"Geometry" in this context could also be said to be "topology" or shape. We've all had the situation where - even with a PyroVery interesting. Thank you.
May I make a few random comments?
I’m unfamiliar with your use of the word “geometry” in this context.
To my surprise, “Extreme” Minimum agitation has more agitation than “ordinary” minimal agitation.
It makes good sense that initial agitation reduces drag. We usually think of development as consuming the developer, but of course, it’s consuming developable silver halides too.
I have a Yankee tank. No strategy that I could devise would produce decent negatives from it.
May I suggest that there are other tanks that you might try, if you care to continue your excellent work? I’ve had decent results (by my standards) from both the 5x4 Stearman and the (now out of production) Combiplan. For your purposes, the new 10x8 Stearman tank (which I have not handled) might be ideal.
I’m dwelling on tanks here, because they make development possible without a darkroom and some photographers seem to be without one.
I don’t know if they are available outside the UK , but the vertical tanks made by Nova might prove interesting.
Thank you again.
In full disclosure, the techniques I tested could have been done with dilute HC-110 or - more commonly - Rodinal. PMK Likely would not work well. It has a high oxidation rate and really needs a lot of nearly continuous agitation, thereby exhausting pretty quickly.Thanks for that article fun of some very useful info. I have just started using Pyrocat HD after hearing much about it but before I used PMK and loved it. I always find these stained negs more of an inspiration to to try and print. I am currently only using 35mm and 120 but will certainly use your article as a guide moving forward.
Yes, split printing definitely helps, but there are some image "geometries" where nothing works well, and that's where stand techniques can help.The Yankee worked well as a clearing tank for Polaroids. Ah, those Good Old Days!
If I understand it rightly, the left hand of processing (if development is the right...) can overcome the snow on twigs problem by split-grade printing. I've not tried it, b ut I've read the claims.
It is one of the problems that can be solved more easily on screen.
