A shining screen.

I love this:

Since the 1970s, Sugimoto has worked on his photo-series entitled Theaters, in which he photographs auditoriums of American movie theaters, and drive-in movies, during showings. The exposure time used for the photograph corresponds with the projection time of the film. This allows him to save the duration of the entire film in a single shot. What remains visible of the film’s time-compressed, individual images is the bright screen of the movie theater, which illuminates the architecture of the space. That its content retreats into the background makes the actual film a piece of information, manifesting itself in the (movie theater) space. As a result, instead of as a content-related event, film presents itself here as the relationship between time and spatial perception.

"One night I had an idea while I was at the movies: to photograph the film itself. I tried to imagine photographing an entire feature film with my camera. I could already picture the projection screen making itself visible as a white rectangle. In my imagination, this would appear as a glowing, white rectangle; it would come forward from the projection surface and illuminate the entire theater. This idea struck me as being very interesting, mysterious, and even religious." Hiroshi Sugimoto.

According to Sugimoto,"Different movies give different brightnesses. If it's an optimistic story, I usually end up with a bright screen; if it's a sad story, it's a dark screen. Occult movie? Very dark."
