The document describes how the chemistry of photography has evolved from classical silver halide techniques to digital technologies. It discusses how silver halides were used in early photography to develop images through wet chemistry processes on photosensitive paper. The transition to digital photography changed the paper structure, replacing silver halides and wet chemistry with inkjet paper and digital printing. The objectives are to describe this technological evolution and the impact on photographic equipment, the images themselves, and communication.
