Centuries before photography froze the world into neat frames, scientists, poets, and artists streamed transient images into dark interior spaces with the help of a camera obscura. Julie Park explores the early modern fascination with this quasi-spiritual technology and the magic, melancholy, and dream-like experiences it produced…

The camera obscura, a device known as the photographic camera’s predecessor, was originally the size of a room. As an artist’s aid for rendering perspective, a scientific model for understanding optics, and a source of popular entertainment, it furnished observers with all kinds of information during the early modern period. In the context of pursuing knowledge about the natural world — whether in studying the sun, the light it emits, or the very organ for seeing, the eye — alchemists, astronomers, and mathematicians turned rooms in their homes into camera obscuras for revealing what was previously invisible.

In the most rudimentary terms, the camera obscura (whose Latin name means “dark chamber”) is a dark and enclosed environment with a hole on one side. This aperture allows light to stream into the interior space, casting moving images onto the opposite wall. Because its images of external reality appear reversed, both laterally and vertically — in colors deeper than their original, with movements intact but seemingly exaggerated — the camera obscura’s projections of the world re-envision it as a dream.

One of the very first mentions of the phenomenon behind the camera obscura is tied to the viewing of a solar eclipse. Aristotle, while observing a partial solar eclipse in the fourth century BCE, glimpsed its reflection in the play of light that seeped through the dense canopy of a tree. Here, the “dark chamber” is not a box or a room, but the critical space between solid things. Transposing this phenomenon onto the walls of domestic architecture, early modern natural philosophers made it possible to experience the domain of one’s personal space as a realm of marvelous reversal and illusion.

For Giambattista della Porta, polymath author of Natural Magic (1558), a book of natural philosophy and alchemy filled with magic tricks and scientific experiments, the camera obscura was a space for “see[ing] all things in the dark, that are outwardly done in the Sun, with the colours of them”. This evocative phrasing suggests the metaphysical happenings that the experience of being and peering inside a camera obscura offers. Della Porta’s instructions for engineering this “very pleasant and admirable” experience — among the “great secrets of Nature” — involve managing sources of light and creating the conditions by which it can be strategically channeled: “you must shut all the Chamber windows, and it will do well to shut up all holes besides”, except for one that is as wide and long as your hand. By covering the walls with paper or white cloth to create a viewing screen, the outside world will appear indoors, both familiar and estranged: “so shall you see all that is done without in the Sun, and those that walk in the streets, like to Antipodes, and what is right will be the left, and all things changed.”

A spiritual dimension inheres in this experience: the notion of illumination via obscuration that surrounds the early modern camera obscura carries remnants of the medieval period’s approach to darkness as the medium for perceiving the glorious light of God. Elina Gertsman explains how nowhere was this more evident than in windows through which light, both colored and clear, flooded into the darkness of cathedrals. Without the dimly lit cathedral space, this transmission of light as an expression of God’s splendor would not be so keenly felt. Both cathedrals and camera obscuras share the principle that dark places form the critical environment through which transformative light and its effects can be channeled. Yet in the case of camera obscuras, it was not just light alone, but ever more wondrous projections of the world that illuminated enclosed spaces…

[Park describes the camera obscuras of Johannes Kepler, Alexander Pope, Joshia Reynolds, and others…]

… While one might draw parallels with photographic technologies (both still and motion) — regarding how images are conjured by controlling an aperture — a key difference lies in the ephemerality of the viewing experience offered by the camera obscura. It captures life and its happenings as they take place, rather than preserving their images for the future. In other words, the moving images of the world it brings into its dark room are as transient as the dream state it appears to summon. And like dreams, the camera obscura could offer a new perspective on the world, to reveal things that might otherwise remain invisible. In 1764, the author of a dictionary entry on the camera obscura reflected on the ways in which the device underscores the motion of “the object itself”, such as a man walking, so that he appears to “have an undulating motion, or to rise up and down every step he takes”, in a way that could never be “observed in the man himself, as viewed by the naked eye”.

Despite their delight, the beguiled eighteenth-century viewers and inhabitants of the camera obscura’s worlds ineluctably expressed a sense of melancholy over the ephemerality of its projected scenes. Such sentiments are apparent in the numerous poems that appeared in the period conveying regret over the eventual disappearance of its pleasing phantoms. Yet, for a brief time, the camera obscura, especially when experienced as a room, gave individuals a sense of owning their own moving images of the world, in ways that might have felt far more vivid and evocative of one’s dream life than our own experiences with cinema are felt today. The moving images it mediates come from the viewer’s immediate environment, not from a world created by a scriptwriter and producer. This aspect of the camera obscura encouraged viewers to see reality in an unreal guise, both as an inner reality and a dream world, an elsewhere that is in fact quite nearby.

Paying attention to the historical role that the camera obscura played — allowing humans a safe and enclosed environment for accessing their imaginations, the sun, and many things in between — might transform the ways we look at our own spaces of solitude. Its visual effects can make us see that our emotional and mental landscapes are inseparable from the spaces in which we live and organize our lives. The very walls that provide us with shelter can also transform the world into scenes from a passing dream. By showing the world “with all things changed”, the camera obscura reveals just how clearly we can see in dark places…

As we marvel, we might send birthday greetings to a modern photgrapher who has resurrected the technique, Abelardo Morell; he was born on this date in 1948. While his work is wide-ranging, he is perhaps best known for turning rooms into camera obscuras and then capturing the marriage of interior and exterior in large format photographs, for example:
