Hi, I have been experimenting with developing by inpsection and yesterday I tried so me pinakryptol yellow desensetizing agent. I diluted it 1:2000 and soaked my neg atives in it for 3 minutes and then rinsed before developing in HC110 1:60 using Phil Bards negative holder in a tray. According to the little information that I have about this, it should increase development time by 25%. So I increased my time by 25%also developed a step wedge to check and see if it was true, and wha t I found was that it did not seem to lengthen the development time at all. My n egs were all 25% overdeveloped. It did seem to work as a desentisizer as I used a 20 watt bulb in my green safelight and it was only about 2 feet away from the film for about 2-3 minutes and I did not notice any fogging. I wonder if anyone else is using pinakryptol and what have been your experiencesa,and where could I get more information. I also wanted to share what I had learned as seems like i t could be valuable information. Thanks for all your help.
