30-year old Neofin Red
Michael Scarpitti
boxes of unopened Neofin Red, both the original glass tubes and the
later plastic tubes. The developer in the plastic tubes had all turned
a very dark brown, so I threw them away. The two glass tubes looked
completely unchanged from new! I'm going to try them on something
expendable. Does anybody know where I can get developing times for
Neofin Red with current films?

Doesn´t matter - Willi Beutler (the guy who formulated Neofin) wrote
in his book "Meine Dunkelkammerpraxis" that Tetenal had problems to
seal the bottles and tubes at several time points. Whole batches were
ruined in the early 60s, so why not later, too?

But Neofin Red is out of production. Good luck with the two bottles -
the best would be to use it with the film they were intended for -
Efke KB100/R100. (Yes, I remember the Forte thread).
Two tubes should make about 8 films, if my brain doesn´t leave me in
the rain.

Because they're sealed and the color is still unchanged.

I think it's still made, and available in Europe.

Grrr.. I just wanted to inform you that "once before a time, Tetenal
had problems in the sealing process". They believed to have shipped
properly sealed tubes, but a number of people lost film by
underdevelopment.
I wouldn´t trust a 30+ year old glass tube without testing it (and
usually I don´t hesitate with experiments. After all, I use 5 year old
Rodinal. <g>).

You think it´s still made, but your wrong. Tetenal skipped production
and distribution... wait.. around 15/07/2002.
Tetenal doesn´t list it on theit website anymore, either. It was quite
an outcry, when they announced. Shortly after that, Ultrafin SF and
Negafin were cancelled, too. Plus them acessory items, like camera
enamel and others. People believed TT would leave the amateur
photograpical market totally.

Sure - dealers had the chance to stock it then. But most german
dealers aren´t able to deliver it, ´cause they ran out of stock.
To the group: is Neofin Blau/Blue still not available in the USA?

Yes, it's available.

Tetenal Neofin Blue Developer
Neofin Blue was created especially for Adox films by Schleussner Photowerke the
creators of the Adox formula. Today the Adox films are made by Fotokemika and
sold under the Efke name. This developer is a high acutance one shot formula
designed for slow speed films. 5 one shot vials. Each can process 2 rolls of
film.
IMO, one could just decrease the amount of sulfite in D-76H and get the
same results.

Fine. So, Efke-Users, go ahead with it. ;-)

Or use the published formula for the Beutler developer. That reminds
me.. I must have 4 tubes of´red left..

The red is/was different from the blue. The published formula probably
corresponds to the blue.
