The imaging principle of the camera is 300 words.
Principle of camera imaging: The lens of the camera is equivalent to a convex lens, and the light from the object passes through the lens of the camera and converges on the film to form an inverted and reduced real image.

Supplementary knowledge:

How does the camera image and get photos?

The light emitted by the object passes through the lens of the camera and converges on the film to form the image of the photographed object. The film is coated with a layer of photosensitive substance, which will change chemically after exposure. The image of an object is recorded on a film, developed and fixed into a negative, and then developed with the negative to obtain a photo.
