My mate Tom Lehne is putting together a Caffenol film development workshop. If you’re around Hamburg, Germany, it’d be well worth looking into. He’s working with Larry of Lazarus fame, who, having 40+ years of professional printing experience, is inspiring to watch at work.
You can see the amazing results Tom is getting with instant coffee and a dash of special sauce on his website. This most definitely isn’t a case of “those who can’t, teach!”
[One of the alternatives i’ve been considering as my stock of Presto runs out is finding one of these old emulsions sold under brands like Fomapan or Efke and moving to Caffenol for development. It would be perfect if there was a decent, non-toxic replacement for fixer, but i’ve not seen much mention of that… perhaps it’s not that important, the fix is always going to contain the un-oxidised silver, and that’s never going to be good in the grey water. All that said, the Rodinal habit is hard to kick and i can see myself going Tri-X / Rodinal!]
