As a photographer, what's your favorite theme?

What I like best is taking pictures of people. People's actions can attract the attention of the audience. In particular, the movements of hands can form geometric figures, such as right angles and obtuse angles, which combine with lines in other parts of the body to form irregular figures. These geometric figures are very attractive, which can firmly grasp the eye of the viewer in an instant, and then guide the details of various parts of the body through the action of the arm, which is full of endless visual sensory enjoyment!
