Not at all, if I can be of help. My speciality was far from photographic chemistry however. 





Welcome.

Excellent.

Do you mind if I occasionally run some questions by you relating to
chemistry?  (I lost my organic chemist brother this last year.)

Me I¹m very big on photographic chemistry. So feel free if you want my
opinion.

And from what I know of Mark on other lists, he really knows what he
is talking about when it comes to photographic chemistry.

Most of the chemistry going on here isn't the usual wet darkroom stuff.  It's getting far from there into something that smacks of 'real' chemistry.  Glad someone is looking after that part of it.  It's all I can do to find the 'on' button on the printer.

Between Darkroom chemistry and real chemistry there's a big gap it seems
I'm a darkroom chemistry guy.
"Organic" Chemistry to me means you buy your chemicals in the health food
store.
I had an assistant once who'd gone through a few years of college chemistry
and had to restrain himself when he saw me first in the darkroom.
I would say "put a NICE amount of stop bath into the tray"
(no that's Jewish cooking)
I believe there are "photographic" grades of many chemicals vs.
real life chemistry grades.
Vs. swimming pool grades.

A huge recent influence on me on the darkroom chemistry thing is Steven
Anchell who wrote "The Darkroom Cookbook" and with Bill Troop "The film
developing Cookbook".
These books changed my life as I know it.
I now have stock in Kitchenaid. (love the red ones)
Steven Anchell in the preferred of the first book admits he flunked
chemistry!

But wouldn't you guys be more into the chemistry of inks and pigments?
Of which I'm totally clueless.
Other than I'm on the side of the pigments.
