Re: Konica IR

Murray;
I'm afraid that to answer to your questions I would agree with Joe Paduano
in that I only know what's worked for me in the past under different
situations.(and hopefully I can acheive the same results later)
As for using iso 64 in the Pentax 6x7 with the fisheye lens' red filter,
perhaps it's a combination of the camera's meter, that particular red
filter, my processing technique (2 gallon deep tanks with dip and dunk
processing in straight D-76), my 12x12 cold light Alan Ross conversion on
my Beseler enlarger, and whatever other variables that might be involved.
As to the iso 8 equivalent:
   my math says 3 stops open from 64 is 8.
64 -1 = 32
64 -2 - 16
64 -3 = 8
As to hand held meters:
   for years I was using a Spectra Combi that could be set to measure both
reflected and ambient light and then average between them.  Now I use a
Minolta IVF meter usually in the ambient mode, but I do carry the reflected
disc attachment also.
And last, the backlighting question:
   it seems to me that when I look at a roll of film shot at various angles
to the sun, I would get the most pronounced IR effect when the foliage was
backlit. But perhaps time of day and/or time of year would have some effect
on this also.
Perhaps the best thing to do would be to just go out and shoot a lot of
film and select the images that look best to you and suit what it was
you're trying to say or depict with that image.
Now if I could just find a fresh source of Konica 120.  Is it already all
gone this year?
