These questions are aimed at LF photographers who use pyro PMK and/or pyrocat and jobo tools.
This ended up being very long, so I’ve decided to break up my questions into two posts. First I want to decide on the processing tools and once I decide that, I will address the questions around pyro.
My background
A year and a half ago, I returned to the darkroom after a couple decades’ absence. I’m taking photo courses at a community college, so have access to a darkroom until I get something rigged up for myself at home. I process my medium format film (daylight processing) at home so that I don’t waste precious, limited darkroom time processing film at school. And I plan to do the same with the 4x5 negatives, so please don’t tell me I should process in trays, like my darkroom instructor did.
I’ve wanted to try my hand at large format for decades. I recently bought a 4x5 field camera on ebay, but haven’t taken it out for a spin yet. Before I do, I’d like to decide upon how I am going to process the film. One of my darkroom instructors suggested using Ilford FP4+ and pyro. He produces amazing prints, so I plan on giving that combination a try. I’ve been reading everything I can find about pyro(including buying and reading the book of pyro), but I still have questions. I’ve decided to try both pyro PMK and pyrocat to see which I like best. Right now, I will be printing/enlarging the negatives using non-alternative methods, but I foresee platinum/palladium /gum bichromate / who knows what else in my future.
Which way to go? I need to pick one, because I don’t have everything needed for either of the approaches yet.
Jobo 3006 and Beseler motor base and/or Jobo 1509 roller base
OR
Jobo cpe processor and 2509n
JOBO 3006 option
Seems to me that using the Jobo 3006 would be the easiest way to go at least when it comes to loading the film (although since I will be loading it in a changing bag, I will load it dry.) My concerns are pouring the chemicals and maintaining the temperature. Using a funnel with a hose seems the consensus way that people not using a CPA or CPP pour the chemicals into the tank. One person in the forum who uses an expert tank said he started off with his tank on a motor base so that the tank is rotating while he adds the chemicals, which made sense to me. He then transferred the tank to a roller base and rotated it like crazy to develop his film. The roller base looks like it’s a pretty simple tool that could be immersed in water, so I’m thinking that would be a good way to keep a constant temperature. (In the winter, I keep my house between 60 and 65 degrees, so would need a warm water bath to keep a constant 70 temperature, for example.)
Does this make sense? Any comments or questions?
JOBO 2509n option
Most days I hate loading 120 film onto the ss reel to develop the film. I have good days and bad days and the bad days stick in my mind more than the good days. The bad days are when the film is just not loading well and I have to try and try again. Interesting side note: I recently bought some equipment (sort of an estate sale) which included a couple old 120 ss reels. I find they are much easier to load than my newer ones. (I gave most of my darkroom equipment away 4 years ago. Let’s not go there) I’m afraid that I am going to encounter the same frustration with loading film onto the 2509n. I know there is a loader, but I’ve read mixed reviews about it. The good news with this approach is that I have a CPE processor with a lift (I bought an enlarger at the estate sale mentioned above through a Craigslist ad and they threw in the jobo processor and lots of other stuff.)
So, in your experience with the above tools and developing with pyro, which way would you suggest I go?
Once I decide on the approach, I’ll open another post about processing with pyro PMK and pyrocat using that approach.
Thanks for your help.
