This Photo I found on Big Spaceship. the black and white obviously create intense contrast. The thing about this design is that there isnt actually a white triangle, but the eye sees a white triangle. The three circles on the outside of the black triangle help lead us to believe that there is a complete triangle but there isnt. It seems like our mind kind of creates the triangle for us. Like we actually can see a hint of a shade difference that would suggest a line. The photos is symmetrical with there being pacman circles on each side of the triangle and... Each point of the non-existent triangle. That also makes the photo balanced. everything is equal in this photo.
