[pure-silver] Re: PMK and MCS

I read and re-read and re-read Anchell and Troop, who I believe popularized the idea of avoiding acid fixation, to try and find out why they advocate against it. The only thing that I could find were suggestions tucked away here and there that modern films have higher iodine content than earlier films, and there is apparently something about this, having to do with how long things take, perhaps too long wash times, that lies behind the preference for alkaline processes straight through from start to finish. Perhaps I missed something. I know of no professional photochemist who sees it as an issue.

 Thank you Richard, Ryuji and Jim for the information.  I will try to
find the papers that Ryuji mentioned to satisfy my curiosity, but for
now, I think I will stay with the process that I am comfortable with.
As I read your comments, the advantages of all alkaline process seem to
be relatively minor.

John, I am somewhat relieved that the MCS is not photochemical-specific.
I have never experienced any reactions from the standard B&W chemicals
such a Dektol, acetic acid or Kodak Fixer, however I will probably start
using nitrile gloves dedicated to each tray for print processing and see
how it works.
