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.

I like how in this photo the shoreline directly behind the fish is highlighted  but the pavement to the left of it and the deeper water to the right of it is not. One can get a sense of texture from the dead fish and the wet highlighted pavement. The darkness of the mouth and the hole where the eye used to be suggests death, but the highlighted shoreline (which is also a vertical line) brings us right up to the blue sky which kindof suggests color and life. And this is a salmon so the circle of life of a salmon is really brought ot to me in this photo.
