The image is a black and white illustration of a person's face in the center of a circular diagram. The diagram is divided into six sections, each representing a different aspect of the person's facial expression. 

The first section is titled "Basic Daylight Exposure" and has Chinese text written in both English and Chinese. The second section has a list of different types of lenses, including a DSLR camera, a Canon EOS 5D Mark IV, and a Nikon D7100. The third section has an image of a woman's face, which is the focal point of the diagram.

There are also several smaller images scattered throughout the diagram, including circles, squares, and rectangles. The circles are connected by lines, and the squares are labeled with numbers and letters. The rectangles are labeled as "ISO" and "ISO".

Overall, the diagram appears to be a visual representation of the basic daylight exposure of a camera.
