OPTICS BEFORE PHOTOGRAPHY

Optics Before Photography

Photography fixed an image for the first time in the early nineteenth century. Yet the observation that a small hole in a dark space projects the outside world upside down was written down more than two thousand years earlier. This page sets out, with sources, when and where that observation was recorded across fourteen stages, and how it led to the camera and to photography.

01 / PHOTOGRAPHY

Nicéphore Niépce and 200 years of photography

The French Ministry of Culture is marking the bicentennial of photography from September 2026 to September 2027. Because institutions date the surviving photograph to 1826–1827, this page treats the bicentennial as a two-year milestone rather than claiming that the invention falls on one exact anniversary in 2027.

What did Niépce invent?

Nicéphore Niépce was a pioneer of photography who developed heliography to preserve images made by light. He did not invent the camera obscura itself: the apparatus for viewing an image and the process for fixing it are distinct developments.

What is the earliest surviving camera photograph?

View from the Window at Le Gras, dated to 1827 by the Harry Ransom Center, which holds it. Here, ‘earliest’ means the earliest known surviving photograph made with a camera obscura, not every kind of image produced by light.

How does heliography record an image?

Light-sensitive bitumen on a pewter plate records the view projected by a camera obscura. Niépce called the process ‘sun writing’. Its significance lies in combining optics with materials and a process that preserve the image. This photograph cannot be identified as a pinhole photograph.

So when was that visible-only image first described? The optical passages of the later Mohists in the Mozi, from roughly the fourth to third century BCE, are read as describing light crossing at a small aperture so that a person's image is inverted. The phenomenon was recorded more than two thousand years before photography.

In most accounts of photographic history this long prelude is compressed into the single phrase 'camera obscura'. In fact it holds several distinct kinds of work: recording an observation, improving an apparatus, using the projection as a drawing aid, and finally inventing a way to fix it. A pinhole camera is a device that still uses the principle of the first of those stages.

This chronology does not attribute the pinhole camera to a single inventor. It places observation, apparatus, recording and expression side by side as separate efforts that accumulated in different regions and periods.

The method of forming an image with an aperture alone did not disappear once fixing became possible. In the later twentieth century it was chosen again, precisely as a way of stepping back from the resolution and focus that a lens takes for granted.

02 / HISTORY

A History of the Pinhole Camera

The history of the pinhole camera runs from observing an image projected through a small opening into a dark space, to fixing that image on a light-sensitive material, and on to contemporary practices concerned with light, time and space. It is not the story of one inventor, but of observation, apparatus, recording technologies and artistic expression developing in stages across different places.

The moving pictures within the timeline are imagined reconstructions of each period. The figures, buildings and tools are imagined; the behaviour of light follows the timeline and its sources.

  1. Around the fourth to third centuries BCE

    The optical passages in the later Mohist writings collected in the Mozi are interpreted as describing light crossing at a small opening and forming an upside-down image of a person. This is not an invention attributable to Mozi himself, but is interpreted as one of the early surviving accounts of pinhole image formation. [1][2]

  2. Imagined reconstruction
  3. Compiled from the third century BCE to the early seventh century CE

    Book XV of the Greek Problems asks why sunlight passing through quadrilateral openings forms circular images, and why eclipse light passing through a sieve, leaves or interlaced fingers produces crescents on the ground. It is not an authentic work by Aristotle and was compiled over many centuries, so it does not establish his personal observation or invention. [15]

    When I saw a photograph of the Teshima Art Museum, I noticed that the floor was tinged with blue. I understood this as a camera obscura phenomenon in which the sky was projected onto the floor. Using cardboard, I projected a landscape onto the ground to compare a large opening with a small one. To me, the landscape projected through the larger opening felt more beautiful. There is something interesting even in a landscape that does not appear clearly. This work grew out of that discovery.

  6. Early eleventh century

    Ibn al-Haytham (Alhazen), a scholar of the medieval Islamic world, described an image formed through a small opening in a darkened space. Pinhole projection also served to study eclipses and the rectilinear propagation of light. [1][15]

  7. Imagined reconstruction
  8. Around 1508–1509

    Leonardo da Vinci recorded how an exterior scene passing through a small opening into a darkened room appears reduced on paper, upside down, and with its colours and forms. The observation remained unpublished during his lifetime. [1][3]

  9. Observed in 1544 / published in 1545

    Gemma Frisius observed a solar eclipse at Leuven by projecting it into a darkened room, then illustrated the method in a book published the following year. The relationship between aperture, dark interior and projection could now circulate in print. [4]

    For an art event in Iya, Tokushima Prefecture, I turned an old thatched-roof house into a camera.

  12. Mid- to late sixteenth century

    Lenses and mirrors were added at the aperture to produce brighter, sharper projections, developing the pinhole dark room into an optical camera obscura. Its uses widened beyond astronomy to surveying, spectacle and other practices. [1][5][17]

  13. 1604

    In Ad Vitellionem Paralipomena, Johannes Kepler connected dark-room projection to theories of optics and vision. A Max Planck Institute history locates the term camera obscura—more strictly camera clausa—in this work. It was a milestone in naming and theorising a known principle, not the invention of the apparatus. [16][17]

  14. Seventeenth to eighteenth centuries

    The room-sized camera obscura developed into tents, sedan-chair forms, boxes and pocket models. Artists and draughtspeople copied its projections as drawing aids, while it also became an apparatus for entertainment and optical investigation. [1][5][17]

  15. Imagined reconstruction
  16. Around 1826–1827

    Nicéphore Niépce used a camera obscura and a bitumen-coated metal plate to preserve a projected image. The surviving heliograph cannot be identified as a pinhole photograph, but it marks an important transition from viewing a temporary projection to retaining a photograph. [5][6]

    Thinking that a room could also become a camera, I built my own 8×10-format camera and made this series with 8-hour exposures.

  19. 1856

    Scottish scientist David Brewster reported that he and the Reverend Mr Egerton exposed a photograph of a bust for about ten minutes through an aperture smaller than one-hundredth of an inch. He predicted that more sensitive materials could make a lensless camera with only a pinhole a preferred instrument. [7]

  20. 1890

    George Davison made An Old Farmstead, later known as The Onion Field, with a pinhole camera, printed it on rough paper and won a medal at the Photographic Society of Great Britain’s annual exhibition. Its soft image became a focus of debate between sharp and pictorial photography. [8]

  21. 1968–1984

    In the later twentieth century, pinhole practices again spread as ways of working with light, time and space. Eric Renner began making pinhole work in 1968, connected artists through exhibitions, workshops and publications, and established Pinhole Resource in 1984—one strand in a broader revival across many places. [9]

  22. 2001 to the present

    The official Worldwide Pinhole Photography Day site preserves records from 2001. On the last Sunday in April each year, pinhole photographs made around the world continue to be gathered into its online gallery. [13]

  23. 2006 to the present

    Since 2006, Meisai Okamoto has used pinhole cameras and camera obscura to make works concerned with light entering darkness, extended exposure, and the relationship between apparatus and space.

I wanted to capture 42 moments in time in a single landscape photograph. I made this work with the first pinhole camera I built, which measured 1.8 m.

In this work, a face is positioned inside a camera, and I project the outside landscape onto it. The landscape we see is also projected onto the face. I gave form to that idea.
