Anybody familiar with this?
It somehow ressembles what is called "development by inspection"
Didn't post this in the other Robert Adams thread, as it is film-development specific.
There's a passage regarding film development in American Silence: The Photographs of Robert Adams that piqued my curiosity. Talking about his apprenticeship with Myron Wood, a student of Edward Weston, the book states: "[Wood] helped Adams with his technique, showing him how to not only evaluate a contact sheet but also master a complicated method for developing negatives that produced smooth skies and delicately articulated clouds." That passage leads to the following footnote: "Adams described Woods method of developing negatives, which involved joining the ends of the film together and lifting it in and out of the developing solution... He noted that by developing his negatives this way, instead of in a tank, he no longer had streaked or mottled skies."
Anybody familiar with this? It somehow ressembles what is called "development by inspection", but I'm not sure if that's actually the case, might be something completely different. I don't know if Adams continued to used that method throughout his career, and couldn't find online the original interview in which he talks about it (Landscape magazine, 1980)
Could be a variant of the method described in this page:
The roll of film was placed in the dish while keeping hold of one end, the film could then be alternately raised and lowered for agitation. No weight was fixed to the lower end of the film, the natural curl of the film caused it to roll-up when lowered into the dish.
There was a similar two dish developing method for the old Meritol two bath developer. A picture is available on the photo memorabilia site if my memory serves me right.
Agitation becomes very important

That passage leads to the following footnote: "
Hiroshi Sugimoto has also talked about these challenges when developing the negatives from his “Seascapes” series.
I recently stumbled upon this video in which he discusses it. Looks like his solution was rotary processing using a Jobo processor.
If you have an interest in an even tonal representation of the sky, you are probably aware of the challenges one faces during development.In what way? Can you expand on this?

Sugimoto has mentioned it several times in Japanese interviews (where the subject of process and equipment talk is not as stigmatised as it appears among art photographers in the West).
The only English mention I know of, is linked above by Logan2z.
A successful agitation system in deep-tank film processes must cause the solution to move uniformly at a desired energy level and must adequately and uniformly supply fresh solution to the emulsion surface. A theoretical and practical investigation of a film strand moving through a processing solution has shown that the boundary layer between film and solution is laminar for all practical processing speeds. Laboratory tests have indicated that density nonuniformity caused by poor or insufficient agitation can be improved by the proper use of submerged nozzles. This work was made possible by a technique developed in the Kodak Research Laboratories, in which the by-products of development can be observed as they are formed. Hydroquinone sulfonate, a principal by-product of development, fluoresces when excited by ultraviolet light, producing a fluorescent layer of material on the emulsion surface, which visually shows the effect of any disturbance caused by the agitation mechanism.

I still need to pick up a copy of American Silence.
It sounds like Adams used a standard professional lab deep tank probably full of D-76 and instead of having the film on a spiral he joined the ends together. I think the reference to a 'tank' is confusion about a developing tank like a Paterson tank.
So AA joined the 2 ends of the MF film together and lifted it in and out of the developer according to the #1 but your interpretation of this is that the film is placed in a deep tank. In that tank what form does the "in and out" bit takes place and what is the frequency of this?
I develop my MF in a reel and tank system and have never noticed the mottling of skies. Have I been lucky or have I not been critical enough about mottling?
Thanks
