Just before I left for the Fall Photo Weekend I processed a batch of Ilford Delta 100 4x5 in PMK developer. This batch was given N+1 Development to increase contrast. PMK is a developer formulated by Gordon Hutchings and it consists of Pyro, Metol and Kodalk [Sodium Metaborate]. It is a staining developer that yields a brown negative. The stain is proportionate to the amount of silver in the emulsion and it adds some density to the image. Negatives developed in Pyro hold extreme highlight detail. I quite like this particular developer and use it with both Delta 100 and Kodak Tri-X Pan. I have to remember to process it with my Jobo processor as every time that I tray process the negatives, as I did this time, I end up with some scratches in the emulsion. I finally found time to scan a few from this latest batch. Most of these date back to 2009, but a couple are from 2011 and 2012.
