Submission by wildholzkamera
Diazotype paper, used for copies of technical drawings is a very interesting material - is it useable as a photographic material? I built 2015 a very simple wooden box camera for Din A4 Diazo-Paper with a magnifying glass. Lens Diameter 130mm. Focal length about 300mm. Exposure times between three and five hours. Diazotype is a direct positive prozess.
