Tried caffenol printing on paper, took quite a while as the exposure times are much longer so loads of test strips. Ended up leaving this one in the tray of coffee for 15 mins and it turned out best. It's also really old bromide paper and took to the caffenol better than modern resin coated. The photo is an old boat at the plantings where we camped the first night on Hoy. It was right on the beach and we lit a fire - makes me want a simpler life as it was so relaxing.
Caffenol recipe 12 tspns coffee
