This is an anomaly that I'm trying to track down. Film is HP5+, 4x10, processed in PMK. This is the second type of mark like this I have had on my film recently. I mark my holders and thought it might have been a pinhole on the darkslide. I do not see one when I inspect it with a backlight. Have you guy seen this before? The streak is on the film, and is not on the duplicate exposure on the other side of the holder, so I know it's either with the darkslide or the holder.
This is the second time I've had this recently. Not an artifact from the scanner...it's not on the duplicate image on the other side of the holder.
EDIT: Some additional information-
These two negatives were shot within a week of each other and came from the same box of Ilford cut 4x10 film. Both negatives were processed in a JOBO 3005 drum with PMK that I mix myself. They were not processed together in the same run, but were processed with the same batch of PMK. These are the only two negatives out of hundreds of sheets of 4x10 that I've shot and processed lately. I continue to have total faith and confidence in Ilford products.
Thoughts?
