Kelham Pride Trichrome
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.
The small images at the bottom are, from left to right, the blue, green and red components.
