Re: infrared pinhole

Thanks George

I was trying to compare it to the ususal film I use - CGP. I was hoping
the RRD film would be a faster film - but it appears to be even slower
than CGP. I had done tests with an enlarger that indicated RRD was much
slower than CGP. Was hoping in full spectrum (daylight) it may act
faster, but based on the test shot I did outside, it does appear to be
much slower than CGP.

Its a roll of film 30 inches wide - so I would like to be able to shoot
with it. I can't resist the idea of making 30" wide pinhole negatives :)
 Will play around with different developers, and maybe use zoneplates
with it.
