The working principle of the camera

The principle of the camera can be divided into many aspects. Principle of lens imaging, 2. Shutter principle, 3. Film photosensitive principle. What you want to ask is the principle of the film part There is no difference between lens imaging tradition and digital, so I won't say much.

The photosensitive material of traditional cameras is film, and the light is imaged on the film under the control of shutter and lens. The silver iodide on the film is decomposed by light, and the image is recorded by using the different degree of light intensity decomposition. Also divided into color black and white, positive and negative. There are two kinds of photosensitive elements in digital cameras: CCD and CMOS. The materials are different and the principle is the same. The imaging light falls on the photosensitive element with a large number of pixels, and then the connected computer chip transmits the image data to the memory card.

The more detailed principle is that you search or read books online.
