Analysis and advice needed.

Camera was IIIA; lens was LTM 50mm Summicron; film was Lomo 100; C41 Kit was Unicolor (Powder.) Processing was accomplished in JOBO rotary processor. Scan was made using PrimeFilm 7200.

 

While my advance in color processing has been slow, it has been steady.....Then this roll. I am curious if any of those in the "Know" have seen this before and are able to help me figure out what went wrong. There are some dust inclusions, but the vast majority of the galaxy of white spots are not related to dust. The problem is present in the entire roll, affecting all shots equally. This one illustrates the problem best.

Hard to tell from distance.

I have a similar problem with some old Fuji Reala films, the expired about 2008 and stay well cooled in the fridge for years. Since the colours are quite exceptable they develop a lot of small deposits on the backside that showed up as white spots. Fortunately you can carefully wash them away with alcohol. Other films, developed in the same run didn't show this effect. I don't know the reason for this and if this might be the same here, but if you wipe it off you got a clean negative.

If I look on the reflection of a window for example on the backside of the film I can see that there are deposits.

To remove it I place the film backside up on a cleaned glass plate. Than I moisten a hanker-chief with a drop of alcohol and move it once or twice in one direction over the film. Never rub on the side of the layer! And don't let the layer get wet.

 

But of course there might be other reasons for that also.

Can't help with colour diagnosis, I am too scared to even try it, so take my hat off to you (and rpavich as well).

 

I did get a roll of shocking spots a while back, in my case it was old sedimented fixer, which I promptly but too lately, threw out.

B&W film of some description, but old Agifix. Since mixing new fix, no problem.

 

Could this be the problem you have?

 

Like fotomas says, hard to tell from this sample.

Would your entire temperatures be close to each other, so as to dispel the reticulation theory Pico suggests?

Now, back home I searched for an example of what I mean. Looks a bit different, so I guess it must be something else.

Not well solved chemicals maybe or limescale from hard water...

 

Here the example from my Reala trouble:

Hmmmm, can't help you with this then, my snotty fixer issue was spots, not streaks.

 

I have had a slightly less noticeable version of this from local commercial development, which I put down to less than clean rollers, in the processing machine.

 

I hark back to the dip and dunk days, where this wasn't usually an issue.

Good luck.

Thank you Gary,

Luckily I have a solution for this problem, as described above. It must be something with this type of film, since only Reala's are affected, even if developed together with others.
Just post the image, for comparison with the issue of the TO to proof if it might be the same problem.

 

Regards

Fotomas partial reason  : film out of date ? another questions :  it happens on the entire roll

or only on some pictures ? Try another roll of color Fuji

 

To answer Wayne , I also dev myself color film (Kodak Portra 160 and 400) but in "manual" tank

Paterson and I never have this problem you are. Have you this also in b&w and do you use the same

tank processor ?

Color looks fine in your picture.Have you these little spots on all the roll ? may be try another

roll to see. Temperature and agitation correct ? another questions : rev and fix new or used ?

If used , how many rolls you dev. for 1 liter ? . Normaly if high Isos (400) , the rev. is quickly used !

not the case if it's low Isos (160)

I did have the problem throughout the roll. Although I was confident the chemistry should not have expired- either by time or use- I went ahead and mixed another batch of C-41 chemicals. Have not had a repeat of the problem. In this,  i.e new, instance of mixing chemistry I used distilled water for purpose of mixing stablizer. Additionally, and for the first time, mixed developer and Blix at elevated temperature. I seem to be getting better results now.

 

Thanks again for attention and comments.
