Image exposures on bromide paper, developed and fixed (in my cabin DeeWhy OB2 ~ 1952
While building OB2 during the day I was experimenting with photograms at night in my little cabin below the house.
The above photogram was produced simply by laying the same plant in two positions on a sheet of bromide paper at different times with different exposures to give contrasting images – then developing and fixing as usual in photography.
I was particularly interested in pendulum exposures using a flashlight as a pendulum with a pinhole source swinging above the bromide paper.
Man Ray played around with photograms at the Bauhaus in the early 1930s.
