ela! i think it works like this. when u look at a complex picture with a lot of details from above, you might not notice some of those details. this concept is used to make the nature of the face to change when you step away. that angry look is basicly coming from the tiny changes in the skin of the face, and when you step back, you dont notice them.


why?i was trying to be smart! lol
