San Giorgio and tall ship trichrome
Taken with the Trilogy 3D1000 camera which I previously used 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.
One of the early users of the process, over a hundred years ago, was Sergey Prokudin-Gorsky , 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 HP5+ 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, particularly as the filters reduce the effective aperture by at least 2 stops.
