Visual anthropology is a subfield of cultural anthropology that is concerned, in part, with the study and production of ethnographic photography, film and, since the mid-1990s, new media. While the term is sometimes used interchangeably with ethnographic film, visual anthropology also encompasses the anthropological study of visual representation, including areas such as performance, museums, art, and the production and reception of mass media. Visual representations from all cultures, such as sandpaintings, tattoos, sculptures and reliefs, cave paintings, scrimshaw, jewelry, hieroglyphics, paintings and photographs are included in the focus of visual anthropology. Human vision, its physiology, the properties of various media, the relationship of form to function, the evolution of visual representations within a culture are all within the province of visual anthropology. Since anthropology is a holistic science, the ways in which visual representation are connected to the rest of culture and society are central topics.
