Lumen Print & Chemigram Gallery

Lumen prints are made by exposing expired photographic paper to UV light, with various ‘resists’ and substances placed on top. They are then processed in a variety of development and fixing baths before drying. I often make them with botanical specimens, as the chemical compounds in the plants often react with the photographic paper in interesting ways. Ground turmeric, WD40, soap suds and other chemicals are also used, as well as toners like selenium.

Cyanolumen prints are a variation of lumen print made with cyanotype sensitiser (wet and dry). The above applies to that too.

Chemigrams are a method of producing images by using darkroom and other chemicals, as well as resists, to make marks on photographic papers.
