Classic Sensitizers Toners
All you need is sunlight.
As the name implies, Blueprints are a rich cyan blue, so are also named Cyanotypes. A transparency or drawing on clear plastic is laid over paper or cloth coated with blueprint solution, sunlight (or a halogen bulb)exposes it, and running water is all that's needed to make it permanent.
An all-in-one alternative sensitizer, FA-1 gives warm black images on paper and cloth. On paper, it can be used for a variety of classical processes including van Dykes (also called brownprints) and kallitypes (that resemble platinum prints.) On t-shirts, it gives a permanent image that does not stiffen the cloth. FA-1 is handled under room light, and requires a negative transparency. No darkroom or special equipment is needed-- only a halogen bulb for exposure. Makes one quart.
