[expert? ] ARGH! strange effect on negatives

IIRC, your last "ARGH" was 'corrected' by using a more correct
agitation in the fixer.
Nice brain Dan!

Was that a coincidence?

yeps.
Are you up against a one in one million few rolls of film.

usually i take lot of care.
and when it happens someting like this i feel confused...

Before I forget, I think 8 minutes in film strength rapid fix is
to much.
yes, I'm starting to think too. Or the tempeareture of fixing was
increased more than 23°C form some reason... test test i've to male
tests...

Before I forget, I think 8 minutes in film strength rapid fix is
to much.
But sometimes a 5min of fix don't cleart the antihalo magenta stain
enough. And, since this would give no problems in negatives life,
sometime creates lots of problems in printing because increase contrast.
Plus, sometimes a long time of washing not solve the magenta stain.
All of my negatives have to be gray on the border: And so they are 98%
of my negatives.


Back to the film, two films are making trouble. What do they have
in common; date of purchase, storage, transport, place of
purchase, etc?
The same film buyed in pack of ten:
Neopan 400 35mm fresh.

I think you are an experienced film processor with a mystery to
solve.


Hope I will do.
I will solve this mistery with a saturday of testings and following some
sugestions, like these writed by many mates in this NG.
Thanks people.

Hope my questions will help someone.
Sorry for posting strange problems.

This time i feel the surface like satin, with some noise when touching.
Like touching a very fine sand.
First time in 12 years, again.
under strong magnification under my Durst "sandy surface" it seems like
bubbles, everywhere in hilights and in low lights indifferently.

Perhaps something happened to stir up sediments (rust, calcium
precipitates, foreign debris) in your water supply.

Our local newspaper periodically contains an announcement about the
fire department routinely flushing the hydrants in a neighborhood, and
warns that red (rusty) sediments will appear in the tap water of that
neighborhood. Yes, indeed, there was crud appearing in my tap water.

I experienced a run of many (ten, fifteen) years without problems, but
on one memorable occasion, a series of eight rolls were damaged when
sediments suddenly came gushing out of the tap during my developing
run.

After that disaster, I now attach a filter unit to my darkroom tap.

Hallo.
this week another error or strange effect on a negative. This time is
very very difficult to understand.

Negative was Neopan 400
developed in Microphen 1+1 7'30" @ 20°C
stop in water
fix with Ilford RapidFix 8'
washed for 10'
Once

The negative has perfect contrast, density and so forth.
+Once dryed so the negative looks quite good
but the real problem is the emulsion side surface.
Usually this surface is quite smoot, not glossy like the other side, but
smooth.
This time i feel the surface like satin, with some noise when touching.

First time in 12 years, again.

Once printed here are some results.

Pics are quite heavy and large to allow a good vision of the problem.


I need some serious help because this error in a batch of 4 roll it
happens everytime in different intensity. But it happens and pratically
my films are useless...

Are this lot of film defective?
Are this films burned by something in developing? No acid stop and
normal fixing time was used.

In the meantime i'm testing another kind of batch of strips of this film
to test with Ilfosol and ID-11 as my usual developers...

HELP!!

How is your water quality? Was there a recent change in the water line
plumbing prior to your darkroom? If you are on a city water supply, was
there a water line break somewhere "upstream" from you?
The first film I developed in my latest darkroom (years ago) had a "gritty"
feel to it. I added a water filter and that solved the problem. (At first I
added a faucet-mounted filter. Later, when the water heater gave out because
of sediment in the water, I added a whole-house filter.)

Very little water is needed to process a roll of film. Use distilled
through-out the film's processing. Dan

I think the problem was solved!!
YO!

Good! What was it? And do not apologise for asking strange questions,
They are more fun than familiar questions.

In few words was strong solution of fixer and anomalous time and
temperature. After a whole sunday passed for test the results are in the
foollowing words...

the reply post is already published but I want to rewrite here for
courtesy:
-----------------
I have done today four tests, with four different developers, new fix
and reduced fix time. Like you suggested there is something wrong in
fix... test test test!! Alone in the dark testing today!! Is a rainy
day!!

I really think that the negative was destroyed by two differents factors
at the same time.

First of all I was helped by a friend in preparing the fix solution and
other stuff, bEcause he was a friends who wanted to learn more on
photography, ok?

First reason:
He says to me that he did fix solution slightly more concentrated than
usual, like I use to do. But alot more concentrated: 1:3 instead
instead **1+3,5** that is very different with rapid fixers. So I think
that more acidic environment subtle wounded the emoulsion. Then a
excessive fixing time: 10' instead of 5'-7,5' as I do when FRESH.
More fixing time and concentration, this time and with this rolls, not
did more bleach on highlits, like many books says but makes like burns
and bubbles on the emulsion.

Second reason:
not stable water temperature.
usually in my lab there is always 24°C. This time i can see that there
are a couple of °C more high and low. But i beleieve that this cannot
affect at all the washing but can help in desruption of film.

Sorry people for using NG as reporting my esperiments, but after this i
feel more sure of my self (and of course, less of my learning friend....
)

Today tests results with as usual stock treatments?
Perfect negatives... and I feel more comfortable with myself!
--------------------------

;D

Ciao,
Stefano
