However, this happened to be one of the few things I already knew. I had tried very gentle agitation, which helped, but didn't eliminate the problem. It didn't seem logical to me that CONSTANT agitation would totally eliminate the problem, but it did. Old, but not too old to learn. BTW, I have been using Gordon Hutchings' pyro developer sold by Photographer's Formulary with what I consider to be wonderful results. Leica users that use black and white film and want to see what those wonderful lenses can do should consider pyro. It is extraordinarily sharp with a great tonal range. I've never tried pushing it, but it works wonders at normal EIs. Regards, Alan Brown
