Re: Re: Big Film Processing

[Robert Erickson <bob@xxxxxxxxxxxxx>]

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.
