Analysis on how to write photographic works

As the photography textbook of the New York Institute of Photography says:

"When discussing these photos, I only focused on three basic principles.

A good photo should have a distinct theme. Or show a person, or show an event, or even show a story link of the theme. The theme must be clear and definite, so that any audience can see it at a glance.

B\ A good photo must attract people's attention to the subject, in other words, make the viewer's eyes turn to the subject immediately.

C\ A good photo must have a simple picture, including only those contents that are beneficial to attract the subject's attention, and excluding or compressing those contents that may distract attention.
