Response to HP5 Plus developed with PMK pyro

Hopefully the Ilford man will answer your question but for now I can tell you I've used HP5 in both 35 mm and 120 for several years and get the same result. I fill my tank with the correct temperature water for a few minutes to get tank, reel & film all the same temperature before dumping in the developer and the water from the 120 always comes out dark. I understand it's a coating Ilford puts on it to stop the light from bouncing back during exposure. There are technical terms for all this but they don't come to mind right now. Harv.
