Spore Print Cyanotype Darkroom
Contact-printing mushroom spore prints using cyanotype chemistry on light-sensitive paper. Each print captures the radial gill pattern as a blue-white exposure record—the spores block UV light, creating ghosted negative impressions of microscopic reproductive structures. Combines mushroom cultivation knowledge with historical darkroom techniques and the patience of multi-hour exposures.

Spore Print Cyanotype DarkroomThe oyster mushroom's spore print has been in the sun for four hours. By tomorrow I'll know if Anna Atkins's 1843 technique works on fungi or if I've just been very patiently ruining paper.
