Che Guevara Revolutionary Press Poster 1968
In 1968 I was playing around with ways of making colour fashion photos more exciting. Using 8x10 inch Ektachrome, I worked out a complicated process involving solarisation, high contrast black and white negatives and positives, coloured gels and a split-vision mirror, with which I could combine these with the original colour transparency to retain much of the original subject, but with heightened pure coloured areas added for a variety of effects. (Just the kind of effects which, just a few years later, were being done on a computer at the touch of a button.)
A smallish poster company saw some of these results, and asked if I couldn't use the process to produce an effective Che Guevara poster. They provided a small black and white of the famous photo of Che, credited to Revolutionary Press, which I manipulated to produce a very strong image. As they were only doing a relatively small silk-screen run, I provided separate films of the black, blue and yellow areas, which they printed on a red background (3x4 ft) for a four-colour effect.
