Commentaires sur la formule

Agitate the negatives for 30 to 45" when they are first immersed in the hardener, or streakiness will result.
Leave them in the bath for at least 3 minutes between development and fixing.
If the temperature is below 29.5°C, rinse the negative for 1 to 2 seconds in water before immersing them in the hardener bath.
The hardening bath is a violet-blue color by tungsten light when freshly mixed, but it ultimately turns a yellow-green with use; it then ceases to harden and should be replaced with a fresh bath.
The hardening bath should never be overworked.
An unused bath will keep indefinitely, but the hardening power of a partially used bath decreases rapidly on standing for a few days.
This is a non-hardening stop bath for use up to 26.5°C.
Treat the films or plates in this bath for about 30 seconds with agitation at 18.5°C to 21°C between developing and fixing.
This bath should be replaced after approximately 13 rolls have been processed per liter.
