In one of his books saint Ansel had a picture of a light bulb developed in pyro developer, try to do that one on a working light bulb with Xtol
if the question is clear tonal separation in extreme lighting conditions, pyro developers will blow the socks off the stand development. In one of his books saint Ansel had a picture of a light bulb developed in pyro developer, try to do that one on a working light bulb with Xtol

Standing development is also about boosting micro contrast, and general contrast, when you're photographing low contrast scenes.
....
I got negatives that printed well on Grade 3 paper from scenes that were foggy and low contrast, as well as scenes that were fairly brightly lit in the middle of the day with normal contrast.
So, essentially this was a "push" development, however the stand development used to control or limit grain sizes? Less agitation, so finer grain? :confused: Do I understand you right for these specific images?

The negative for the picture you mention was developed in Windisch Catechol, a pyro based developer. The reducing agent in this formula is pyrocatechin, which is different from the reducer in PMK, pyrogallol. Pyrocatechin is also the reducer in Pyrocat HD
This is a minor point but it's rather confusing when someone uses the term pyro for pyrocatechin when must people will think of pyrogallol when they see pyro. Older literature is particularly bad in this respect. The accepted chemical names are catechol and pyrogallol. Pyrocatechin is a very old name and best left in the past.
As someone who only started foolin' with pyro in 2004... =) Things have changed. In my experience, I'd estimate that 90% or more of those I speak with who use "pyro" use some form of Pyrocat.... Even on the boards it seems to be far and away the most popular - and everyone seems to refer to it as "pyro".
Have you found differently?
That does it, I'm just sticking to Rodinal.... this nomenclature is too complicated for me. =)
I'll have to try that stuff some day. After all, it was good enough for Brett Weston.
I think the recent association of 'pyro' with catechol in its many guises is purely the result of Sandy King's choice of name for the groundbreaking developer he invented.
Gerald: I will henceforth excise the word 'pyrocatechin' from my vocabulary. I place that misnomer in the same class as calling a substance as alkaline as pyrogallol 'pyrogallic acid', which some vendors still do.
I would check out the book "The Darkroom Cookbook" by Steve Anchell (and by "check out," I also mean that it may be available at a library near you). There are five useful paragraphs on stand development that will do more for you than piecing together tidbits from the Internet as your first introduction to the technique. One paragraph is introductory, one is on advantages, one is on disadvantages, and two that explain the basics of how to employ the technique.
Stand development is covered in the 3rd edition, pages 39-40.Could you possibly provide a page reference (or section)? I'm interested in trying stand development but can't seem to find this passage in the book. Thanks!
