I'm having a problem lately that i never had before , i have a strange line's over my 4x5 b&w sheets after developing .
I was developing with Paterson tank and a special insert that i found over the net for 4x5 sheets. And next week i bought yankee square developing box for 12 4x5 sheet's. ( which is very nice for developing i got to admit, very easy to use)
i'm attaching 2 images with these line, so maybe you can tell me if it's the developing problem or something else.
