I've started exploring a new-to-me old process called "gumoil" — it works on the principle that various chromates harden gums and other proteins when exposed to light.
There's a whole nexus of process based on this concept: Gum bromoil, gum bi/dichromate, carbon transfer, carbro... all of them related by this basic action. It is NOT based on silver.
In this case, the image is formed by the adhesion of printer's ink to the areas not exposed to light (and thus the gum is dissolved when the print is placed in water).

Just started working with it, using up some older paper.
