i shot some rolls of delta400 120 in south west national parks during
my last trip there with my wife. i couldn't shot slower film for a
number of reasons, i'm sorry.
i'd love to be able to make some very large prints, up to 20x24"
--well, for me it's *very* large: i've never gone any larger than
8x10"-- and i'm trying to understand what's the best developer i can
use for my films.
i suppose i'll have no contrast problems because landscapes were quite
contrasty and i used some coloured filters to have even higher
contrast.
i usually develop my deltas in rodinal 1+50 --as from digitaltruth--,
but have in stock also some d76, tmax and xtol. i wouldn't want to use
anything else because i'm not very good in preparing my own chemicals
at home and i'm not able to find easily other developers here in
italy.
the idea is to get the thinnest grain possible to be able to enlarge
that much without getting baseball-sized grain for such subjects :)
--i like thick grain for jazz concerts, but this is different--.
any suggestion is appreciated.
regards,

Hai capito, scelf?
I believe if you attempt to blow up delta 400 to 20x24" you are going
to see considerable grain no matter how you develop the film.
Xtol will give very fine grain and good sharpness, and should give you
adequate results for 20X24 prints. I've done 16X20 blowups of Delta 400
from a 120 neg, and gotten very fine-grained results. Rodinal will not
give you fine-grained results, and even D-76 1:1 will be grainer than
Xtol or one of the other Phenidone/Ascorbic acid developers.
thanks to everybody for your suggestions.

Xtol. Make sure it still works by developing a scrap
piece of film -- Xtol is known to go suddenly bad without
any warning or color change.
For the _finest_ grain use Microdol-X.

in grams, if possible.
i have tons of "prime" chemicals at home --i got them from the
professional that sold me his darkroom-- and may think about trying
your "brew".
I doubt seriously whether any other product will give you better
overall results.
tsp = teaspoon. That's a measure of volume, equal to 4.93 ml (or 4.93 cc).
The mass in grams varies with the substance, and perhaps with how finely
packed or well ground it is. Anchell's _The Darkroom Cookbook_ lists
sodium metaborate as being 4.6g per teaspoon, but he's got no figure for
ascorbic acid. I believe this is for US teaspoons; I'm not positive, but I
think that British teaspoons are a bit different.
FWIW, Kalajainen's developer is pretty similar to some of Patrick Gainer's
developers. Some of his earliest phenidone/vitamin C ("PC") developers are
described at http://unblinkingeye.com/Articles/VitC/vitc.html. PC-TEA and
PC-Glycol are also very simple but I don't know of a Web page devoted to
them. (They were described in the March/April 2004 issue of Photo
Techniques Magazine.)
PC-Glycol
---------
Stock A
-------
ascorbic acid 10g
phenidone 0.25g
propylene glycol to make 100ml
Stock B
-------
sodium carbonate, anhydrous 15g
water to make 1l
Propylene glycol is the main ingredient in "eco-friendly" car anti-freeze,
and you can use that if you like, but you might want to boil off some
water first, which will stink up your work area. You've got to heat it to
about 80C to dissolve the ascorbic acid and phenidone. You can experiment
with other stock B solutions if you like, and using sodium metaborate
would produce something very much like Kalajainen's developer. The two
stock solutions are mixed with water (about 1:1:50) at time of use. The
claim is that dissolving the phenidone in propylene glycol and keeping the
sodium carbonate in a separate solution results in very long storage life.
PC-TEA
------
ascorbic acid 9g
phenidone 0.25g
TEA to make 100ml
TEA is triethanolamine. In concentrated form, it serves as a preservative
(much like propylene glycol), but when mixed with water, it functions as
an activator (like sodium carbonate or sodium metaborate). TEA is quite
viscous, and in fact it freezes at about 20C. You must heat it to about
80C to dissolve the ascorbic acid and phenidone.
Personally, I've used PC-Glycol but not (yet) PC-TEA. PC-Glycol works well
for me, but sometimes the base+fog levels are a tad high. I've seen
suggestions that adding about 0.2g of potassium bromide may help on that
score, but I've not yet experimented with this.

This is just a convenient volumetric equivalent for grams. Since photo
developers are very forgiving creatures, very precise measurements are
not necessary. "Close enough for government work" is a common
expression used here for an approximation that works well.
So, keeping that motto in mind, 1 tsp. sodium metaborate = 5 grams.
1/2 tsp. ascorbic acid = 4 grams.
I make the 1% Phenidone solution by dissolving 1 gram Phenidone in 100
ml. 90% isopropyl alcohol. The stock solution will keep about a year at
normal room temperature. There are some who insist that propylene
glycol is preferable to alcohol, but I haven't had a problem with the
alcohol solution at all. 100ml is plenty to keep me going for about
4-6 months of shooting, and then it's a very simple matter to mix up
another batch.

I'm sure that in fact they do. Not for the sake of the Phenidone which
will oxidize eventually but rather for the ascorbate which oxidizes
very quickly as seen in the numerous failures of Xtol and other
ascorbate developers.
> It's sulfite that softens grain edges
>so that the film does not appear as sharp.
But of course the image is in fact sharper than those made with
low-sulfite developers as the grain defining the image edge is finer.
Also grain migration is less of an issue and most will agree that
higher sulfite developers such as D23 will deliver better highlight
detail than low-sulfite, high accutance developpers such as FX1.

I read John's comments as concerning the necessity of sulfite for
long-term storage of solutions, not the image quality of the negatives
developed with them.

Gainer has also experimented with non-aqueous solutions, using ethylene
glycol, propylene glycol, and triethanolamine (TEA) instead of water.
These seem to work pretty well for long-term storage, even without sodium
sulfite. I made some PC-Glycol four months ago and it's still good. I
posted the formula in an earlier message in this thread. If anybody's
interested but missed it, here's the Google Groups copy of it:
http://groups.google.com/group/rec.photo.darkroom/msg/d8cb974905671b19
However, since I rarely develop more than 2-4 rolls at a time, mixing a
liter of developer from scratch takes less than two minutes if I use a
1%stock solution of Phenidone dissolved in 90% alcohol instead of the
powdered Phenidone. Some say that the alcohol stock doesn't hold its
potency long, but I've kept it for more than six months without noticing
any difference in my negs. And the alcohol is cheap and much easier to
procure than glycol. I mix it in 1000 ml batches which is enough to
process about 25 rolls as a one-shot.
So measuring and mixing two liquid solutions (PC glycol and the
dissolved alkaline) is really no quicker for me than measuring a tsp. of
metaborate or carbonate, a half teaspoon of ascorbic acid, and a 4ml
medicine dropper of Phenidone stock. Just personal preference, not
better or worse.

I've been under the impression that bromide doesn't work well with
Phenidone derivatives. Has this been incorrect ?
Also, there is no way anyone can convince me that using a teaspoon is
as consistently accurate as using ANY scale. Spend $11 and buy one of
this digital jewelry scales on Ebay which is accurate to 0.1g.

I agree on the measuring but I think I'll stick with D-23. It might be
nice to have liquid concentrates of the more complex formulas
available but D-23 works for me.

I would still recommend mixing in at least a minimal amount of sulfite
to absorb the oxygen in the water and to help stabilize the forumla
during processing. I read somewhere (Meese ?) that any effects of
sulfite were undetectable until about 35g/L
>As for highlight detail, I get a very long tonal scale with very

And granularity and sharpness ? I'd be intersted in seeing a section
of the film scanned at high magnification.
You may be right about sulfite absorbing oxygen in the water; I'm not
enough of a bathroom chemist to know. But what advantage is that in a
developer that one is mixing fresh each time and using as a one-shot.?
Oxidation is not a factor .
I'd not heard that before, and as I wrote in my original post, I have no
personal experience with adding potassium bromide to PC-Glycol, so I can't
comment on this from my own experience. I was just passing on a tip I'd
heard.

A good case can be made for teaspoon (or other volumetric) measurements,
at least for some ingredients. Some chemicals absorb water from the air
and so change in mass over time. The volume of at least many of these
chemicals doesn't change as much as the mass when this happens. When
measuring these chemicals, therefore, a volumetric measure may be superior
to a measure of mass, particularly when they've been stored for a long
time and/or in containers that are permeable to air and the water it
contains.
Personally, though, I'm not a big advocate of volumetric measures for
photo chemistry, simply because most (but not all) formulas are presented
with measures of solid ingredients in terms of mass. That means you'd need
to refer to conversion tables, which might not even have all the entries
you'd need to do whatever formula you want to make. The conversion will
also require some rounding.
Gainer's recent formulas use glycols or other non-aqueous solvents rather
than water, so using sulfite as a way of absorbing oxygen in water is
unimportant -- at least, from the long-term storage perspective.
Kalajainen says he mixes his immediately before use, so again, long-term
storage isn't an issue.

You might want to order copies of the May/June 2002 and March/April 2004
issues of _Photo Techniques_ magazine. (You can do so at
http://www.phototechmag.com. Unfortunately, the articles aren't available
online, AFAIK.) These issues include articles by Pat Gainer relating some
of his experiments with vitamin C developers. The May/June 2002 issue, in
particular, includes a close-up comparison of identical exposures
developed in Rodinal, D-23, and something that's similar to Kalajainen's
developer that Gainer calls "PCK." The D-23 and PCK close-ups are
virtually indistinguishable in terms of acutance and grain size, at least
to my eye. The difference between both of these and Rodinal is quite
clear. The March/April 2004 issue includes full descriptions of PC-Glycol
(not under that name; the name seems to have been coined on the Internet),
PC-TEA, and a few others, including a description of a longevity "torture
test" in which a 4mm-deep pool of PC-Glycol "A" solution was left exposed
to open air for 16 days and retained full activity.

Generally I agree however my experiences with Xtol leave me very
suspisious of the stability of ascorbates. Unfortunately I'm old
enough to remember when we were told that OJ had to be consumed within
3 days from date of delivery or it woudn't have any Vit C left as it
all oxidized.

Since its in common use in the UK then I would not assume it is solely

Indeed, and for the Brits remeber 'the sun never sets on the British
Empire'. It would have been easier to invade Finland, then it would still
be true for part of the year for a lot less effort.
It is worth noting the French list. I wonder how different it would have
been if we had not been fighting with the French when we both had our
Empires at their heights?
Superpowers come, superpowers go...
And in reply to Peter's reminder of the sun never setting on the British
empire, I have a Canadian friend who used to say that the reason his
family (Tories in Boston during the Revolution) moved to Canada was so
they would have a better view of the sun setting on the British empire.
Ah, well, after having sampled the cuisine of both former empires, as
well as our own dear successor to them, I'd still have to vote for
France. As a dear friend of ours in Paris used to opine, "So many
restaurants, so little time, and so small a stomach." We did our best
to sample as many as we could and in ten years barely scratched the
surface of the foie gras.
But I did shoot and develop a lot of Delta 400 in my Gainer rip-off formula.

I once made a pot of chili seasoned with pounds of andouille. It had
to be the best damn chili I have ever made. Added a pint of Tennessee
sourgham, a cup of cayenne, onions, bell pappers, 3 different types of
beans and split a pint of Jack with the kettle just to make it legit
Tennessee chili. Believe me, nNobody on the top floor of my company
