Occasionally a Photoshop contest appears, where dozen of authors submit their works in order to win a prize. One such contest was recently held, where the main theme involved optical illusions. I love it when I stumble across these, because it means bunch of fresh material for us! One of the submissions I found quite peculiar, was created by Nasir Khan and was based on a hidden girl’s face. Now, don’t be fooled like I was! The main hidden face isn’t the cloud one, nor the rock formation below what seems to be an impossible object of some sort. It’s something else instead. Closest hint I can give you is to look for the negative space. Something very similar to this one. Do you see it now?
