Shinagawa, Tokyo, January 2026

Digital trichrome triple-exposure, using a Steinheil 55mm f5.6 in a Prontor Press leaf shutter adapted to a Sony A7. Three photos with red, green and blue filters respectively, are exposed with the leaf shutter with the camera in bulb mode. The camera is controlled by a microcontroller operating the camera shutter via the remote interface. The microcontroller counts the exposures of the leaf shutter using its PC flash sync connection and ends the exposure after the leaf shutter fired a set number of times.
