Light Sensitive: Photography, Photorealism, and the Score
Bil Smith · Sound Morphology
A score is usually a promise about the future. It tells a performer what will happen, in what order, at what speed. A photograph is the opposite: a receipt from the past, proof that light once fell on something in a particular way. For several years I have been putting the two side by side, and lately inside each other. My scores now carry photographs the way older scores carried tempo markings: as instructions about how time should feel.
People sometimes ask why a composer needs a camera at all. My answer is that the camera is the most honest notational instrument I own. It cannot lie about light, only about context. And context is exactly what a performer has to build, every time, from nothing.
So the photographs in my scores are not illustrations. They are evidence, weather reports, and occasionally perjury. They sit next to the notation the way a witness sits next to a judge: not deciding the case, but changing how every word in the room is heard.

The lineage
I study photographers the way I study painters: for their operations, not their subjects. Each of these artists taught me something a score can do.
Thomas Demand: the model that disappears. Demand builds full-scale rooms out of paper and cardboard, photographs them with a large-format camera, and then destroys them. What survives is an image of something that was always a replica. I recognize my own scores in that loop. A tactile score is a built object; its photograph becomes the document that travels; the object itself may never be seen by an audience. Demand taught me that the photograph can be the work and the model can be the score, and that the gap between them is where the performer lives.
Olivo Barbieri: the city as a miniature. Barbieri photographs real cities from the air using selective focus, so that a band of sharpness runs through the frame while everything else falls into blur. Real streets suddenly look like architectural models. That trick of scale is a lesson in attention. In my scores, a passage can be "in focus" while everything around it softens: the performer learns to play a narrow band of clarity inside a wide field of suggestion.
Andreas Gursky: the composite that looks like truth. Gursky's vast images are often assembled from many exposures, seamlessly, until a stock exchange or a supermarket shelf becomes a pattern no single eye could see. He taught me that a believable surface can be constructed. My score plates are often composites too: many captures, many lights, one image that behaves like a single moment but contains several.
Thomas Struth: the viewer inside the picture. Struth's museum photographs show people looking at famous paintings, so the act of looking becomes the subject. A score is always watched by someone: the performer reading it, then the audience watching the performer read. Struth reminds me to design for that double gaze.
Cindy Sherman: the self as character. Sherman photographs herself in roles, costumes, and invented film stills, and in doing so shows identity as something staged. I ask performers to do something similar: to read the score as a script for a character who happens to share their hands. Some of my Performance Guidance texts are written for that character, not for the musician.
And others. Bernd and Hilla Becher, whose grids of water towers and blast furnaces turned repetition into structure. Hiroshi Sugimoto, whose long exposures of cinema screens compress an entire film into a rectangle of white light: a whole duration held in one frame, which is exactly what a sustained chord tries to do. Jeff Wall, whose staged scenes look like accidents but were built with a director's patience.
Three cameras, three kinds of truth
I work with three cameras. Each lies differently, and each lie is useful.
The Nikon Coolpix 8800: memory. This is an old camera, a prosumer compact from the mid-2000s with an 8-megapixel CCD sensor and a long stabilized zoom. By today's standards it is limited: noise rises quickly, highlights clip, detail is soft at the edges. I love it for exactly those reasons. Its color has the slightly sweet, slightly synthetic cast of early digital imaging, the color of photographs from a decade we now remember mainly through screens. When I photograph a score object with the Coolpix, the image already looks like a recollection.
In the score, Coolpix images mark the past tense. They appear where the music refers back to something: a quotation, a return, a passage the performer is asked to play "as remembered, not as written." Their softness gives permission. The performer does not have to be precise; they have to be faithful to an impression.
The Hasselblad X2D: testimony. At the other end is the Hasselblad, a 100-megapixel medium format camera, which I use with several lenses, including a macro lens for surfaces. It sees more than I do. Under hard light it records every scratch in copper, every fiber in a cotton ball, every thread of wire mesh. Under soft light it gives wood and wax a depth that feels almost tactile.
X2D plates are the evidentiary layer of the score: the definitive record of an object, a material, a surface. Where these images appear, the performer is asked for exactness. Clarity in the image becomes a demand for clarity in the sound. A fortissimo, in this system, is not only loud. It is fully resolved, every edge visible.
The Lomography Sprocket Rocket: rupture. The third camera is a plastic 35mm panoramic camera that exposes the film right across its sprocket holes, and lets me wind back and expose the same strip again. The results are wide, overlapping, and unpredictable: images bleed into one another, edges vignette, and the perforations of the film itself appear in the picture like a row of rests.
I use the Sprocket Rocket for passages about time itself. The sprocket holes are a ready-made rhythmic grid, a ruler printed by the film stock. Overlapping exposures become simultaneous events. When a Sprocket Rocket strip runs across a score page, the performer reads it left to right as a duration, with each perforation a possible pulse and each double exposure a moment where two times share one space.

Techniques, and what they ask of the performer
Around the three cameras sits a set of experimental methods. Each one changes how a page reads.
Selective focus. Borrowed from Barbieri's miniaturized cities. A band of sharpness crosses an image of a score object while the rest dissolves. The performer plays the sharp band as foreground and lets everything else become resonance.
Multiple exposure. With the Sprocket Rocket, two or three exposures share one frame. In the score, these mark layered time: a passage the performer may play over itself, or two tempos that must coexist.
Focus stacking and compositing. With the Hasselblad, I combine many exposures at different focus distances into one image sharp from front to back, the way Gursky builds images no single exposure could hold. These plates ask for total control: every voice audible, nothing allowed to blur.
Photographing the model. Following Demand, I build small physical scenes, sometimes from cardboard and paper, photograph them with the X2D, and keep only the image. The performer receives the photograph of an object they will never touch, and must play the distance between image and thing.
Staged self-portraits. Following Sherman, some scores include images in which a performer, or I, appear in character. These are not portraits. They are role cards, telling the player who they are while they play.
Degraded and transformed prints. Images printed and then heated, scratched, soaked, or exposed to sun, using photochromic and thermochromic inks on some plates. The image changes during the life of the score, so no two performances read quite the same page.

What this does to the score and the performance
The three cameras give me a scale of fidelity, and that scale becomes musical.
Image source | What it signals | What the performer does |
|---|---|---|
Hasselblad plate | Testimony, exactness | Play with full clarity and control |
Coolpix image | Memory, the past tense | Play as recalled, not as written |
Sprocket Rocket strip | Time, rupture, simultaneity | Read as duration and layered events |
In performance, the photographs can stay on the page or move into the room. Some are projected while the music is played, so the audience sees what the performer is reading. Others are deliberately withheld, so the audience hears the influence of an image it never sees. Either way, the images change the performer's relationship to the notation. A pitch printed beside a scorched copper plate is not the same pitch printed beside a soft, faded Coolpix photograph of the same object. The notes match; the testimony does not.
Closing
When I am asked which camera I prefer, I answer that I need all three, because each tells the truth about something different. The Hasselblad tells the truth about surfaces. The Coolpix tells the truth about memory. The Sprocket Rocket tells the truth about time, which is that it overlaps, slips, and never quite lines up with its own edges.
Demand builds a world and keeps only its image. Barbieri shrinks a city until we can hold it in our attention. Gursky assembles a moment no eye could witness. Struth turns looking into a subject. Sherman becomes someone else in order to show us how selves are made. A score can do all of these things, and the camera is how I learned that it could.
The work is written for a performer, yet it assumes several kinds of eyes: the lens that recorded the object, the reader who interprets the page, the audience that watches the reading. What you hear in performance is an instrument, of course. But you also hear copper under hard light, a memory rendered in early digital color, and a strip of film counting its own perforations like a metronome that refuses to keep still. That is the music I want to share.
