Bob, You mentioned on the phone the other day about the Patterson tank.
What size, (or catalogue number) takn does it take forthe large film?  And,
what size grey pipe?

Steve Shapiro, Carmel, CA


For those who are interested in building their own tanks for processing, I
found that the gray colored pipe that is used in the electrical trades is
opaque. Years ago I would process 10 inch  by seven foot Cirkut film on
location. When I flew to a new town my first stop was to an electrical
supply house.

I would process with the tube on it's side. The film loaded with the
emulation to the inside. I used I gallon of each chemical and would roll the
tube from side to side on the floor for twice the recommended amount of
time. I would warm the tube with a "hot bath" of water that was about 5
degrees warmer that the processing temp. The prewetting also prevented
streaking that would show on the negative.

Now I travel with a Paterson tank. With it I can do any width film up to ten
inch by six feet long. Yes, Cirkut often comes seven feet long. I simply
keep my exposure to the first six feet of the roll.

The beauty of using the Paterson tank is that I can load it in a changing
bag, and process it in full light. I sometimes shoot group photos on
location on 10 inch by 6 foot film and run into the "men's room" to process
and print. The Paterson takes 1/2 gallon of each chemical in order to
process the 10 inch or smaller Cirkut film.

It is actually Genova's Rango brand gutter and down-spout system. I think
they are available in most of US.  There are other similar brands at home
stores. Genova makes a full range of pvc, cpvc pipe and fittings.
