Rockland Blueprint Kit - As the product name states, Blueprints are blue images of photographs or drawings. Inasmuch as they produce a vivid, cyan blue, they are also named "Cyanotypes". Blueprints have been traditionally used to make copies of architectural drawings.
Blueprint paper is no longer manufactured for this purpose, but the method continues to be popular and is a feature of the New Photography. Painting Rockland's blueprint solution onto watercolor paper makes a homemade sensitized paper. A negative transparency or drawing on clear plastic is laid over it; sunlight exposes it and running water is all that's needed to make it permanent.
Note! Transparencies can be made (1) with a glass plate coated with liquid emulsion or a sheet of litho film or (2)digitally with a scanner and inkjet or laser printer or photo-copier
- An easy way to make photographic prints without a darkroom
