Martin, it is a mystery. One of my favorite photos is a portrait of my wife (she said she'd kill me for the insurance if I ever showed it, and it showed up on the cover of a catalog....), on 8x10 TMY processed in PMK. Makes a nice pt print, but scanning it was a nightmare - I hadn't thought of it as a crystal growth but that is sure what it looks like. With Rollo pyro and Bergger 200, there is what looks like digital camera noise when scanning. I also have no idea. --Ken ----- Original Message ----- From: "Martin Wesley" <mwesley250@...> To: <DigitalBlackandWhiteThePrint@yahoogroups.com> Sent: Thursday, May 22, 2003 11:06 PM Subject: Re: [Digital BW] help with developing problem > ----- Original Message ----- > From: "Stephen Kobrin" <skobrin@...> > To: <DigitalBlackandWhiteThePrint@yahoogroups.com> > Sent: Thursday, May 22, 2003 3:02 PM > Subject: [Digital BW] help with developing problem > > > > I developed two rolls of FP4+ last night in HD-11 and do not recall > > doing anything I had not done 50 or 100 times before.
