Is this the film or the camera?

Dear Friends,

I took sone Trix rolls for negative development. Out of 10 rolls I gave some ten frame that came out like this. Not in sequence and not in the same roll. According to your view, what is this? Is it the film development or the camera (M7)? 

Many thanks for your feedback, Giulio

Very difficult to be sure without seeing the whole negative but it looks like the film has been badly developed or badly scanned.

Many thanks, it seems it's the scanner. I tried to re-scan the defective files and they came out ok. My bad for not having thought about the scanner.

I rescan the files with a different software and they came out fine. It was the dust and scratch removal which was creating problems. Thank you

Yes, dust and scratch removal software doesn't work on silver based B&W films with any scanner, the only B&W film that you can use it with is Ilford XP2 which is a chromogenic film similar to colour film which is processed in the same C41 chemistry.

Thank you, I was not aware. However, the rest of the ten rolls came out fine

There's a lot been written over the years about dust and scratch removal software not working on silver based films.
