Jack Chambers (1931-1970) was a Canadian painter and filmaker who shifted from surrealist to photo-realist during his career. I was turned on to Chambers’ work via this article in Walrus Magazine about his unfinished masterpiece, Lunch (1971), which after working on for ten years, Chambers died before completing.
Chambers completed six films between 1960 and 1970, I tried to find footage online from one, The Hart of London, but they were taken down. I did find some excerpts from a movie about Chambers’ work and life here.
A couple other photo-realists working in a similar I’ve posted on previously are William Eggelston and Mike Bayne.
