    Re: 510 Pyro 1 Hour Stand

    I do have to try this sometime!

    I was a bit surprised about no additional agitation - like at the halfway point for example, and this makes me wonder about images with broad areas (like skies or foggy seas) of little detail and equal tones...how these might stand up to relatively big enlargements.

    Also wondering (thinking about bromide drag) if it may make a difference which film areas are placed on top in the (vertically oriented) tank, which if important would have further implications relative to vertical vs horizontal images. I would think that in the "broad skies and foggy seas" examples, especially with some moderately contrasty foreground detail, such orientation could make a real difference. Could anyone chime in on this? Steve Sherman...you around?

    FWIW, I've used 510 pyro off-and-on for many years and recently tried processing 120 roll film using the Rudiger Hartung semi-stand method as championed by Zone Imaging Lab (UK). I'll be kind and say the results were not good.

    I've yet to discover a "stand" development option that did not result in blotchy, uneven densities and/or bromide drag and hotspots at the bottom of the tank. Although the negative Martin got from 510 Pyro/Stand looked very good, I'm still skeptical that most practitioners would reliably have the same results. I suspect he'd have gotten a nearly identical negative if he'd processed the film as prescribed for 510 Pyro.

    I wish that when people did this kind of a test to demonstrate a process for the public, that they'd do a control study, comparing a control (processed normally) with the test subject. Its not very meaningful to just hold up a sheet of film and say "this is superior" unless you have a control to compare it to.

    Wasn't that written by Tammy Wynette? (hmmm...maybe her husband played with matches?)

    She did not in fact stand with her man. Think she left him for another man because he was drinking too much pyro moonshine from an improperly agitated tank called a "still". .... still waitin' for it to develop .... still longer ....
