I developed five sheets of film in my 3010 drum for the first time this weekend. I used the recomended amount of chemical. The result was that three of the sh eets of film had a purple spot on one of the long sides close to the edge near t he center. I find it curious that all three of the sheets of film had the spot near the same general area. I put the film in the drum per JOBO instructions. Any thoughts?
