Caffenol : like biscuits dipped into the coffee
he results did not leave me fully satisfied in terms of quality. Photos developed, probably improperly, were extremely dense, and only decent for scanning.
Also, surely, because they are C41 rolls (color, expired) processed in a black and white chemistry (homecrafted).
With a bew black and white film, like foma , used in the medium-format "squared" examples, the results have drastically improved.
But the stench remains, and causes domestic conflicts.
These experiments have anyway some charm, and it was definitely fun.
