The mechanical eye: When photography reshaped the way painters see

That day marked the birth of far more than a technique—it was a new way of seeing the world. Photography, that "mirror with a memory" as Oliver Wendell Holmes would later call it, would force painters to rethink their art from the ground up. More than a mere tool, it became a mirror held up to painting, exposing its strengths and weaknesses, its conventions and its possibilities. For nearly a century, artists and photographers would observe, challenge, and inspire one another in a complex dance where each technical advance by one pushed the other to reinvent itself.

01The shock of perspectives: when the photographic frame defied academic rules

Imagine the Salon of 1865. Visitors file past the monumental canvases of academic masters, those carefully balanced compositions where every element finds its place according to immutable rules. Then suddenly, their gaze falls upon a painting by Manet: Olympia. A nude woman, lying on a bed, stares directly at the viewer with a gaze that is almost provocative. Her body is not idealized like those of classical Venuses; her pose is not graceful but almost vulgar. Worse still, the composition seems unbalanced, as if the painter had cut his canvas too soon, leaving awkward empty spaces.

What the critics of the time failed to understand was that Manet had deliberately adopted the visual language of photography. The tight framing, figures cut off by the edges of the frame, the harsh light that does not flatter the model—all evoke those photographic portraits beginning to circulate in Parisian studios. The painter even used a single, violent light source, like the magnesium flash of early photographers, to create those striking contrasts between Olympia’s pale skin and the dark background.

Degas took the experiment even further. In The Orchestra of the Opera (1870), he adopted a plunging viewpoint reminiscent of the first photographs taken from balconies. The musicians are not depicted in their entirety—some are cropped by the frame, others partially hidden by their instruments. This fragmentation of the subject, unthinkable in academic painting, became Degas’s signature. He even included "useless" details, like the sheet music occupying the foreground, as if the painter had captured a stolen moment without taking the time to compose his image.

02Light revealed: how photography taught painters to see differently

Before Daguerre’s invention, painters had mastered the art of light for centuries. But photography suddenly revealed aspects of light they had never truly observed. Take Eadweard Muybridge’s motion studies. When Degas discovered in 1878 the photographic sequences showing a galloping horse or a man descending a staircase, he was fascinated by these images that broke movement down into a series of successive instants.

This revelation transformed his way of depicting dancers. In The Dance Class (1874), he now captured poses that seemed suspended in time, as if light had frozen a precise moment of movement. The ballerinas’ legs were no longer drawn according to academic canons but as they actually appeared in space—sometimes blurred, sometimes distorted by speed. Degas even used pastels to create effects of blur that imitated the motion blur of early photographs.

Photography also revealed to painters the expressive power of shadows. Félix Vallotton, in The Lie (1897), exploited this legacy with a mastery bordering on genius. The scene depicts an embracing couple, but it is the cast shadows that tell the real story. The woman’s shadow stretches disproportionately across the wall, betraying an invisible presence—perhaps that of a hidden lover. Vallotton employed a distinctly photographic technique here: the shadow as a revealer of what should not be seen.

Even painters’ palettes changed under photography’s influence. The Impressionists adopted brighter colors to compete with the luminosity of autochromes, while Symbolists like Odilon Redon explored the expressive possibilities of extreme contrasts, as in those photographic negatives where whites become blacks and vice versa.

03The decisive moment: when painting learned to capture the fleeting

Henri Cartier-Bresson would later speak of "the decisive moment"—that unique instant when all elements of a scene align to create a perfect image. Nineteenth-century painters discovered this notion through photography. Before Daguerre’s invention, painting primarily depicted composed, posed, idealized scenes. Photography, on the other hand, captured the instantaneous, the spontaneous, the impermanent.

Manet excelled in this new art. In The Railway (1873), he depicted a scene that seemed stolen from reality. A woman seated on a bench, a book in hand, looks at something off-camera while a little girl watches with fascination the smoke of a passing train. The composition is unbalanced, almost clumsy—as if the painter had seized a moment without time to arrange it. Critics of the time saw it as negligence, but we now know it was a revolution: Manet had understood that beauty could arise from imperfection, that reality was better than the ideal.

Degas pushed this logic to its extreme. His café scenes, like L’Absinthe (1876), seem to come straight from a photograph album. The figures do not pose—they are caught in natural, almost banal attitudes. The woman in the foreground stares at her glass with an expression of weariness that recalls those photographic portraits where models, exhausted by long poses, let their true personalities show through. Degas even used unusual angles, as in Woman at Her Toilette (1886), where the viewer observes the scene from an elevated position, as if looking over the model’s shoulder.

This pursuit of the decisive moment would profoundly influence later generations. The Italian Futurists, with their dynamic representations of movement, owed much to Étienne-Jules Marey’s chronophotographs. Even Picasso, in Les Demoiselles d’Avignon (1907), seemed to decompose his figures like a series of superimposed photographic instants.

04The shattered mirror: when photography pushed painting toward abstraction

At the turn of the twentieth century, something strange happened. As photography became increasingly precise, capable of reproducing reality with unmatched fidelity, painters began to move away from faithful representation. As if freed from the need to copy the world, they could finally explore other dimensions of their art.

Picasso was undoubtedly the one who pushed this logic furthest. When he painted Les Demoiselles d’Avignon in 1907, he was no longer trying to represent bodies but to decompose them as a camera would. The women’s faces seemed to be seen from multiple angles at once, as if Picasso had superimposed several photographs taken at different moments. This fragmentation of the subject, directly inspired by Marey and Muybridge’s photographic experiments, marked the birth of Cubism.

But photography’s influence on painting was not limited to the deconstruction of forms. It also transformed how artists thought about space. In the 1910s, Italian Futurists like Giacomo Balla explored the dynamic possibilities of chronophotography. In Dynamism of a Dog on a Leash (1912), Balla depicted the dog’s legs and leash as a series of superimposed movements, creating an impression of speed reminiscent of Marey’s photographs.

Even the Surrealists, in their quest for the unconscious, used photographic techniques. Man Ray, with his rayographs, created images without a camera by placing objects directly on sensitized paper. These experiments influenced painters like Dalí, who incorporated blur and superimposition effects into his canvases, evoking double exposures in photography.

05The photographic studio: when painters became their own photographers

Behind the great canvases that marked art history often lie thousands of photographs. Degas, for example, was a passionate photographer. In the 1890s, he took hundreds of photographs of his models, primarily dancers and women at their toilette. These images, which he never showed during his lifetime, reveal an almost scientific approach to light and movement.

These photographs were not mere preparatory studies—they constituted a genuine artistic exploration. Degas experimented with angles, tight framings, and plays of light and shadow. In a series of photographs taken in 1895, he captured a dancer getting dressed, using a mirror to create complex reflection effects. These images foreshadowed the bold compositions of his pastels from the 1890s, where mirrors played a central role.

Manet, too, used photography as a working tool. For Le Déjeuner sur l’herbe (1863), he drew inspiration from a Raphael engraving, but the final composition owed much to the outdoor group photographs beginning to circulate at the time. Even more surprising, X-ray analyses have revealed that Manet used a photograph as the basis for Olympia. Beneath the layers of paint lies the preparatory drawing of a nude woman, likely copied from an erotic photograph of the era.

Even artists who did not practice photography themselves collected images. Picasso owned hundreds of postcards and photographs that he used as sources of inspiration. In the 1910s, he even incorporated photographic elements into his collages, as in Still Life with Chair Caning (1912), where a piece of oilcloth imitating chair caning evoked photographic patterns.

06The invisible legacy: how photography changed the way we see

Today, as we are overwhelmed by photographic images, it is difficult to imagine how profoundly this invention disrupted artists’ vision. Yet its influence persists in every contemporary painting, in every installation that plays with perception.

Take Gerhard Richter, for example. In the 1960s, this German painter began creating canvases directly copied from photographs. His Photo Paintings meticulously reproduced blurry images, portraits, and landscapes. But Richter was not trying to imitate photography—he was exploring the boundaries between the two mediums. By painting a photographic image, he revealed something the camera could not capture: the artist’s subjectivity, the texture of paint, the materiality of the work.

Even artists who rejected figuration owed much to photography. Abstract painters like Mark Rothko or Barnett Newman were deeply influenced by how photographers played with light and space. Their monumental canvases, with their fields of color and depth effects, recall photographic experiments with filters and long exposures.

Even more surprising, photography changed how we look at old masterpieces. When we admire Manet’s Le Déjeuner sur l’herbe today, we see a modern, almost photographic composition. Yet at the time of its creation, this painting was considered a provocation, a complete break with academic rules. It was photography that taught us to see these innovations, that gave us the keys to understanding this revolution of the gaze.

07The endless dialogue: when painting and photography continue to respond to each other

More than a century after Daguerre’s invention, the dialogue between painting and photography has never been more alive. Contemporary artists continue to explore this complex relationship, sometimes merging the two mediums, sometimes opposing them.

David Hockney, for example, spent part of his career studying the links between the two arts. In the 1980s, he created a series of "joiners," photographic collages that imitated Cubist perspective. More recently, he used iPads to create digital drawings that further blurred the boundaries between painting and photography.

Other artists, like Gerhard Richter or Marlene Dumas, use photography as a starting point for their paintings. Their canvases, often blurred or distorted, question our relationship to images and memory. By painting from photographs, they reveal something the camera cannot capture: emotion, interpretation, subjectivity.

Even in the realm of pure photography, the influence of painting remains palpable. Contemporary photographers like Gregory Crewdson or Jeff Wall create images that resemble living paintings, with elaborate staging and meticulous attention to composition and light.

This endless dialogue between painting and photography reminds us of a fundamental truth: the arts do not progress in isolation but by inspiring one another, challenging each other, constantly reinventing themselves. The small copper plate presented in 1839 at the Institut de France did not merely give birth to a new medium—it forever transformed how we see the world, how we represent it, how we understand it. And if today we look at the masterpieces of the past with different eyes, it is perhaps because we now see the world through the lens of photography.
