Digital cameras and film cameras don't work too differently, as both emit or reflect light from the subject through the lens to form an image on the focal plane.

Image Acquisition

Film cameras use silver salt (mainly silver bromide AgBr) sensitizing material attached to a plastic sheet (i.e., film) as a carrier, and the film has to be developed after shooting to get the photographs, and there is no way of knowing how good or bad the shooting was during the process, and you can't erase the photographs you took.

Storage media

Film camera images are chemically recorded on silver halide film. This item must not be exposed to light or it will be white or black when exposed and then developed.

Storage

Traditional camera images must be developed in a darkroom, to be processed digitally must be through a scanner, and the quality of the image obtained after scanning will inevitably be affected by the accuracy of the scanner.
