Silly me. I meant "Film developer for printing paper?".

Too much alcohol ah? Besides were you not in your own killfile,....
time to put your self back in. LOL.

No alcohol. I take particular offense at such aspersions, you lower-case
asshole.

Folks, "Just-another-a-hole" is Greg Blank who has this penchant for using
false names when he knows he's going to say something he should be fully
ashamed of.

Get a clue, Greg "Blank".

Greg Blank, you deserve a righteous virtual ass-kicking. Grow up.

At least according to conventional wisdom slow films have thin
emulsions and fast films have thick emulsions. I know from tests
done that a 120 roll of slow Pan F+ has much more silver content
than an equivalent area of print paper. I do not know a paper's
film equivalent ISO but the Pan F+ ISO is likely 6 to 10
times greater.

Mr. Knoppow has mentioned the extreme fine grain of paper emulsions.
In itself that supports the idea of papers having thin emulsions.
In fact IIRC, he has compared very slow micofilm emulsions to
print paper emulsions.

I suggest that paper is slow because it has a very thin emulsion and
little silver. I'd like to know more of the relationship because I'm
about to do some film developer tests using print paper. I think
the correspondence may be great thereby making for valid tests.

I'm hoping some others will shed more light. Dan

Nope. It has to do with crystal size and ripening, inter alia, not
'thickness'. Faster crystals are larger. See 'The Science of
Photography' fo more details.

Certainly he wouldn't buy it from you,......as you never say a thing to
be ashamed of. LOL.
