Photographic materials refer to the various substances used in the process of capturing images. This includes items like film, which is coated with light-sensitive chemicals, and photographic paper, used for printing images. These materials are essential for both traditional and digital photography, as they help record and reproduce visual information. In addition to film and paper, photographic materials also encompass chemicals used in developing photographs, such as developers, stop baths, and fixers. These substances play a crucial role in processing images, allowing photographers to transform captured light into visible photographs.
