On Photography is a 1977 collection of essays by Susan Sontag. It originally appeared as a series of essays in the New York Review of Books between 1973 and 1977.

ContentsIn the book, Sontag expresses her views on the history and present-day role of photography in capitalist societies as of the 1970s. Sontag discusses many examples of modern photography. Among these, she contrasts Diane Arbus's work with that of Depression-era documentary photography commissioned by the Farm Security Administration.

She also explores the history of American photography in relation to the idealistic notions of America put forth by Walt Whitman and traces these ideas through to the increasingly cynical aesthetic notions of the 1970s, particularly in relation to Arbus and Andy Warhol.

Sontag argues that the proliferation of photographic images had begun to establish within people a "chronic voyeuristic relation"[1] to the world around them. Among the consequences of photography is that the meaning of all events is leveled and made equal. This idea did not originate with Sontag, who often synthesized European cultural thinkers with her particular eye toward the United States.

As she argues, perhaps originally with regard to photography, the medium fostered an attitude of anti-intervention. Sontag says that the individual who seeks to record cannot intervene, and that the person who intervenes cannot then faithfully record, for the two aims contradict each other. In this context, she discusses in some depth, the relationship of photography to politics.

Criticism and acclaimOn Photography won the National Book Critics Circle Award for 1977 and was selected among the top 20 books of 1977 by the editors of the New York Times Book Review.

In 1977, William H. Gass, writing in the New York Times, said the book "shall surely stand near the beginning of all our thoughts upon the subject" of photography. [1]

In a 1998 appraisal of the work, Michael Starenko, wrote in Afterimage magazine that "On Photography has become so deeply absorbed into this discourse that Sontag's claims about photography, as well as her mode of argument, have become part of the rhetorical 'tool kit' that photography theorists and critics carry around in their heads." [2]

Sontag's work is literary and polemical rather than academic. It includes no bibliography, and few notes. There is little sustained analysis of the work of any particular photographer and is not in any sense a research project as often written by Ph.D students. Many of the lesser reviews from the world of art photography that followed On Photography at the time of its publication were skeptical and often hostile, such as those of Colin L. Westerbeck and Michael Lesy.

In 2004, Sontag published a partial refutation of the opinions she espoused in On Photography in her collection of essays Regarding the Pain of Others. This book may be deemed as a postscript or addition to On Photography. Sontag's publishing history includes a similar sequence with regard to her work Illness as Metaphor from the 1970s and AIDS and Its Metaphors a decade later, which included a revision of many ideas contained in the earlier work.
