I developed yesterday different films, FP4+ and HP5+, in the same badge of ID-11 @1+1. The FP4+ came out as usual but the HP5+ has a hughe stain?
On the picture the upper film is FP4+ and the other the HP5+.
For both I used the same stop aswel the fixer. To be precise a Buffered Stop Bath and a Alkaline Fixer like TF3.
I'am very surprised with this result.
But how is this possible?
And why only HP5+?
Is there also a possibilty to remove this stain.
Any help is welcome.
