QTR-Quadtone RIP

Paul! Just remembered something re: a wetting agent!

I'm a pretty serious black and white darkroom photographer and for
years used PhotoFlo when washing film after development. But recently
I heard of something better, leaves fewer spots, and is much more
effective. It's called "LFN", which stands for Low Foam Non-Ionic.
It's made by Brandess and I got mine from B & H Photo of New York. I
seriously suggest you take a look at this product. I've come to much
prefer it over Photo-Flo, in fact I tossed my remaining stock of that.
If you go to www.photo.net and search on LFN you'll find more
information it.

I hope this helps The Cause!
