    Ethical Perspectives 17 (1): 59-78. 2010.

According to William Mitchell, however, we are wrong to do so. Pictures made with digital cameras would not qualify as photographs, because they lack a certain realism essential to classical, i.e. film-based, photography. In the following, I first present two ways in which film-based photographs are realistic . Next, I discuss…Read more
