yes...I'm well aware of the specs, but it is panchromatic and has promise with conventional exposure---can you maybe point me in the direction of somebody here in the USA who buys that stuff so I can ask them if they will sell me a bit of theirs to experiment with? Experiment is the word--paper isn't supposed to be exposed in a camera either, right?
the very first photographs were paper negatives !
it is just that glass and film became more popular ...
silver magnets, trickle tanks sold
artwork often times sold for charity
PM me for details
