[LargeFormat] Pyro Tips Wanted

[Lee Carmichael]

Hi Rich,
    I think the dark fingernails might not be caused by pyro.  Certainly not
PMK.  Most likely they were caused by Amidol.  PMK is a fairly new formula
by Gordon Hutchings.  Ed Weston had his own version of PYRO  it is called
ABC PYRO.  You can find the formula on Michael A. Smith's fine web page.

Also, in the book The Darkroom Cookbook by Steve Anchell page 128 and page
129.
