i don't understand people talking about the danger of pyro
in photography there is so much products that are dangerous
and so much example of bad use of it
like photographer in the beginning of the century who use selenium as toner
and mix it without security
or the use of heavy metals (iridium,uranium,...)who create liver's cancer
and others
the illthness power of all products for alternative process and
traditionnal photo
if you don't take care that's a real problem, but in now days we know the
care we hace to take with every products.
chemist make studies on them so we know how to take care of each component
to all good prints, take care and long life
