PHOTOGRAPHIC PRINTING PROCESS
Cyanography; Draft:Cyanography; Cyanotypes
The cyanotype (from Ancient Greek κυάνεος - kuáneos, “dark blue” + τύπος - túpos, “mark, impression, type”) is a slow-reacting, economical photographic printing formulation sensitive to a limited near ultraviolet and blue light spectrum, the range 300 nm to 400 nm known as UVA radiation. It produces a cyan-blue print used for art as monochrome imagery applicable on a range of supports, and for reprography in the form of blueprints.
