Hi Everyone, new here so not sure what I'm doing. Developed a roll of delta 400 last night and got these strange blotchy marks
on the negatives never seen it before. Thanks for any help

Welcome to Photo. Sorry about the problem. Ruins a pretty good photo.

What format is this? How old is it, and how was it stored? If 120, it can be mottling due to backing paper, but that problem was fixed by Ilford a while back.

Hi Alex, thanks for your response its 120. I thought maybe it could be that. It did expire in 2022 but it was stored in the fridge. Developer was Rodinal 1:50

The mottling may have more to do with humidity or moisture than expiration date.

Thanks Greg, the joys of working with film. Somebody is not going to be happy

He already didn't seem too happy

I believe the recommendation for using film out of the fridge is to wait an hour or two before putting it in the camera.

Yes, that's been my understanding as well.

Ilford/Harman has adressed the problem on this web-site ( enclosed ) .

Updated 120 ROLL FILM STATEMENT

In March 2020 we issued a statement in relation to instances of spots / mottle affecting a small percentage of 120 roll film negatives.

Also, film should be kept in the wrap. I've seen quite a few rolls where wrap was removed and stored without it.

I'm also using large ziplock bags for a number of rolls as a precaution when storing in the fridge/freezer.
Bags will preserve the outer packaging.
