Could even be a problem caused by your rinse if you say it is abrasions. Clean all the way through the process and if your fixer is the least bit too old solids there may be the problem. _____ From: pure-silver-bounce@xxxxxxxxxxxxx [mailto:pure-silver-bounce@xxxxxxxxxxxxx] On Behalf Of Shannon Stoney Sent: Friday, February 20, 2009 5:03 PM To: pure-silver@xxxxxxxxxxxxx Subject: [pure-silver] Re: what causes pinholes in emulsion? I live in the tropics sometimes. It's tropical in summer here. I think I processed that film in the winter, though, when it wasn't all that hot in Houston. I always use developer at 70 degrees or so, but I don't always check the temperature of the stop. Maybe I should. --shannon On Feb 20, 2009, at 4:33 PM, BOB KISS wrote: DEAR SHANNON, I live in the tropics and always cool my film processing chems down to 68 ? 70 ° F when I use a stop bath. One of my students insisted that he could use D-76, stop and fix at room temp, 85 ° F, simply by reducing the dev time. He got the contrast right but had many pinholes. Is this a temperature issue for you? CHEERS! BOB
