I'm familiar with Rodinal and was just wondering if Paterson's Acutol
is similar, or a different bird altogether.
Jorge Omar - 22 Mar 2004 22:30 GMT
AFAIK they are two different species.

Anyone care to address their relative differences?  I'm getting ready
to do some film/dev. calibrations for FP4 (120) and have been
considering these 2.  As it stands, I may stick to D76, which is what
I've used for HP5+ (35mm).  I'd welcome any opinions.

Acutol is far superior to D76 or Rodinal.

Not even close.

Try 1+14 for about 7-8 minutes, depending on whether you use a
condenser enlarger or diffusion.

Acutol is a completely differnt kind of formulation, and is vastly
superior to Rodinal.

Hey! Some guy named Hans Beckert is saying the exact thing on Photo.net.
Isn't that a coincidence!

Do you know that guy, Hans? err, I mean, do you know Hans, Mike?

Yep, same arrogance covering up for a poor understanding of photographic
materials. Too bad so many newbies have had to be corrected after receiving
your faulty advice.

C'mon Mike/Hans, don't be such a slimy little pussy! 'fess up! What is your
real name?

Rumor has it several moderators are thinking of banning you completely from
Photo.net. That would make sense, as less dogma and inaccurate information
are always striven for.

But please, please Mike/Hans, post that poorly exposed, badly composed, and
unsightly rhino picture again! Nothing like a real life example of your
skills.

 Good Grief, try and get a simple answer out of this group anymore.

 How bout the guy with the understanding of photographic materials?

 Both Acutol and Rodinal are considered accuntence developers, so what's
 the difference? I ask because B&H cannot ship Rodinal, and I'm in the boonies.

They make a Rodinal version and you can also buy the parts and make it
yourself.

    Agreed. With Richard, Michael and so many others gone, it's
hardly worth the bother anymore. Unfortunately what is left are a few
with more opinions than facts.

    Unfortunately I've never used Acutol but from the comments
I've read I wouldn't put it in the same group of formulas as Rodinal.
More like Microphen/ID-68. Slight speed increase and an increase in
granularity when compared with D-76.

>  Day Four and counting.

    Don't let the lack of good contribution annoy you so. It's not
worth it.

I've never used Acutol, but I will give you my viewpoint (straight...)
Acutol was formulated by Crawley, of FX-1, FX-2, etc fame, so it's a
modern developer, quite possibly with the same accutance but less grainy
than Rodinal (I've used Rodinal with 35mm film for grain effects).
If you consider less grain important, go for Acutol.
If you do not, and want the Rodinal look, J&C
(http://www.jandcphotography.com/) will ship the R09, stated as an pre-
WW2 version of Rodinal, made in the ex-western Germany.

Pick your choice.

Acutol is quite different chemically and in its effects from FX-1 or
FX-2. It does not compress mid-tones the way those do. It is sharper
and finer-grained than Rodinal.

Hello:-)

There is also a Rodinal version made by Foma from Czech Republic, Fomadon
R09.
http://www.foma.cz

I've used it for a year or two. The bottle I once bought had been out of
date for a year but it worked well, for half the price;-)
It's great with APX100 and works fine with other films. I've used it mainly
in 1:100 dilution, and times for Rodinal.
I've also tried Acutol recently, but I haven't made many prints from TMY and
FP4+ developed with it, so I won't comment it and compare with R09.

I'm just about to buy it:-) From what I've heard, it hasn't been available
in Poland for some time, but now it seems to be. I've read that it's a copy
of X-tol. A friend of my recommended W-27 with Neopan 400.
Besides R09, I also tried W-17, a copy of Microphen, but just twice.

i'm using bulk fomapan 100 film with foma chemistry
fomadon excel + fomafix rapid
tried fomapan 400 but disliked it for "pale" & "soft grainy" (after 100 ;))
look

thanks for info

It seems to have. Mine was kept in half full bottle for a couple of months
and still worked. The second bottle's expiration date was around 2002, but
my friend tested it recently. Everything's ok. Grain from Ilfordpan 400 is
hardly visible on a 13x18cm print(usually I don't enlarge more). It's sharp.

I don't know, it was my first developer ever used:-), but then I sticked to
R09, because of convenience.

i'm too short (greedy?) of chemicals so i can't test it really
the only thing i'm sure about it:
it works the same after been stored at 20C/dark/plastic-bottle for 2 weeks
here (moscow) they're selling it in 1L boxes
it's really "fine grain" at least compared to common local developer

Rodinal was formulated in 1881, and is composed of para-aminophenol
developing agent activated by potassium hydroxide, and is quite stable
for a long period of time. It is not a very 'refined' developer, and
is not optimized for modern films. Acutol dates from 1961, and is
optimized for modern conventional films. Acutol uses Metol and
hydroquinone, and perhaps phenidone. It offers finer grain, more
speed, better sharpness, and better tonality than Rodinal. Rodinal is
better-known, but inferior.
Severi Salminen - 26 Mar 2004 17:24 GMT
> Rodinal is better-known, but inferior.

Actually that is not true - again. Rodinal offers bigger (maybe even
sharper) grain, better tonality (as you can see, this is 100%
subjective), more shelf life, much more capacity, is cheaper to use and
availability is very good. And for larger negatives the acutance and
sharpness is completely sufficient for all situations. Whether a photo
is good or not depends totally on other things...

Whether it is better or worse than some other developer is up to the
user in question - up to his/her preferences. This is not that black and
white as you allways seem to think :)

    Don't forget versatility. Rodinal can be used to develop Tech
Pan and other high contrast films when used at the 1:100 dilution.
Also it has been reported to work as a good warm-tone paper developer
when used at the 1:4 dilutions.

Acutol can also be used with TechPan, when diluted suitably.

'Cheaper' I grant, but nought else. Acutol is superior to Rodinal in
all other respects. Do a comparison yourself and see.

No. Since scarpitti says acutol is superior to rodinal I'm going to take
it as a matter of faith that rodinal is superior in every way. There two
reasons for this. The first is that I've seen prints made from 4x5 negatives
enlarged to 16x20 and the results needed to be seen to be believed. The
second is scarpitti's track record.

Lessee: no WMD in Iraq. No connection between Iraq and 9/11. Haven't caught
Bin Laden. Now we hear *from his own "antiterrorism" chief that he was
basically asleep at the switch. Let his buddies at Halliburton get rich off
the war in Iraq. Economy going down the toilet (spending down one of the
biggest *surpluses* in U.S. history). Underlings at the White House are
starting to trip over each other's lies.

So just how far are you, Mr. Frank Lemming, willing to follow our Fearless

Although there's no way to know for sure but I'll bet more libs listen to Rush

he was far to liberal for my liking. I don't listen much anymore and I never go

You took exception to a side issue but still didn't answer my question, which
is how far you're willing to buy the lies and deceptions and incompetencies of

    The better what is the question. They're both politicians. The

So you only agree on cost. Ok, let me see... Are you saying that the next
_is_ true (it is the opposite what I wrote above):

1. Rodinal gives smaller grain than Acutol.

- I think you said yourself that _Acutol_ gives smaller grain. Go figure...

2. Acutol can be used when diluted to 1 + 200 or even more.

- Looking at Paterson site they only list 1+19 as a usable dilution. I'd be
surprised if 1 + 200 works well. Does it?

3. Acutol lasts longer than (say) 15 years in opened bottle.

4. A 500ml bottle of Acutol can process over 100 films.

- Well, if 5ml of Actol is enough for one roll of film, then it is possible.
That would also need about 1 + 50 dilution.

5. Acutol can be bought from Anttila here in Finland.

- I know it can't...

So again I must say that you are wrong. Rodinal is actually superior to
Acutol and I encourage everyone to at least try it.

Correct. Acutol gives finer grain than Rodinal.

> 2. Acutol can be used when diluted to 1 + 200 or even more.

No, the range is 1+9 to about 1+25 or so.

It is not suitable for that dilution, except perhaps with TechPan or
similar films.

> 3. Acutol lasts longer than (say) 15 years in opened bottle.

Rodinal is very stable. Acutol is like most other metol-htdroquinone
developers.

Buy the 1000ml bottles.

Superior in what way? Cheapness? Longevity? These are not
photographically significant features.

      Pardoni, that's acutance. Where was my mind?

   If it is not a p-aminophenol, Rodinal, type it is most likely a
a metol, FX-1 - Beutler, type.
   A little sulfite, metol, and carbonate and you're set to go.  Dan

Acutol is not based on FX-1, it has hydroquinone, metol, etc....
Norman Worth - 30 Mar 2004 04:51 GMT
Acutol-S (also known as FX 15) is a solvent developer based on Metol,
hydroquinone, and Phenidone.  It is derived from D-76.  The current Acutol
may be a slightly different beast, but I suspect it shares the heritage.
The properties are similar, but it is supposed to have better sharpness,
which may mean less solvent.  Traditional Rodinol is a non-solvent,
p-aminiphenol based developer.  The commercially available version from Agfa
is proprietary, and it probably differs from the published formulas.
Non-solvent developers tend to be somewhat sharper than solvent developers,
but they have much more noticeable grain.  Both Acutol and FX 15 have
excellent sharpness, however (as does D-76).  I feel the solvent developers
give a smoother tonality, and I prefer them, but that's a personal choice.

Acutol preceded Acutol-S. I first used Acutol in the 60's IIRC. Acutol
is not FX-15. I think it's formula is still proprietary.

There is no unique connection between solvent content and smoothness or
granularity or sharpness. A sulfite-free developer may have all those
qualities.

Acutol-S is no longer available, and was similar to the published
formula FX-15. Acutol and Acutol-S are not related except in name.
