Anthrotypes???
I have a question in my mind as to whether Anthrotypes, if only the bleaching of pigments, are really a photographic process. Certainly there is a reaction caused by light to bleach the pigments. What is the photochemical reaction? And, can sun tanning, as with a person's skin at the beach or such, be considered a photographic process? Indeed an image can be burned into the skin.
