Hello,
I use a 2520 tank and 2509N reel to develop film with minimal agitation. I often use B's Processor as well.
However, I get several marks on the edges of the film as shown in the attached photo.
I believe these marks are related to the protrusions in the guide rails of the 2509N reel, but I don't know how to fix this.
If you have a solution to this problem, please advise.
Thanks.
