Is the photo negative the original?

The photo negative is not the original picture. Negative film is a part of the original film, and the pixels are destroyed after rough modification in the photography shop, which is equivalent to waste film and cannot be reused. The original film is an unprocessed photo after shooting, which can be modified and adjusted at will.

Camera:

A camera is a kind of equipment that uses the principle of optical imaging to form an image and records the image with a negative. This is an optical instrument used for photography. In modern social life, there are many devices that can record images, all of which have the characteristics of cameras, such as medical imaging equipment and astronomical observation equipment. After the light reflected by the photographed scene is focused by the camera lens and the shutter for controlling exposure, the photographed scene forms a latent image on the photosensitive material in the camera box, and forms a permanent image after development and fixing. This technology is called photography, which is divided into general photography and professional photography.
