Jason,

Thank you for the advice.  Would be interested to know the Guide Number of
your studio flash heads - please state feet or metres.


So that's no presoak and a water stop bath?


My next mission is to find a list of processing times for the Jobo - I
guess that most info. with films gives figures for auto. processing but
with the Jobo there are also filling and emptying times to consider.  My
CPE2 Plus has no lift.


Ordered some HSI about a week ago but it is on back order from Kodak.  The
delivery date is around April 10th so have a little longer to wait before
using it.  Saturday was a great IR day here in Bristol so made the best of
it with a roll of Konica and have a couple of places to revisit about 40
miles away when the HSI arrives :-)


All the best,

              Clive   http://clive.bel-epa.com
