This is a reproduction print on archival paper using archival inks.
Each print is a reproduction of an original cyanotype created by Sarah Bourne Rafferty. The cyanotype 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. The process produces a beautiful blue color in reaction to the UVA and a delicate pale space in areas not treated with the light.
Each set comes with 8 blank cards and 8 envelopes.
Approximately 5" x 7".
Local Artist.
