In reading the section on film developing agents in Anchell and Troop's new
book I came across the following paragraph in the author's discussion of
the film developing agent Pyrocatechin (Catechol).
One interesting attribute of pyrocatechin is that this toxic benzene
chemical is a constituent of human urine. How or why the human body
manufactures pyrocatechin is something we will leave to future generations
of scientists-or theologians. Perhaps the Creator foresaw a time when
developing agents would be in short supply but film would be plentiful?
Any good film developing formulas out there based on human urine?
