Beats having fingerprints and enchilada crumbs all over my negatives. The only solution that needs critical attention to temp is the developer. I use a digital clinical thermometer for that. A couple of minutes outside the bath will bring it to temp when it's a little over. - --Jorge. * * * * http://www.jorgemtrevino.com * * * * - ----- Original Message ----- From: "Alastair Firkin" <firkin@ncable.net.au> To: <leica-users@mejac.palo-alto.ca.us> Sent: Thursday, September 11, 2003 1:11 AM Subject: Re: [Leica] E6@home [was: Rant: another screw up by New Lab... > I would add, that the bigger Jobos are selling second hand at very > reasonable prices.
