'Chemigram 8/2/61 I, 8 février 1961'

The simplest form of chemigram involves the application of photographic developer and fixer to gelatin-silver photographic paper, using the chemicals like watercolours. Developer creates dark areas, while fixer produces lighter tones. Cordier used this method here, pouring rather than brushing the chemicals on to a lightly oiled sheet of photographic paper.
