Nick, just finished the Efke PL-25 negative. I developed for 9 minutes in Pyrocat-HD. 5 minute presoak, 30 seconds agitation, then 5 seconds of agitation every 30 seconds, water stop, 4 minute fix. Developed in a tray. The negative is a plus 1 negative that I will print in carbon. It is great to see an 11x14 ISO 25 negative! I did shoot it at box speed. I have found this to be the best with my developer and printing process.
