Trichromes
Three exposures. One frame. Red, green, and blue, shot through colour separation filters while the world moves freely in front of a stationary camera. The result is a full-colour photograph where moving subjects dissolve into ghost traces. Hidden in plain sight, until you look through the filters that captured them.
"Still camera. Moving world."

How trichromes work
Trichrome photography dates back to the earliest days of colour photography. A scene is photographed three times in sequence, once through a red filter, once through green, once through blue, and the three exposures are combined into a single full-colour image.
In the original technique, the subject was expected to hold perfectly still. My approach inverts this: the camera stays fixed while the street moves freely around it. Pedestrians, cyclists, and vehicles register differently in each channel, leaving colour-separated ghost traces in the composite.
Use the channel buttons above, or the R G B keys in the lightbox, to isolate each channel and reveal the subjects hidden within each exposure.
