What is the most important thing to learn photography?

You have a good eye for finding beauty ~ ~ Here are three photography essentials given to you by the New York Institute of Photography ~ ~ 1. A good photo should have a distinct theme (sometimes called a theme). Or show a person, or show a thing, or even show a story of the theme. The theme must be clear and definite, so that any audience can see it at a glance. A good photo must attract people's attention to the subject, in other words, let the viewer's eyes turn to the subject immediately. 3. A good photo must have a simple picture, including only those contents that are conducive to attracting the subject's attention, and excluding or compressing those contents that may distract attention.
