Since this lecture is mainly for introductory students, the content of the lecture mainly involves the structure of the camera: aperture, shutter, viewfinder, lens and eleven types of cameras. Through vivid pictures and detailed text introduction, the lecture gave students a clear understanding of the camera, the most important tool in the art of photography, and greatly facilitated the improvement of students' photography skills.

The students said: “We joined this association out of our interest in the art of photography. We didn’t know much about photography before. The lecture allowed us who are blind to photography to gradually enter the world of photography, which is very meaningful to us.”

According to Luo Li, vice president of the Photography Association, they will organize three such lectures this semester and will participate in a large-scale photo competition organized by universities in the capital in November. It is hoped that these activities can cultivate students' sentiments, enhance their aesthetic ability, and enrich their spare time life.
