When I set up my little B&W darkroom area several months ago, I decided to use the Jobo CPE2 that I bought years ago to process E-6. The convenience and self-contained aspects and hands-off agitation were attractive. I had misgivings about rotary processing B&W, that the constant active agitation would cause the highlights to over develop while leaving the shadows in the dust. I know that better photographers than I are getting fine results but I find that I have to rate my film one or two stops lower just to get some detail into the shadows and then I have to reduce my developing times by 30% just to keep the highlights from blocking up. I give up. It is time to simplify. I dug out my Nikkor tanks and Stainless Steel reels. Invertable or using a lift rod, I think that those rests in between brief agitations are essential to holding down the highlights and allowing the low densities build up. I don't care what anyone says, "LIFE _DOES_ EXIST BELOW ZONE IV". And I want it! What is your experience? It will be a PITA to retest all my film/dev combos again but it will be well worth it not to have to deal with loading those d@mned plastic reels ever again.
