That has been proposed at times but field reports indicate that it is
absolute nonsense. There are some people, for whatever reason, who feel the
need to complex-up a process. I guess it makes for good workshops.

I believe Dick Arentz has done some detailed study on this and dismissed
it. BTW, Dick is in the last moments of revising his book on platinum
printing and it is 30% larger. How's that for an accommodating publisher?
And A new section of digital negs written by one of our own here. Arentz
has done a bucket load of new research for the book and I expect it will be
quite exciting.
