I've processed some 35mm Delta 3200@6400 with Microphen stock solution (for 12 minutes - reference was Ilford chart) and the negatives came out incredibly thin.To be honest, temperature was 21 deg instead of 20. I'm about to start enlarging them but I can see from here that it will be pretty serious business. Any starter points I should have in mind before experimenting? Just so I could save some time, papers and nerves...
