Response to Catechol-Metol

Thanks! You're right, I got no stains on the negs. The good things though is the very fine grain and better result with APX 100 than with D-76. I've always got strange mid-tones with D-76 and this film.

The Pyrocat HD developer seems interesting. I will try it when I buy Potassium carbonate later this fall.

Here is another Catechol/Brenzkatekin developer I will try, Mimosa No. 3:

A Sodium Sulphite 30 g Pyrocatechin 20 g Potassium Bromide 0,5 g

B Sodium Carbonate 120 g

For use, mix 1 part of I and 1 part of II with 10 parts of water.

I wonder though if the Bromide will affect the staining? Any thoughts?
