or even the camera used by greenpro may have adjusted some levels.. either way ive been watching a few of greenpros videos now, and i highly doubt this is a guy trying for 5 seconds of fame.. he's trying to educate you.

great question...it's been asked quite a few times within all of these comments too. it does work (you can see a very slight difference in lightness/darkness with the far left and far right rectangles...mostly because you already know that they are all different)...most people say they did just that and it works though...thanks for watching and commenting!
