The blood was seriously dodgy! I tried with rosemary. I extracted the phenols by boiling the rosemary, then let it cool and filtered it, then added a touch of caustic soda and vitamin C. It worked really well for photo paper. Maybe I should try with film too.

Would love to see your results someday, Marco! I’ve read a lot about developing film in homemade chemicals but not printing. Very interesting.
