I'm having some problems with my last Fomapan 100 batch; its number is 017754-04. As you can see in the image
in some areas, gelatin has scratches and I don't know from where they come.
My fixer is sodium thiosulphate I mix on my own; no hardener added.
Do you think is a quality issue? How can I know if there are more sheets damaged in the box?
