trichrome Weston Park
Taken with a Trilogy 3D1000 camera in week 34 of my 52 film cameras in 52 weeks project:
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 Trilogy camera is very simple, with fixed focus, aperture and shutter speed, it is only suitable for use in bright daylight, and with the filters reducing the effective aperture by at least 2 stops, I played safe by push developing the film to ISO 800.
The three lenses produce slightly different views (this was the whole point of the camera, which was made to produce 3D prints) so in scenes with close and distant subjects, there is a loss of registration between the colours between these areas, in this version I have aligned the building in the distance, leaving the foreground flowers with ghost images.
