Help with marks on negative

[Guillaume Zuili]

This is a crop on 8x10 Tri-x processed in Jobo 3005 and Wd2d+
I never had any issue with that. Neg just came back from drum scan and I have these marks. Is it from the fluid ? I'm puzzled.

Help needed ! Thanks

Any clue ? Need a bigger pic ?

What marks? the sort of square pixely looking stuff? Just a low res scan I suspect (or severe cropping)

 

[Guillaume Zuili]

If you click on the square pixely looking stuff you will see the marks.

Yes , I need a larger view, cannot see cleary to make an opinion.

Any clue ? Need a bigger pic ?

I did click on the bigger view. I see a stripe but that could have been caused by scanning.

Are you talking about the 'washed out' parts of the film. Small local density variations?
I have no idea. Sheet film in a Jobo should have even development. I guess the liquid is randomly distributed across the film plane while the tube rotates, correct? Strange...

You'e talking about the horizontal stripey looking marks, right?

If so, I had that problem several years ago. Pre-soaking my film eliminated the problem for me. Did you pre-soak?

Cheryl, I always pre-soak, around 4 minutes. I never had anything like this with my Jobo. I'm quite positive it's the scanning fluid, now I hope that can be removed.
I always shot twice and divide the process. 1th tank get one side of the film holder, the other tank the other side. Just a precaution. From the other tank, the same film which didn't "go to scan" : no mark.
Ok, now it seems that fluid is the problem.
Thanks for your responses.

Guillaume, what is scanning fluid?

 

[Guillaume Zuili]

For drum scan they use some fluid to get a perfect adhesion of the film.
Better resolution, no dust...
It's quite impressive.

The problem might be easier to see if you could print the neg. I'm not sure what it is.

drum scan for a 8X10?

shalom-are you doing billboards?

never knew fluid to leave marks on 35 or 6x6 color chromes

looks like a bad scan to me-the very regular edges preclude dev streaming or fluid marks

i never presoaked b&w more than 1 min-30 sec more ususal-long presoak can cause problems-how deep is tank you are presoaking in-if using daylite paper tube long presoak can cause marks

vaya con dios

 

[Guillaume Zuili]

I might over presoak. Will try shorter time.

I know this is an old topic, but did you ever get those marks to come off? I would have tried rewashing the neg.

 

[Guillaume Zuili]

I did it. No change.
