Visual anthropology is a subfield of social anthropology that is concerned, in part, with the study and production of ethnographic photography, film and, since the mid-1990s, new media. More recently it has been used by historians of science and visual culture. Although sometimes wrongly conflated with ethnographic film, visual anthropology encompasses much more, including the anthropological study of all visual representations such as dance and other kinds of performance, museums and archiving, all visual arts, and the production and reception of mass media. Histories and analyses of representations from many cultures are part of visual anthropology: research topics include sandpaintings, tattoos, sculptures and reliefs, cave paintings, scrimshaw, jewelry, hieroglyphics, paintings and photographs. Also within the province of the subfield are studies of human vision, properties of media, the relationship of visual form and function, and applied, collaborative uses of visual representations. Multimodal anthropology describes the latest turn in the subfield, which considers how emerging technologies like immersive virtual reality, augmented reality, mobile apps, social networking, gaming along with film, photography and art is reshaping anthropological research, practice and teaching. Even before the emergence of anthropology as an academic discipline in the 1880s, ethnologists used photography as a tool of research. Anthropologists and non-anthropologists conducted much of this work in the spirit of salvage ethnography or attempts to record for posterity the ways-of-life of societies assumed doomed to extinction (see, for instance, the Native American photography of Edward Curtis) The history of anthropological filmmaking is intertwined with that of non-fiction and documentary filmmaking, although ethnofiction may be considered as a genuine subgenre of ethnographic film. Some of the first motion pictures of the ethnographic other were made with Lumière equipment (Promenades des Éléphants à Phnom Penh, 1901).
