I have recently encountered some strange defects after developing some 8x10 Ilford HP5+ film. I have exposed and developed around 2000 sheets of Ilford 8x10 film over the past 10+ years and have never seen this problem until now. I have attached a couple images with the negative with the most pronounced defect. I purchased a box of the film from B&H in New York and around 8 out of the 25 sheets had these artifacts. They look almost like a drip spot. They were immediately apparent after development, when the film was still wet, so they're not due to drying. They were never in the same place in the negative, but tended to be in consecutive sheets as packaged in the box. The areas of extra density are not visible when the film is held at an angle, so they are embedded within the emulsion. The film was developed in freshly mixed Kodak D-76 developer and put through Ilford stop and rapid fixer. They were tray developed on at a time, using brush development, in complete darkness, the same way I've developed all of my sheet film. My camera (Deardorff) and film holders have been thorough checked for light leaks and are fine.
The dark ring in the upper right corner is due to a fence in the field of view.
Any thoughts on what this could be? I sent a message to Ilford, but they don't have an option for uploading images.
Thanks.
