...so THE question is which developer + film combination to use. I'd like firm product recommendation as opposed to this type or that type of developer....I've been told PYRO by a few people but as I said I'd like a product to get hold of.....
....also, what kit do I need to develop 5 x 4 sheets with the minimum of fuss and maximum ease.....
sorry to be so dumb but which film is TMY-2?? is it T-Max 400???
Second, I have done several tests which show conclusively that pyro staining developers like PMK and Pyrocat-HD give about a 10-15% increase in real resolution, all else being equal.
I am personally quite surprised to see someone like Lenny, who is always interested in the very best results, use methods which give less than that. The only advantage of constant agitation with a developer like Xtol used 1:1 is that the results will be very even. For acutance and resolution I would advise other methods for someone trying to get the most of film.

Well, I am all ears. Truth is, something happened. Something that really threw me. I got a series of very bad results. Especially with film that you like. I am sure it was an error of mine, but it's beyond me... could have been developer exhaustion issues. At the moment I am getting some good results from the JOBO and as soon as I get that the way I want I will try and improve to whatever method you want to suggest. A 10-15% increase sounds like a very valuable way to go. I'll add the Jobo has been fun as I don't have to be in the dark the entire time... but you're right - I'll do anything to get the results... and the consistency.
Lenny
The second issue is agitation. You can develop film in open-ended PVC tubes which you then plop into a film drum, say an old Beseler or Unicolor film drum. I can develop 8-10 sheets of 4X5 film, or 5 sheets of 5X7 film, at at time with this type of development. Once the film is in the film drum you put the top on and the rest of the development can be done in room light until it is time for the stop bath. I then just plop the tubes into a large tray containing the stop bath, at which point you can turn the lights on and fix in room light.
The advantage of this system over Jobo is that it allows one to let the film rest for local exhaustion to enhance adjacency effects and micro-contrast. I generally agitate four or five times during development, at about equal period in between.

I'm not much interested in anything but 8x10 these days. I have gotten some great results lately and don't want to go back. I am using a 3005 drum, which holds 5 8x10's. I would imagine I could load it up, then open the top in the dark and pour in chemicals, as if it were tubes, then close the top... (I could put it on the motor for stop and fix..) do you think this would work?
2) Are you saying you only agitate every two mins or so? How long are your dev times..
Might be easier to go over this offline...

I would recommend just continuing the tests with the staining developers in your Jobo as you are already familar with it. Try Pyro Max and Pyrocat-MC instead of PMK and Pyrocat-HD.
If you find that you like one or the other more than Xtol we can then talk about methods of reduced agitation to enhance micro-contrast But you should see an increase in resolution even with Jobo processing.
Sandy
I need to get this stable. As soon as I do I will add the Pyro variants back in... As I said, something very weird happened with PMK in the Jobo with 4x5 that made it look like it didn't have the power to develop a TGrained film. (Note: I caution folks here - this is a problem that occurred, you are not to take what happened as any kind of fact. It could have been something else entirely. It's just a result, not a conclusion. I like PMK...)
As you know I've been doing this for a while so I am good at mixing things, being accurate with volumes, temperature, etc. I eventually went back to D23 and got my first excellent results with that and Efke 25. I could feel the warmth of the afternoon sunlight on the rocks. Then I branched out to Xtol. I didn't think it would work, as Phenidone coats the edges of the grains with black and I didn't think it would be very good - a sort of chemical unsharp masking. Rodinal seems to do little for drum scanning, to be kind. However, Xtol surprised me... at least at 1:1.
I need to finish the choice of film I am going to use. If the Delta will stabilize and get predictable, that would be good. I would rather not pay $5 a sheet for TMax. (It's obscene how Kodak's army of bean-counters treats us.) If the Tmax is really the best, then I'll use it. The Efke 25 has held its own in every test so far. Of course, very low ISO is not the most fun thing, especially when it isn't bright out...
Another couple of weeks and I'll be back to trying some Max or MC... I might even do a little standing...
Thanks.

Are you testing Fuji Acros? If not, you might want to consider it. It has grain and resolution about like Tmax-100, but even less reciprocity failure.
Sandy
I have. We have some other criteria in our choice. We try and imagine how long it will be around. This is one of the reasons we are trying to get Delta to work, we think it will be around longer than the rest... then perhaps Krapdak, then Fuji. Efke - who knows... as for the rest, I'd rather work with a film made by a company that actually has a film manufacture line, rather than one that just buys it elsewhere...
Of course, it's mostly conjecture at this point...
Lenny
I can not imagine that the science for figuring out which film will be around the longest is very good.

Hi i'm looking into this quite a lot lately and have been looking around and just wanted to know if you would recommend this way and how you found it using the 3005 drum??
Thanks in Advance
Hi
I certainly haven't done exhaustive testing, but pyro stains may be scanner dependent (I normally use the green channel if the software doesn't pick that). I quite liked what it did when I was printing on an enlarger.
When I run out of (or perhaps just before I run out of) my current batch of D-76.
