Regina-born, Vancouver-educated Jessica Eaton patiently mines this subject. In her series Cubes for Albers and LeWitt (CFAAL), she explores these and other optical phenomena by repeatedly shooting grey cubes onto the same four-by-five-inch negative, using different gels and exposures. “I started working with the tricolour process in 2004 or so, having found it in an old Kodak photography manual,” she says. The results look rich, but why shoot these cubes? Why not make them digitally? Because the camera captures little imperfections—life, as it were—and proceeding from nature allows for unexpected discoveries.
