BTW, while pre-soaks are often recommended there is no real reason
to use them except where there may be a wetting problem with the
developer. This is the case when Jobo machines are used and Jobo
recommends the soak. They are also recommended by Kdoak for tray
development of multiple sheets because a soak will eliminate the
tendency of sheets of film to stick to each other in the tray.
Soaking will affect the induction time and hence of total
development time so must be taken into account. The longer the
overall development time the less its effect. Induction time is the
time between application of the development and the time the image
first begins to appear.
I notice that the instructions with the Formulary's WD2D+ explicitly
tell you to do a pre-soak with water that has a small amount of
Photo-Flo -type chemistry in it. (They also tell you to mix the pyro
*immediately* before using it.)
Could the reason be to 'soften the blow' of an active developer as it
hits the film?
