The term photographic process refers to the entirety of all techniques in photography that are used to create a negative photographic image . In the negative process, the material changes inversely to the degree of brightness and the color of the light: dark becomes light, light becomes dark. In order to obtain an image that is true to the original for humans, the process must then be reversed again (negative-positive process).
