dangerous chemicals

guess) If you do the math he was 70-something when he passed on.

Weston used Amidol paper developer, which makes the finger nails black.

"To announce that there must be no criticism of the President,

is not only unpatriotic and servile, but is morally treasonable
to the American public."--Theodore Roosevelt, May 7, 1918

Weston used more pyro than Adams? It was my understanding that he used
Amidol.
Several years ago there was a lengthy thread on the photo forum of
CompuServe including
references about the toxic affects of the pyro-type chemicals (especially
when inhaled as a
powder, either when mixing, or after spilled liquids dried into a powder.
There were also
citations to the premature deaths of many factory workers who worked in
industries where those chemicals
were used for dying/tanning due to the workers soaking their arms in vats
full of the stuff. I no
longer have those files, as just about everyone at that time understood that
the stuff was dangerous. The
only debate concerned whether it was wise to use them anyway--that is, one's
confidence in his/her
ability to follow the necessary precautions. IMO it's dangerous to downplay
the risks to new darkroom
folk who may want to experiment with them, and might disregard safety
because posters on this
newsgroup find that humorous.

Right, you *do* need to use gloves--it's dangerous to soak your hands in
it
(such as
when tray developing sheet film).

Gads ! I wonder how Ansel ever survived the '30's ? !!

Amidol caused finger nail discoloration. Weston
died from Parkinson's disease.

*YAWN* Weston used Pyro developers for film, Amidol is what caused
the black finger nails. Weston used Amidol for printing, & one can use
Amidol as a two bath solution to process B&W film. JD is a respected
poster who has over the course if the years I have posted here acted very
responsibly. As for Adams his book the Negative goes into great detail
with regard to why the various developers like Pyro are not his choices.
Most people experimenting will hopefully do a little more research than
take someone's suggestion here and blindly run with it.

Are you afraid of Pyro? Then by all means don't use it. As for common
sense most people reading and posting here are well equipped to judge
the danger simply by looking at the skull and bones poison sticker on
Pyro packaging.

Afraid of Pyro? Hardly. I've used it for over 60 years.
I do, however, caution people--especially if they have
small children or pets in the home to use care with it. g
Peace.

As will glycin. Hydroquinone would probably do a fair job as
well but I was quite surprised to see how black glycin gets when
oxidized.Looks like tar.
