Nude swimmer is an hand made cyanotype print on Winsor&Newton smooth surface 150gr. paper. Cyanotype is an old photographic printing process invented in 1842. This is an hand pulled print done preparing paper with Ammonium Iron Citrate and Potassium Ferricyanide chemicals, then exposing paper with a contact negative (10x12 cm) to direct sunlight for 46 minutes. Every print is always different in tone and surface, so it's like a unique piece.
