Cyano Prints

Many many years ago when I was a curious child, I discovered some photo-sensitive paper in a basement cupboard.  I wasn't sure what it was, but I soon found out that when I placed objects on it and exposed it to light, the areas behind the objects stayed white, while the surrounding area turned a purplish brown.

Decades later, I ordered some specially treated fabric and tried the same experiment outside, using a plastic container lid and grasses for one, and Queen Anne's Lace flowers for the other.  I was really pleased with the results.
