mi judi,
i forgot to tell that it seams
that fresh emulsions of liquid ligth
(exposed and develloped while still fresh) thend to get darker in the
fixing bath (kodak pouder fix or any hardening fix) and even the non
exposed part of emulsion get dark in the fixing bath, i use this to make
some kind of a frame around the photo...
this is all
ciao Riccardo
