Often it's not easy to get clean negatives without spots, drying marks etc. Fernando e.g. asked what he can do to get rid of these spots. Instead of a reply as a comment here my thoughts about avoiding spots with all kinds of films:
Hi Fernando, the thin emulsions of microfilms show every fault unmercifully. No, I don't filter the mix, but I found that using destilled water for the developer is neccessary for microfilms no matter which developer you use. And the fixer can make problems. I sometimes had masses of white spots with most films and after trying a lot there was no other explanation left that the fixer had to be blamed. Now I use a more than 30 years old Agefix (no joke!) and have the cleanest negs ever. When the bottle is empty I will buy only premium branded fixer and nothing else. And again, use destilled water for the fixer! I had 2 different but cheap fixers causing many problems.
Rinsing I do with tap water, the final one again with destilled water that got a dash of dish soap. Put the film completely in this bath, then hang to dry and pour the bath with the dish soap over the film on both sides. No wiping.

happy new year
Happy new year 2014 everybody.
Medium format quality with slow technical (micro) 35mm films and Caffenol-C as a great and cheap developer compared to the dedicated and expensive soups? Yes, why not? The results are first class using a proven recipe and adjusted dev times. Using really fine resolving zoom lenses at bright sunshine make it possible to get great results even handheld, of course fast prime lenses are first choice for every subject.
There are also films from fresh production as Rollei ATO, Rollei Ortho 25, Rollei ATP, Agfa Copex Rapid, and of course the new Kentmere/RPX 25. The latter are not technical films and will probably need some more minutes dev time.
Another sample from the excellent Kodak Technical Pan, developed 12 minutes at 20 °C in Caffenol-C-L with 0.1 g/l pot. bromide, regular agitation, means first 60 seconds continuously, thereafter 3x every minute. Excellent tonal range even at heavy backlight.
Love and peace - Reinhold
