Hmmm... I am wondering if anyone else has experienced this. I have always used Paterson 3-reel tanks. I am careful and consistent with every facet of my development regimen. As a result, for a couple of decades, I have always had consistent results. Finally, I just needed to get more film proceesed faster so I switched to a Paterson 5-reel tank. I have just finished my fourth 5-reel session and I am slowly starting to suspect that not all of the reels are seeing the same amount of development. I develop for 9.5 minutes in D-76 at 1:1 with three quick inversions every 30 seconds. Is this possible or am I just imagining things?

Thanks, JK
