Mark,
You are absolutely correct as to only changing one variable at a time.
I am putting this Xtol thing up as I am finding a significant
improvement in my negatives shot in the same way, in the same places,
with the same lens.  Neopan 1600 is such a good film with my previous
practice that I have been surprised by the improvement with such a
simple change.  It makes the extra ten minutes or so shaking the film
worth while.

As to the twist, I got into the habit of twisting the can while
inverting because I didn't want to process the big tanks in the dark.
Proper technique was always to use the rod to lift the reels up, twist,
and dunk again.  By turning and inverting I could keep the lights on and
carry on a conversation.

As i see it the twist you gave it this time just clears off the surface
of the film real well -- a tad better than usual leaving a better
surface for fresh strong developer to be there and do it's job. The
difference to me would be very very slight unless you did it every
agataion cycle.

I look at wet negs but its a problem. Tell us how those bullet proof
dots look after they dry and see how they print. Maybe they're not so
bad.


Stuff can happen like you know you're going to do this new thing in the
dark so you alter your shooting; exposing approach. Then you blame the
darkroom thing.


Only one variable at a time (not that you're not doing this)

otherwise you got notin.

By the way doing continuous agatation like the Jobo you should try
thinner dilutions than 1:3 folks.

 Like 1:4 and be there. I bet it works. Works better. Work Work Work.
