I have used various photo papers in film holders, in pin hole cameras
and in my 4x5. I use an ISO of about 5 -10. One thing to remember is
that the range of paper is not the same as film, in that certain colors
register differently.(otherwise you couldn't use a safelight). This is
of course especially fun with a multigrade paper. Because different
colors seem to register different ways I use different ISO's for indoor
tungsten light (5) and outdoor solar light (10). Also , I have noticed
that the negative is a lot more contrasty when I use it indoors than
outdoors. I don't know why.
By the way, I have always enjoyed your comments from your days as a
photographer in New York.

DEAR LIST,
I recall in the distant past that there had been some discussion of
using silver gelatin enlarging paper in a view camera, eg, 4X5 sheet film
holders to produce a paper negative.
What I am hoping for is a starting point for an equivalent "ISO"
speed for the paper. Even a ball park would be great for me to start
testing. I know that it will vary with manufacturer and other variables but
it is nice to have some idea to save time.
I am not worried about image quality.I am just trying to get an idea
of some suggested ISO.
Thanks in advance.
CHEERS!
BOB
