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.
