Mirrored Gromit
Taken with a Trilogy 3D1000 camera.
Trichrome photography involves taking three exposures of the same subject on black and white film. Each exposure is taken through a red, green or blue filter. These photos are then combined to produce a colour image. Three separate exposures could be taken with the same camera mounted on a tripod, though this would only be possible for static subjects, a purpose made camera with three lenses allows the 3 exposures to be made simultaneously.
The process was first used by Sergey Prokudin-Gorsky over a hundred years ago, he used projectors with coloured filters to make a combined image, nowadays it can be done with photo editing software such as Photoshop.
For these trichromes, I used a three lens “Trilogy” camera, originally marketed for making lenticular stereo prints. I taped red, green and blue filters in front of the lens, and shot on Ilford Pan 400 black and white negative film.
