Witho, I think I can answer your question with a definite yes, no and
maybe.
That is, many of us in the US use food gelatin (Knox), and in every test
I've applied (so far) it beat the photo gelatin, tho clearly that's only
my own working conditions. In fact the so-called "photo gelatin" didn't
clear at all in some cases. On the other hand, folks on this very list
have declared they find PHOTO GELATIN better. And, I'll add, my latest
tests with Photographer's Formulary photo gelatin were relatively OK, tho
in fact that gelatin was 10 years old -- I can't guarantee it's still the
same, and that was just one set of tests.
Is that perfectly clear? (Sorry.)
Judy
