[pure-silver] Re: Developer and Neg Density

Thank you, Richard.

These are the 2 pieces of info I was looking for. I have figured out a simple way to use regular gel filters in the Saunders, I can't believe this idea didn't occur to me before. Live & learn.

Another Sherlock Mystery solved!  Thank you!!

For 
_the same contrast_ extra-fine-grain developers, like Ilford
Perceptol, Kodak Microdol-X, Kodak D-25, all lose some film
speed, for these three its about -0.75 stop. Some developers
yield a slight increase in films speed, examples are Kodak
Xtol, T-Max, T-Max RS, and Ilford Microphen, DDX, ID-68, all
of which use some form of Phenidone. Not all Phenidone
developers yield more speed but these do, again about +0.75
stop. Again, this is for the same contrast.
      The color head settings for variable contrast paper will
not cover the full range of the paper. To get the end
values, i.e. minimum or maximum contrast, one must use
filters.    ---
