How does the photographer highlight the theme?

In order to highlight the theme, the author must, on the basis of practice and observation, strive to get the essence from the rough, discard the false and keep the true, carefully screen what he shoots and remove unnecessary things as much as possible. After determining the subject, he should put other scenery in a subordinate position to make it play the role of setting off the subject. In order to highlight the theme, the author sometimes uses "title". An appropriate title can often make the finishing point. Generally speaking, the title should be highly summarized, with few words and sentences, so as to be subtle and intriguing and arouse people's rich imagination.
