"Lines" ^
There are many lines with the stairs. The stairs all meet where the fireman is, drawing your eye to him.
"Balance" ^
The men on the two sides of the priest balance the photo because if it was just one man it would not seem to be equal. But the two men on each side put your eye to the priest while keeping focus on them also.
"Framing" ^
The blurred solider and flower around the child adds attention to her and makes her the main focus in the picture, along with her emotion.
Alfred Stieglitz
