It is said that cameras can photograph things that people can't see. Is it true?/You don't say.
The human eye can only perceive a very narrow range of light in the spectrum, and the camera can capture more light that the human eye can't perceive according to the difference between the negative and the lens. For example, infrared photography can shoot objects in an opaque environment. Japan once produced a perspective camera, which used a special lens to shoot people, which could penetrate clothes and only shoot ketone bodies. X-ray photography can penetrate object photography to a certain extent and is commonly used in medicine. Of course, there are many special cameras that are not commonly used. Even the full-color film used by ordinary cameras can feel more light than human eyes.
