Hi, sorry for my little english... I'm italian I have a problem that I do not succeed to resolve. On some films (the greater part) I do not succeed to eliminate of the spots and most annoying black points. I thought initially next to the powder... but for my method standard I do not succeed myself to explain why of alternation of "perfect" films and "disastrous" films... you could help me? They are of the small spots and black points that I do not succeed to understand what are. I use demineralized water for all the process of development... comprised the washing. I use chemical new that I dilute only little before the development... I dry the film in a closed closet... If someone has interest I can send one small scansion of film. Thanks and bye.
