General update: Applied most of advices from you guys (couldn't get photoflow just yet). Got myself to develop a test film from my TLR (120 Tmax 400) and not much worth noting about it: * no traces but a little scratch probably made when getting the film into the spool. * no water / limestone traces or whatever.
It seems the washing part was indeed the culprit, or the major one. Since then I put the my brother's old enlarger to service. Old, basic, 35mm only but seems OK for now though the lens is probably sub par. 18x24 prints I made are OKish so I'm happy for now. 2010/12/25 Thibouille <[email protected]>: > Thank you John. > Indeed thé water is quite hard but I wouldn't have guessed that hard > water + dish washer would make things even worse. > > I'll fix the water and buy photoflo. > > Le vendredi 24 décembre 2010, John Sessoms <[email protected]> a écrit : >> From: Ann Sanfedele >> >> >> Thibouille wrote: >> >> >>>I didn't get this with my first film but second and third films have >>>traces on them after drying. >>>Seems like limestone (got the word translated from French so it maybe >>>wrong) and/or wetting agent. >>> >>>Now, I use simple dishwashing product as wetting agent.
