I came across Mona Kuhn´s gallery and I´m really impressed by the
tonality. I´m really interested in knowing what kind of technique to
produce that kind of tone separation..., is it Pyro? Any ideas.

  Its almost impossible to tell from a web site. The images
will have been modified by the scanning process and at
several other stages including my monitor. To me they look
as though they are just excellent prints from good
negatives. Its not necessary to use any trick to get good
tonal rendition in a print but I've seen enough awful prints
to know that many find it difficult.
  Pyro developer has no magic. Supposedly, when used with
variable contrast paper the stain image tends to reduce the
contast of the highlights. This may be desirable for some
images but will result in flat looking prints for others. On
graded paper the stain simply reinforces the silver image
since it is opaque to the blue light to which these papers
are mainly sensitive. Exactly the same tone rendition can be
gotten with other, non staining, developers.
   I've seen Kuhn's work before, I think I've even seen
actual prints in local galleries, but don't remember them
very well. Likely, the prints are toned for image protection
although there is nothing on the web site to indicate that.
At the prices asked for the prints should be made to the
best archival standards possible.
   Do you live someplace where you can see actual
photographic prints by good photographers?  If so it will be
helpful in knowing the limits of the process and judging
your own work.

My two-bits worth: I see no need for Pyro or anything like it in those
images. The harshest light seems to be in "Sombra, 1999", but it's still
well modulated. (An aside, I want to believe the scans are not an adequate
representation of the tones of the original prints.)

IMHO, Kunh's work shown there is premature. Needs paring.

I'm not sure there's anything unusual about here work. Just looks like
good-quality Hasselblad work to me. You have to start with good lenses
first.

There is, the tonal separation is rather good.., creamy and smooth. It
seems that we have a lot talents here on NG to be discovered......

Anyway, please forget about the original post.

Hmm, 'creamy and smooth' doesn't quite equate to 'tonal separation in my
book.  However:

The secret to both is big negatives and slow film.  No
funky developers, films or papers.

I think I've learned that.  I never thought a 11x14 print from a 4x5
negative could exhibit grain.  But with Fortepan 400 film, I see grain.

   I never know what exactly is meant by tonal separation.
Some seem to mean high contrast, others low contrast, others
just having a good gray scale. In most images it is the
mid-gray tones which are the most important. These are
strongly affected by the characteristic curve of the film
and perhaps a little by the developer. Some films have a
long linear relationship between expsoure and density,
100T-Max and 400T-Max are examples, other films have an
upward sweeping curve, Tri-X sheet film is an example of
this type as were many older "portrait" films. If one makes
negatives of the same subject and prints them for the same
shadow and highlight points the upward sweeping film will
produce darker mid tones than the straight line film. This
is effective for some subjects and not for others. For some
subjects having the mid tones lighter is more appropriate.
  Choice of printing paper also affects the rendition. Some
modern papers have a long toe, meant to lower the contast of
the highlights. Ilford's papers seem to be expecially
noticable this way although Kodak does it on some papers.
The idea is to make it easier to get unblocked highlights
from modern films  which are capable of very high densities.
Such paper can result in somewhat distorted mid tones when
the negative does  not need the highlight compression. To me
Agfa papers have the best "normal" tonal rendition.
  Of course, there is no technical data on Mona Kuhn's web
site. It really doesn't matter how the images were made if
you like them but without the data its impossible to guess
at how they were made. My own impression from the web
pictures is that they are just good quality conventional
prints. My earlier remarks about seeing actual high quality
prints is that digital images can be manipulated to such a
degree that one can not always tell much about the
originals. The quality of a good conventional
"silver-gelatin" print can be superb but many never see
examples of how good the quality can be so may be satisfied
with less than this in their own work.
  The photographic process was developed to make it easy to
use and to be easy to get good quality. B&W should really
not be much more difficult than using a Xerox machine. BUT,
to get good quality you must follow manufacturers
recommendations and avoid exotic processes or techniques.
This may seem like heresy but it really isn't. When I was
learning photography in about junior highschool I had a
couple of mentors. They were knowlegible and meant well but
I discovered much later that much of what they told me and
led me to do was plain wrong. I suffered much frustration at
that time because I did not understand the importance of
controlling negative contrast and because I was using a
rather off the wall developer. It turns out that the
developer probably caused me to have a lot of bad negatives.
I drifted away from photography during my college years but
came back to it later. When I did I decided to begin over. I
bought all standard chemicals, D-76 and Dektol, and followed
the instructions. Voila, perfect prints! Well not all of
them, but I did not have the trouble I had earlier. I used
very similar equipment, about the only significant
improvment was a better enlarging lens but the one I had in
highschool was not a bad one.
  It is amazing to me how much mis-information there is in
photography, it just abounds. The fact is that it is a very
forgiving process so some sort of image will be gotten
almost regardless of what one does. However, its not
difficult to get really good quality. If you follow the
directions in Kodak's little instruction books it will
happen.
  I think the images on Mona Kuhn's wet site are very good
technically, their artistic merit is beyond my competence. I
wish I could ask for and get a couple of thousand bucks for
any of my images:-)

To different people it means different things. For me, it means ideal
mid-tone contrast, above all.

Absolutely, and this is completely ignored in zs dogma.

Especially a problem with outdoor work where foliage is concerned. It
tends to reproduce too dark anyway, when no filter is used.

I could never get good prints on Brovira with a condenser enlarger.
The highlights simply would not print at all. All I got was blank
white.

Precisely. The widespread belief regarding the 'necessity' of using zs

Truly so. Perhaps because it appeals to the non-academic types, who
have never had much class work in science, math, or physics.

Depends in part on the film you use; some films are more insensitive to
green than others. This subjects gets quite complicated because one has to
consider the other colors in the picture frame, and our impressionistic
human interpretation of colors.

I find that so very strange, unless Brovira has changed. The last time I
used it was in the seventies where all we used was Agfa Brovira graded
papers - for example BS 111 (#3 "Special extra white glossy") dried matt. I
used literally thousands of sheets of this paper and have a lot of very good
detailed highlights, and plenty with just off-base-white highlight images.
But I also used careful exposure/development film adjustments. And I was a
very good printer, too. I'm still trying to catch up to where I was then.

Ah, but I was so much older then,

What kind of enlarger did you use?

I tried various grades of Brovira, and all kinds of developers, but
nothing worked. No highlights. Not at all.

It was all 35mm and the enlarger was a Leitz Focomat with either a Nikkor
2.8 or a Focotar - 40mm as I recall.

I'd love to hear what you use personally right now.  Film, developer,
camera, lenses, any special techniques and etc!!

Do you adjust contrast with development?  

How do you develop?  After struggling, I'm finally getting consistent
negatives with trays.   I started with an 8x10 color processing tube.  Had
some success and failures.  Being that I am just starting out, there
are so many variables that I didn't know where my problem was.  But I
realized that the ridges aren't good enough to hold the negative against
the cylinder wall (its a Chromega drum...not Unicolor). After Googling, I
went to the hardware store and bought PVC and caps. White was my only
choice so I spray-painted black. Well they leak and my negatives didn't
turn out for some reason.  I think because they were leaky, I didn't
agitate as much as I should of.  Back to trays...

Never tried it.  The base for these drums work great with Jobo tanks,
though.  This annoys the Jobo rep.

I would suggest getting a Jobo drum, the old 4x5 spiral reels and
a Unicolor motor base.  Used, of course.  My experience is I would
be better off flipping burgers for bucks to pay for the right stuff.

Thank you Richard,

I agree you completel; I agree about Ilford paper, and I never liked
them that much. I think Kuhn's work is fine but I'm really impressed
by the quality. The images has very good tonality (rich, smooth
mid-tones-to-highlights.) It seems that linear curve film- yes it
could be a pulled Tmax in something like microdol. I think that Pyro
produces that kind of curve with coventional films; it was the closest
I got to those images and printed on VC paper- yet was grainy. But I
can't really believe it's an old technology film in one of the
conventional developers like D-76.... I don't know!

  Long thread snipped...

   D-76 is close to being an optimum developer for a lot of
films. It is also pretty fool proof.
   There are a lot of good films on the market although
some have been recently discontinued at lest in some sizes.
The slower the film the more likely they are to give you
smooth tonal rendition. There are several medium speed films
in 120 roll films, Agfa APX 100, Ilford FP-4+, or Kodak
Plus-X all do well. Agfa is the coarsest grain, Plus-X the
finest of the group, not a huge difference. To start try any
of the above and a developer like D-76 diluted 1:1 or Xtol.
   I prefer Agfa papers for printing and Kodak second. I've
used Ilford paper in the past but don't like their current
RC papers. There are good print developers made by all of
the big three. Dektol is of course the old standby. For
somewhat more neutral tones try Ilford Bromophen. Agfa makes
the only Phenidone-Ascorbic acid print developer I know of;
Neutol Plus.
   Process the film according to the instructions. Be
careful of agitation techniques, Kodak recommends 5 seconds
every 30 seconds, Ilford 10 seconds once a minute. They are
not quite the same so follow the agitation given with the
time/temperature chart you are using.
   Even though B&W is not as critical of temperature as
color it is still important to control the temperature if
you want predictible and repeatable development. The
developer temperature should be within on F degree of the
expected temperature. You will note the charts are usualy in
2 F degree steps which tells you that amount of change makes
a significant difference. I use an electronic thermometer
which is calibrated to an accuracy of about 1/2 degree F.
Mine is a CheckTemp made by Hanna Instruments and cost
around $30 US.
  For roll film I use old Nikor stainless steel tanks. I
also have a rare Nikor sheet film tank which I use for 4x5.
I also have used tray development and print drums for sheet
film. Trays are fine for small amounts but I am not the most
skillful film shuffler.
  T-Max films are excellent but are more sensitive to
variations in development. To get a change in contrast of
one paper grade most films need a change of about 33% in
time, T-Max will change taht much in 20% to 25% change in
time. The film is also more sensitive to agitation and to
temperature. If you work carefully you will not have
problems with excessive contrast.
  Kodak charts are for contrast suitable for contact
printing and diffusion enlarging onto Grade 2 paper. In a
condenser enlarger these negatives will print correctly on
Grade 1 paper. If you want to print on Grade 2 you have to
reduce the development time as indicated above and decrease
film speed to about 3/4 of the ISO speed. Ilford gives times
and speeds for a compromise contrast between diffusion and
condenser printing. Agfa seems to use different contrasts
for different charts so you have to look carefully. Agfa
also uses "gamma" a measure of contrast that is not often
used now for pictorial negatives so the numbers are not
directly comparable to those published by either Kodak
(contrast index) or Ilford (average gradient). In any case,
if you follow directions you should be able to figure out
what to do to adjust the negative contrast, or for that
matter, if they need adjustment.
  Because paper is developed to "completion" that is, to
the highest density and contrast it is capable of,
development is less critical than for negatives. However
there IS a change in density with change in development
time. To a very limited degree variations in print
development can be used to compensate for small variations
in exposure. Once you reach full devlopment there is little
change in the contrast of papers despite the existence of
low contrast developers (they are just slower) and variable
contrast developers (good for maybe half a grade). I really
like variable contast paper because I can adjust to get the
best print from each negative. One can do this with graded
paper also but then you need to stock a lot of paper. While
any VC filter set will work with any VC paper the contrast
grades and differences and exposure compensation (so called
constant speed) will be right only for the set supplied by
the paper manufacturer. If you are using a color head each
manufacturer will supply you with a chart showing the
correct settings to obtain the contrast you want. Textured
papers will not give you as much conrast as glossy because
the light scattered from the surface washes out the deep
shadows.
  I develop prints for around 90 seconds to 2 minutes,
depending on the paper. For fiber base paper I sometimes
develop for as long as 3 minutes but like to expose so that
development is complete in around 2 minutes (assuming a
Dektol or Bromophen type developer).
  Get the best enlarging lenses you can afford. With this
exception expensive darkroom equipment is not necessary
(although its nice to have).
  I don't know what else to tell you. There just isn't any
magic. Time and temperature should be accurate, agitation
consistent, and chemicals fresh. Keep things clean.
  I've left out cameras. Film is relativly tollerant of
overexposure, not very tollerant of underexposure. Cameras
should have reasonably accurate shutters (much better in
modern cameras than in the past) and good lenses (not as
much better as you would think).
  Keep records in the darkroom. Note how the prints look
when wet and look at them again the next day when they are
good and dry. Most papers "dry down" or change contrast and
density between wet and dry. This can be compensated for to
some extent but you must learn what the paper does.
  This is turning into a book so I better quit now.

But it is so interesting!!  Thanks for all the great information.

Just one thing:  You say to "follow the instructions".  Are you a true
follower of the zone system in that you always develop your negatives to
print at Grade 2?  I'm just trying to get a feel whether or not I should
carry out development tests, or just rely on VC paper (and of course
expose my shadows appropriately).

Hi,

I'm sure that if we went through the archives, there is enough material
already for a book.  Now the hard part, editing.  ;-)
