I am looking for your opinions, please reply if you can. I am looking
for sharp, contrasty negatives, little grain, using B&W film. Please
suggest what film developer, film combination I should use to obtain
above.
I printed some 8 x 10's last week from Ilford B&W negs. ISO 125 Fp4+ in
Rodinal 1:50 for 8.5 min.
I can definately see 'the grain'. The 8 x 10's are sharp, however. I am
wondering whether I should be seeing grain at all. I was expecting this
combination to result in very fine / little grain.
I have done some prints with Kodak 400 CN film (B&W using C-41 process)
and 8 x 10's are super super sharp, no grain, however they need more
filters for contrast. Should I even compare the two films for sharpness
and graininess?
I also have Ilford Ilfosol-S film developer. Maybe this will give the
results I am looking for.

Of course you will see grain from a ASA 100-125 film in an 8x10 if you are
talking 35mm as the fim size. Why do you think people use medium and large
format cameras if 35mm negs had the fine grain and high sharpness
necessary? 35mm is really a small format film. It is generally the choice
for journalists due to the smaller camera size. If you want fine grain you
should try the slower (PanX) varieties of 35mm film or try renting a medium
format camera just to see the difference a larger negative actually makes.
On the subject of development alone, I have heard that Rodinal is actually
reputed to be used when graininess is DESIRED for effect. It delivers
rather long tonal ranges which I like, however (I use the 1:25 dilution).
Also, sharpness and graininess do NOT go hand in hand: you can have a
grainy developer with high accutance (which to me is more important than
grain). I don't know why I think this, but for fine grain I might suggest
Microdol used straight for fine grain with contrasty negs. Bear in mind
this is from my past darkroom experience and I am getting back into
developing after an extended absence.

The two films are not the same ... one is conventional black and white, the
other C41. The C-41 film is designed for people who do not develop their
own film; they can take it to their corner photomat that processes C-41 and
they will get back black and white prints. However, "real" conventional
black and white film it is not.

I agree with the other poster that people use Rodinal when they *want*
noticeable grain. Might I suggest that you use the same speed film,
either Ilford's ro Kodak Plus-X, then use Microdol-X 1:3. Some people
say that Microdol-X causes a loss of sharpness, but I don't beleive
them. I did some testing (subjective, however), and I found very little
difference in sharpness between negatives developed in Microdol-X 1:3 and
those developed in D-76. You do see a little loss in film speed, about
1/2 stop to a stop, but I find that to be not too objectionable. Microdol
is an inherently un-contrasty, but you can increase contrast by increasing
development time.
Regardless of the film format that you use, you will get less grainy relults
with Microdol-X.
Good luck,

1)There are other fine grain developers you can try as well in addition to
microdol but I suspect the results will be about the same.
2)Try a more dillute solutiuon of Rodinal. 1:100 is what I use when I want to
bring otu the full potential of the film and the developer.
3)Consider a different film. If your goal is maximum sharpness then the
slowest, finest grained film you can find is a good starting point. The
ultimate is Kodak Tech Pan (which requires a special developer for continuous
tone negs) or EFKE R 25. I ahve been using the EFKE whenever I could get it
for many years and find that it, developed in either Microdolor Rodinal 1:100
depending on what I am shooting, gives me the best I can get from 35mm.
4)Remember that even at 8x10 there are many variables taht will ahve a major
impact. Camera movement, lens quality, etc. All by way of saying it is a tiny
negative and requires a lot of work for large enlargement ... if max sharpness
at sizes larger than 8x10 is your goal you might want to consider starting with
a narlger negative.

Microdol-X, when diluted to 1:3 has considerable edge effects so is
a pretty sharp developer. It also looses its extra fine grain
qualities when used diluted. At 1:3 its grain and speed
characteristics are about the same as for D-76.
When used full strength it has little edge effect so does not
produce the actance effect it has at 1:3 and which is a characteristic
of diluted Rodinal. It does have very fine grain, although I find it
only slightly finer than D-76. It also looses about 3/4 stop of speed.
These effects are due to the very low activity of the developer and
its fairly high sulfite content.

Rodinal is definitely not a developer to use if fine grain is a desirabble
result.
A decent compromise is to use Rodinal 1:75, with about a 5% soldium sulfite
solution, rather than plain water.
If I recall, about twelve-fourteen minutes ought to be about right with FP-4.

From prior description, it sounds like the old Adox KR14, a film made in
Germany until sometime in the early '70s by Adox. Of the three B&W films Adox
made, this one had a slightly non-panchromic senstivity which some people
liked for its unique perfomance. Very fine grained and sharp, but very slow,
similar to Panatomic-X of the same vintige. EFKE acquired the license to make
the old Adox KB/KR 21, a conventional film of the same period similar to
Plus-X, but this is the first time I've heard that they were making another of
the old Adox films - would like to hear more and find a source to try some.
Since EFKE is in the former Yugoslavia, there is some possiblity that the
political and economic problems of that region may terminate this thread.
NOW what I would like is for them to ressurect ADOX's old ISO 12 speed film ...
the finest grain B&W film ever made. I jsut ordered some of the 25 and will
let everyone kow how it performs.

Efke is brand name of Fotokemika which was always (and still is) in Zagreb,

it did not move, only the borders changed.

In fact, I developed a roll of HP5+ this morning using Ilford's
Ilfosol-S, because I'd been using it before -- and my kids have been
using it in my darkroom -- with some pretty nice results. It seems
that the grain is not nearly as pronounced with the Ilfosol-S diluted
(1:9) as it is when I use Rodinal! -Dave

Hi
I think we are comparing apples and oranges
First, sharpness is a subjective impression that has little to do with fine
grain, it has to do more with high acutance.
Any high acutance developer will give the impression of sharpness,
regardless of the actual size of grain. Besides, almost all high acutance
developers are known for building some sort of grain onto the negative.
On the other side, fine grain developers are known mainly for poor acutance
( reduced *sharpness* )
If anybody knows a developer with high acutance, building fine grain onto
the negative, showing full gradient of densities Ilford FP4 is capable, I
want to hear about it.

Sharpness per se is NOT a subjective impression. It is
measurable and definable both with instruments and mathematically.

All that I know of enhance the perception of sharpness through
exaggerated adjacency effects.

This is not accurate and in fact Dr. Richard Henry proved as
much by taking measurements with a micro-densitometer. The results can
be read in "Controls in Black & White Photography" .

D-76 has worked well for quite some time. 1:1 is about as good
as it gets. My advice is to simply get a bigger camera. Eliminate the
petty obstacles and get on with photography.

Calbe Fotochemie makes the R09, which is the same as Rodinal and the
published the following table which is based on times for 1+40.
Delut. 1+20 1+60 1+80 1+100 1+150 1+200
Faktor 0.5 1.5 2.0 3.0 4.0 6.0
They recommend 8-10 min. for APX 400 with 1+40.

I would avoid developers like Microdol-X even diluted since they gain their
"finer grain" by disolving some of the silver halide-include some of the image.
The acutance of such negatives is less than those of the above named
developers, and far less than Rodinal (which I would only use at very high
dilutions with 25-50 ISO films.
I'd tend to think most films-and problems people have with tonality and
sharpness and grain-are over developed, over agitated, and the temperatures of
all the solutions and washes are not kept constant at the same degree, and the
negatives are often dried very quickly with high heat.
It's just thatmany dark room workers often do not take the care they need to
to have the best quality negative. Jim

Of course, the best means of finding the answer is to try it with your
film and equipment. If the resulting negatives appear underdeveloped
after they were exposed at an appropriate EI, then you probably need to
either increase the volume of working solution or decrease the dilution
rate.

I called up Agfa in Leverkusen and what they said is exactly what you can
read above.
I know people who think that 3ml per film is sufficient, but I have not
tried this myself. And I guess it also depends on what film you use.
