... I developed a remaining (second) test film in diluted amidol SE20 paper developer. Not bad, although the negative showed the expected overall-amidol-yellow-stain, I could not find any disadvantage compared to the conventionally developed film. That makes me wonder if all our appreciated special-supersharp-high-definition-finegrain-pipapo developers are just a slightly potty fantasy. But because I am quite familiar with my carefully developed imagination, I would not like to believe my eyes and will act furthermore as if nothing has happened.
To cut a long story short forget it or try it I wash my hands of it!
