    I've got a stain with HP5+ developed in ID-11

    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.
    Thanks

    Was the stain visible after the fixing? If not, the stain could be due to the water wash. You can attempt to clean off this stain with PEC-12. To quote...

    "Photographic Emulsion Cleaner for color & black and white prints, slides and negatives. PEC-12 removes ink, finger oils, adhesives, mildew and other non-water based stains."

    I've used it and it is great stuff.

    There's no stain on the bottom image just base fog. It looks quite normal. Don't expect two different film bases to look the same even from the same manufacturer.

    I'll join in. No use going against the majority.

    Upon further inspection, the stain appears to be a general stain and not something acquired through an improper wash.

    IIRC HP5+ has higher base density than FP4+. This is not development fog, but in the base itself for the purpose of preventing light piping through the leader that sticks out of the cartridge. Faster films need denser base. There are other ways of preventing piping. I believe in some films the antihalation coating serves the same purpose and is removed in processing. To test this, take a piece of leader and remove the emulsion from it with full strength Clorox-type bleach. Compare HP5+ and FP4+ this way.
