Photography as a medium captured peoples realities since the early 19th century. With the years we used many imaging procedures, without really taking their harmfull chemicals in consideration. The newest and maybe last step we took in this regard, was moving to the sterile digital photography. Unlike with film, the light exites a digital sensor, which captures how many photons hit each cell on its array of cells. This information can then be digitally processed to resemble the object that was photographed.
