Re: 70 mm HIE in Hassie A70 Back

["Mr. E Crumpler, Jr" <nikonguy@xxxxxxxxxxxxxxxx>]

The only problem with this is that HIE won't last a long time even in the
freezer.
Same problem with 150 foot rolls of 70mm.  I've had both HIE and Konica age
out and
start producing significant fog.  I'd rather not get into the hassle of
handling sheet film for a single use
that has a limited life time of 1-2 years.  The sheet film camera is also a
collectable and I have it displayed on
my living room shelves, so the investment is not wasted.

I already have a adjustable tank that will handle up to 24 exposures of 6x6
film in about any width.
I have an absolutely light tight darkroom that was built as part of my new
house.  I also
soup all of my film in Diafine, so temp, time and agitiation are of little
concern .  Working in the
dark is no big deal.  I'll probably be ordering some of your 220 early next
year to try it out and see if
I can live with the grain in 11x14 prints from 6x6 and 6x7 negatives. That
will help me make up my mind about
Kodak in MF and if the move to 70mm will give me what I'm looking for. If
not, I may try the 4x5.
Or just move to digital and forget about silver IR photography.
