Thanks Tony. First, I usually use Ilford or Agfa, depending on what's on special at the time of buying. I have been using them for a long time (longer than I have been learning to develop my own) and have never had a problem. And since learning to develop on my own, I usually use Ilford developer. I use the 100 ASA film for outdoors and I use the the 400 for indoors/lower light and sports. I have had no problems at all before these last 7 rolls. My meter is in the camera and I do not think anything is wrong with it. In between these 7 B&W films that I have messed up, I also took 4 colour, which I got developed at a photography store, and they were fine. My batteries were fresh.(posted 8881 days ago)The frame edge of the negatives is still sharp. The whole film, including the lead-in edges, and area outside the actual exposed area (where the socket holes are), is a dark sort of creamy brown colour with what looks like a fine grain of sand over everything when you look at it through a lupe.
As I mentioned above, I usually use Ilford developer to process my film, but because I had some agfa film and needed new developer, decided to try the agfa developer. When I saw the results, I thought that I did something wrong with the Agfa developer, threw it out and went out and got what I was accustomed to using, which was the Ilford. But again, same results. I then thought I might have let light into the room when I was putting the films into the cannister, so I used another room that I was pretty sure was 100% a dark room! and processed with Ilford again. Same results. I have used the manufacturer's recommendations for everything. I double checked the temperatures before mixing. I can see that below the darkness and graininess the photographs still look like they should print, but when I tried printing it looked like grains of fine sand over the photograph.
