Camera imaging characteristics

The imaging characteristics of this equipment are inverted image, restored image and real image.

There is a lens in front of the camera, which acts as a convex lens. The light from the object is converged on the film (equivalent to the light screen) through the camera lens, forming an inverted and reduced real image. The farther away an object looks, the smaller it looks and the closer it looks, the bigger it looks.

The camera uses the linear propagation characteristics of light and the law of refraction and reflection of light, takes photons as the carrier, and transmits the light information of the shooting scene to the photosensitive material in the form of energy through the photographic lens, and finally becomes a visible image.
