Proportion
Proportion refers to the relative size and scale of the various elements in a design. The sole use of proportion in a photograph is to create visual interest, one element against another.
In this photo of a building, I see the building, and the somewhat dark sky. The proportion, can be seen in the building,and the fading night sky. This proportion conveys a sense of the underworld in my opinion. This image is appealing to me because the buildings color kind of matches the sky.
In this photo of a man walking on the beach, I see the man, mountains, and a beach. The proportion, can be seen in the man and the mountains. This proportion conveys a sense of freedom in my opinion. This image is appealing to me because it is a good photo.
