In 1990 the psychologist and artist Roger Shepard published a cartoon version of this effect, captioned “I stand corrected”, in his book Mindsights (page 91). I wanted to try a photo processed version of it and here’s my second attempt. When I tried before, back in 2008, I somehow couldn’t get my mind round what Shepard had done, and produced an even more twisted version.
My new version is based on a late nineteenth century Photochrom postcard. They were made by a beautiful process that added colour lithographically to black and white photos. You can see the original in a collection of gorgeous period cards of views from all over the world in the USA Library of Congress.
