Water bath pre-soak
Posted: Tue Oct 04, 2005 8:54 pm
I discovered that when using a water bath pre-soak in filtered water, I lose a bit of contrast, but get much more consistent development.
For T-grain film, I simply increased development time by 10% and that rectified the problem for me.

Indeed, pre-soak can induce a loss of contrast (experienced it with Xtoll).
I usually don't pre-soak but try to solve to homogeneity problem by pre-filling the tank before going in the darkroom.
This way, the developper is not poured 'violently' on the film but is gently and directly in contact with the whole film surface.

Oh, what type of development are you talking about?
In small tank, I don't think it matters (i usually add it in anyways).
On the other hand, water baths can be a really easy way to reduce contrast... no pulling required, which means less blocked highlights!
