Matt,
Xtol works best as a diluted developer, try the times given at the
massive development chart with dilutions of 1:2 or 1:3.  I have had
great results going down to 70ml of stock Xtol to 210ml of water(per
roll of 36) with all the Neopans, Tri-X, PanF, all the Agfa B&W's, and
Delta 400.  My times at 68F run from 13.5 minutes for Neopan 1600 to
17.5 minutes for Across.  As with all B&W try with something that
doesn't matter to dial in your system.

Xtol is very sensitive to oxygen so do not stir like a banshee when
mixing, do not use an aerator on your faucet for dilution, and do not
store the stock solution exposed to air.  Oh yes, follow the directions
as to temperature as some try to mix over 90F which causes failure.

Many on the list have given very good advice on storage.

One other problem that has come up is that if you have strange things in
your water then you will see lots of small clears spots on your
negatives.  For example, Brian, using water in the greater Silicon
Valley discovered that all the trace metals pumped into the ground
forced him to use distilled water.  Mark Rabinor, on the other hand has
water of the gods out of his faucet.

Over all, this developer properly used, is a tremendous advance over the
older solvent developers like D-76.  More sharpness, less grain, more
effective speed, and decent adjuvency effects.

I made up the 5 litres of Kodak XTOL film developer following the 
instructions.  Can anyone explain if I now need to dilute again. I am 
developing a single film in a Patterson container.  From what I can 
gather I need 100 ml for one film straight from the 5 litres, is this 
right ???

Matt
