‘On Photography’ by Susan Sontag | Summary and Exploration

by

In 1977, Susan Sontag published On Photography, a book that profoundly reshaped how we think about images. Far from a technical manual, this collection of six essays examines the philosophical, ethical, and cultural implications of photography. Sontag asks enduring questions: What does a photograph actually capture? How do we judge a “good” photograph? Can photography be considered art? More than answering these questions, On Photography probes our relationship with images and how they mediate our understanding of the world1.

This article offers a concise yet comprehensive overview of Sontag’s key arguments, while situating them in relation to other major voices in photo theory. It is designed for readers who want to grasp the book’s core ideas before diving into the text—or who simply need a reliable refresher.

The Genesis of a Masterpiece

Although published as a book in 1977, the essays that make up On Photography first appeared in The New York Review of Books between 1973 and 19772. Over those years, Sontag developed a sustained reflection on photography’s role in modern society, drawing on a wide range of photographers and photographic practices. Her analysis moves between the United States and Europe, engaging with figures such as Fox Talbot, Eugène Atget, Alfred Stieglitz, Edward Weston, Diane Arbus, Henri Cartier‑Bresson, and Nadar, among others3.

Like Walter Benjamin before her, who famously analyzed how mechanical reproduction transforms art and experience, Sontag is less interested in formal aesthetics than in the social and moral effects of the photographic medium4. And like Roland Barthes and John Berger, she treats photography not merely as a technique but as a cultural practice that shapes how we see, remember, and assign value5.

The Questions That Haunt Photography

Sontag’s inquiry centers on a set of persistent problems: What does photography do to reality, to the photographer, and to the viewer? By what criteria is a photograph judged “beautiful” or “good”? Can photography claim the status of art? And what does an image that so easily substitutes for reality reveal about us and our relation to time, memory, and power? On Photography does not offer final answers, but it sharpens these questions and shows how photographic practice is entangled with aesthetic and moral dilemmas6.

One of Sontag’s most cited claims is that “to photograph is to appropriate the thing photographed,” turning the world into a set of mental objects and establishing what she calls a “chronic voyeuristic relation” to reality7. In this sense, her work anticipates later debates about the ethics of looking, especially in documentary and war photography—debates she herself revisited and nuanced in her 2003 book Regarding the Pain of Others8.

Sontag’s reflections on photographic realism, on the beauty and ugliness of subjects, and on the way images transform our experience of time all contribute to a richer understanding of what photography is—and what it does to us. For Sontag, photography is not only a means of capturing reality; it is a tool for interpreting, organizing, and sometimes dominating the world9. Some critics, however, have argued that her account underplays the social and collaborative nature of photographic acts, or that her style—more meditative than systematic—makes her arguments hard to pin down in strictly sociological or philosophical terms10.

The Legacy of On Photography

On Photography has had a lasting influence on photographic theory, criticism, and visual culture more broadly. It helped establish photography as a serious object of philosophical and cultural analysis and continues to be widely read in university courses and by practitioners. The book’s skeptical tone—its concern with voyeurism, appropriation, and the moral limits of looking—remains strikingly relevant in an era of ubiquitous smartphone cameras and social media11.

At the same time, some scholars note that explicit citations of On Photography in contemporary theory have declined since the 1990s, even as its ideas circulate widely in more diffuse ways12. Ultimately, On Photography is as much about us as it is about images: about how we see, how we remember, and how we construct reality through photographs. It invites readers to question their own habits of looking and to recognize the power structures embedded in the image‑world we inhabit13.

Comprehensive Summary of On Photography, by Susan Sontag

  1. In Plato’s Cave: Sontag opens with a Platonic metaphor: photographs are like shadows on the wall of a cave—partial, decontextualized traces of reality. She argues that photography alters our notion of what is worth looking at and gives us the illusion of holding the world “as an anthology of images.” The essay also raises ethical questions: can we trust photographs as evidence, or are they instruments that can be used to shape perception and ideology?14 Her insistence that people “remember only the photographs” rather than the events themselves has been read as a precursor to later concerns about image‑saturated memory cultures15.
  2. America, Seen Through Photographs, Darkly: This chapter examines the development of photography in the United States, from early optimism (linked to figures like Walt Whitman) to a more disillusioned, realist, and sometimes surreal sensibility. Sontag traces how photographic practices both reveal and obscure social realities, using specific photographers to show how images construct competing versions of “America”16. In doing so, she anticipates later cultural‑studies approaches that treat photographs as active participants in constructing national narratives and identities17.
  3. Melancholy Objects: Here, Sontag focuses on the surrealist inflection of modern photography and the way ordinary objects can be made strange and significant through the lens. Photographs freeze moments and turn them into collectible, melancholic objects—reminders of time’s passage and of the gap between experience and its representation18. This emphasis on melancholy and fragmentation resonates with Benjamin’s reflections on ruins and modernity, though Sontag applies them specifically to the photographic image19.
  4. The Heroism of Vision: Sontag analyzes the idea of the photographer as a visionary hero whose “way of seeing” transforms the world into art. She explores how technical mastery and a distinctive style allow photographers to impose form on reality, while also questioning the romanticization of the photographic gaze20. Some critics read this as part of a broader modernist myth of the individual artist‑seer, a myth that later theorists of visual culture have sought to complicate by emphasizing institutions, audiences, and technologies21.
  5. Photographic Evangels: This essay distinguishes between photographers who present themselves as neutral documentarians of reality and those who claim the status of artists. Sontag discusses figures such as Berenice Abbott, Eugène Atget, and Robert Frank on one side, and Alfred Stieglitz, Edward Weston, and Ansel Adams on the other, showing how both camps justify their practice in moral and aesthetic terms22. Her analysis intersects with John Berger’s claim that the way we see is always shaped by power and convention; both insist that photographic “truth” is never innocent23.
  6. The Image‑World: In the final essay, Sontag describes a contemporary environment saturated with images—an “image‑world” in which photographs increasingly mediate our experience of reality. She considers how this proliferation affects memory, attention, and ethics, and briefly contrasts American and Chinese attitudes toward photography and representation24. This concept has proven especially fertile for later media theory, where scholars analyze digital platforms, social media, and algorithmic image flows as extensions of the image‑world Sontag diagnosed in the 1970s25.
  7. A Brief Anthology of Quotations (Homage to W.B.): The book closes with a collage of quotations about photography from writers, artists, and thinkers. Rather than offering a systematic conclusion, Sontag lets these voices resonate, underscoring the plurality of perspectives on the medium26. This open‑ended form aligns with her view that photography resists a single, definitive theory and instead invites multiple, sometimes contradictory, interpretations27.

Further Resources

If you’d like to go deeper, consider pairing On Photography with Roland Barthes’s Camera Lucida and John Szarkowski’s The Photographer’s Eye, two other foundational texts in photo theory. For a more explicitly political and class‑conscious perspective, John Berger’s Ways of Seeing is an excellent companion.
