[pure-silver] Re: D-Max with pyro

I take the advice in the instructions of WD2D+ - put your water pre-soak into the tank, then mix your developer, so you can add it to the tank the moment you drain off the pre-soak and it's absolutely fresh.




I think that success with the modern pyro and catechol developers
depends on being absolutely consistent in one's technique.  One example,
the amount of time between when the developer is diluted and when it is
used.

Pyrogallol was a popular developing agent in the 19th and early 20th
centuries.  I believe one of the reasons why it fell out of favor is
when films could no longer be developed by inspection.  There was a
problem of inconsistent staining. === The PMK formula stains very
consistently.  Certain films stain very well,
others don't, but from roll to roll, the stain looks very similar.  I
use an
all-alkaline process, though, and this helps.  Acid stop baths and
fixers
remove some of the stain, so having a longer fix time will result in
less
staining.

I don't use an after-fix staining bath.  I don't find it to be
necessary.
