Staines?

[Serpico]

Dear All,

My last processed films are almost all showing very strange staines - I was thinking about reticulation but it doesn't look like it is the case - do you have an idea what it could be?

Thank you very much

Serpico

Are those from 120 roll film?
Does every frame show the artifacts?
Is all the film the same brand/product?

Depending on the answers to the above questions, I think the first thing that needs to be ruled out is the possibility that there might be a problem with the paper backing ... ?

 

[Serpico]

Hi

it is from the same roll 120 Ilford Delta 100. The staines are almost on each frame but not with same répartition or intensity.
Thanks!

What is paper backing?

 

[Serpico]

By the way what I posted is a scan I obtained from the negatives

What is paper backing?

120 roll film comes to you and attached to and rolled up with backing paper - that paper keeps light from the film when the film is outside the camera.
As it turns out, that backing paper is actually quite complex and difficult to make. In recent years a number of the film manufacturers have had more problems than usual with the film emulsion interacting with the backing paper that it is rolled up with. Those problems are sometimes related to how the film has been handled and stored.
Your "staines" look like some of those problems.

Big up your massive staines.

May be. But I never had such problems before

Yes, that is the backing paper problem. I had exactly the same marks on a roll of Delta 100 over a year ago. I don't have the scans of those negatives on the device I'm using here but it was the same.

keep all information you might still have for the roll, batch number, expiry date etc, and contact Ilford. The information to do so is at this link:

They responded to me, it took a while due to everything being locked down when I contacted them. It should be faster now. My film was replaced, the service is excellent.

Don't worry, that is the comic Sacha Baron Cohen playing his character "Borat" and while he is very funny, he is just about as hard to understand for us English speakers as he would be for a non native English speaker.

Thank you for your message. Very helpful. I was almost sure it was not coming from my chemical baths as I processed 35mm with absolutely no problem at all. I still have one doubt and question - it is clear that it is only happening on 120 rolls but not only Delta 100. I use FP and HP5 and had similar horribles traces on the negatives. Is it possible that not only Delta 100 had paper backing issue?
Thank you

Ok Borat is famous in Europe as well

The problem is not limited to Delta, as it is the paper backing involved, which is used for the different Ilford films. The link I posted will walk you through reporting this.
Since you have scans from FP4 and HP5 showing the same marks, those should also be reported using the online form. I only had problems with the Delta 100, so just reported one film. I do not know if you need to fill the form out each time for the different films, but this could be the case.

 

[Serpico]

Make sense. Thank you
I’ll contact Ilford tomorrow.

That is his Ali G character. He had three that were from his TV show. Ali G actually got a movie first. Borat was the biggest hit.

Thanks for the correction.

Also be sure to mention if you have more unexposed rolls of the effected/defective stock & they should replace those as well.
I need to do fill out their replacement form for some Pan F+ film I recently shot.

I would try taking a picture of your negative with a mobile phone camera. Make sure you see the marks.

Do you see the defects on the film with a magnifying loupe?

Yes - I can see marks very clearly with magnifying loupe. I have unfortunately several films with this problem - Delta 100 500 HP5 FP4.

 

[Andrew O'Neill]

That's backing paper issue. How fresh is the Delta 100?

 

[Serpico]

I have used used films from two lots
From Lot exp Jan 2020 and from lot expiring nov 2021
