Wimberley...W2D2 FORMULA

[Peter Schrager]

Need the,formula to mix w2d2 myself
Also dilution ..i think it's 20:20:400???
Also some developing times would be nice!!
THANKS in advance

 

[Gerald C Koch]

After very recently spending several days trying to discourage someone from using pyrogallol quess what? Ptrogallol is very toxic and really should not be used. Please read the thread '35mm and pyro something.'

To put it succinctly pyrogallol is classed as a level 4 toxin by the EU. It is absorbed through the skin and its effects are cumulative.

 

[Eric Rose]

Gerald appreciate your concern. However those of us who use pyro do so knowing the risks and as intelligent adults take the appropriate precautions.

 

[Gerald C Koch]

The thread is not just about the toxicity but also discusses the relative merit of staining developers versus conventional developers. All the claimed merits of pyro developers such as sharpness, fine grains, etc are available with other less dangerous developing agents.

It's all up to you but factor into any decision the possibility of a major spill of the developer or even worse the dry developing agent and take suitable precautions. Good luck.

 

[Peter Schrager]

Gerald I have been using pyro. for years..the only effect I can see I'm a little stained!!...
Michael thanks for the formula,
I usually use the pyro. MC but the formulary is getting pricey
I've had very nice results from W2D2 prior to ever using 2ND and it's simple to make up

Damn predictive writer on my cell phone
TOTALLY WHACK SO EXCUSE SOME OF MY SPELLING!!

Yes Peter I know this very well...
Cellphones are allways not writing what we are normaly spelling.
But let my say : Very interesting concern I see here with pyro formulations.
When I am home back again I just have a look to some formulations I have noticed far behind.
But it seams to me this one is a little different to the one I know.
Never mind about toxity.You just shouln't
drink this kind of developers.

with regards

If you don't like pyro start your own thread. For those of who use it and like it we neither need nor want your thread jacking.

Warning someone about the danger of pyrogallol is hardly thread jacking BTW it is also something that I will continue to do when I think it is necessary. Chill you'll live longer unless the pyrogallol gets you.

I am not opposed to one using pyrogallol. However it should be one an informed basis. Unfortunately there are some on APUG that see a new formula and feel the compulsion to try it. Often these are the people who do no other research. I also mention that catechol based staining developers are safer to use. The EU guidelines rate it as a level 3 toxin. While still toxic catechol is not considered a cumulative poison.

Those concerned with safety should google the term "darkroom disease." Studies indicate that those exposed to darkroom chemicals on a regular basis suffer from a statistically greater number of health issues than the general public.

You are right Gerald - the statistically greater number of health issues increases more and more within age,
the culminative type/danger of chemistry (toxity) and the time period
of contact/contermination.
And it reaches its height to the group
of people wich are proffessionals in labs : 8,5 hours/day - 5,5days/week -
49weeks/year - 12,8years before becomming darkroom deseases caused from contact during proffessional work.
Some kind of alergenic reaction can get much faster indeed ! (during days
after first contact - normaly after month typicaly to 85% within 8 years).
But I remember well my time at the army.Some stuff there was also not the best to some persons.
During military excercises we allway protect ourselfs with special equipment.AND when the danger in darkroom is at its top this kind of equipment would protect to 195% !
(much more protection as we all know from Robin Williams one hour photo [2002].... )
But I would say some cigars and a couple of gin / month is the much more danger in comparison.
But with pyro developer we should have some necsessariely protection but we would not need a full decontamination of the dakrroom after developing as I remember from the military excercises.

unless the pyrogallol gets you.[/QUOTE]

"Drinking 0,O7ml Pyro a day will NOT ceep the doctor away but it will increase
the time period so much that pyrogallol
could get you indeed"
But we all know 1) out of REACH 2) not something to drink 3) not something to have a bath with.

Yes of cause but one can

You believe in magic fairly dust. I have tried a large number of films and developers over the years (50+) and I know whereof I speak. Tetenal Ultrafin, Neofin Red & Blue, Ethol TEC, Rodinal, Ethol UFG, DK50, D-76, Acutol, FX-39, Royal-X Pan, Royal Pan, Tri-X, Neopan 400, 1600, 100, Kodak 2475 Recording Film, T-Max 100 & 400, High Speed Infrared, Ilford FP3/FP4 & HP4/HP5, Delta 100 & 400, Pan-F, Adox KB14, 17, 21, DuPont Superior cine films, DuPont missile tracking film, Brovira, Velour Black, Varilour, Varigam, 53-D, 55-D, Amidol, etc...etc...etc... You know what? There is no magic fairy dust!

Peatro Prime what the matter is gone with you suddenly ?

As we all know good methods/films/developer combinations and " bad " ones we should also know there are
ALLWAYS individual ways of preferences.
So where is the problem.

If somebody like it soo much to have
a swimming competition with crocodiles
he should do this indeed.
We should never advice such kind of person to do not so.
Because first : This is a free land
AND secondly : Everybody should have a chance to his own excperience.

with regards

PS : Ok - better ask such person in addition if he is an experienced one.
Better ask about insurance of live and about family?
Ok - better advice such person not to swimm in that case ...

Ähhmm sorry - but I like pyro- developer
and when we discus this affairs too much
it is no time left to use pyro.
And it is contraproductive!
