RE: KODAK HIE in 120 rolls

[Rolland Elliott <rolland_elliott@xxxxxxxxx>]

I recently talked to a Kodak representative regarding getting HIE in
120 format.  After a short discussion I found out that Kodak can make
70mm HIE that is unperforated.

The standard width of 120 roll film is about 61.5 mm. Therfore the
70mm  film could be trimmed down by removing about 8.5 mm from one
side, cutting the film in about 2.75 feet sections,  and then
attatching it to a 120 spool to be loaded in your camera.  The paper
backing could probably be ignored since it doesn't seal out the light
around the edges anyways.

I have made a simple device to cut down the film, however the biggest
problem lies with Kodak.  The minimum order for unperforated 70mm HIE
is 36 rolls (each roll comes on a spool that holds 150 feet of film). 
At over $200 (USA dollars) a roll,  the minimum order would cost me
over $8000 dollars.

I have also made a simple device that trims down Kodak's Perforated
70mm film by taking off 5mm from each side.  This leaves a 60mm wide
strip that is usable in a medium format camera, however, it is
difficult to process in the darkroom.  The standard Medium Format film
 developing reels are just a little too wide and the film has a
tendency to get out of alignment.  I trimmed down a plastic Jobo film
developing reel to process the 60mm wide film and it works fine.  

Of course this is a lot of work, but if you're an infrared fanatic,
then it's all worth it.  

So in conclusion, you can get HIE in Medium Format 120 roll sizes, but
it requres a lot of work that you have to do your self.

My next project is to try cutting down some color IR film to 220 rolls
for use in Medium Format equipment.  However, I probably won't get
around to it for a couple of months.  If you're interested in getting
color IR in 220 rolls email me privately. The film is expensive, so
I'll need to know if others are interested, before I invest my time
and energy into it.   I still have a few problems I have to work out,
but I think I will be able to do it.

Peace, Rolland Elliott
