Over the last 6 weeks I have walked passed and stumbled over the solution to the problem with getting my recalibrated prps. I was doing well BTZs until I started using delta 100. unfortunately I had 2 boxes(25sheet and 100sheet). I tested the 25 sheet box but loaded some of 100 sheet into film holders. All of a sudden things were way off. I blamed my spot meter and off it went for recal. Meanwhile i unwittingly used film from both boxes and got extremely different results. Back to the lab with only 50 sheets of the 100 i decided to have a go of re-re-calibrating. I began tossing D76, Xtol and DDx thinking my stock had gone bad until I noticed that my son used the same stock of devels as I did for his college photo class and got good results. After searching the net I read an account of another befuddled guy using delta and having very simular problems. his solution was to switch films. what I did was to run through the whole process again with 100Tmax, and both boxes of delta concommittently. wouldn't you know it, the Tmax test and the 4 sheets of the 25box, perfect! The 100 sheet box THE PROBLEM !!!!! Believe it or not the ei for that box of delta 100(I double checked the ID cuts) is in the range of 800! For a while I truly was BTZS (beyond twilight zone stuck)! I can finaly close this chapter and move on.
