    Re: Low Agitation With Super-Dilute HC-110

    The bromides in question are not caused exclusively by the KBr in the developer as best as I can tell. There are reaction products from the silver bromides in the film itself released during...

    Low Agitation With Super-Dilute HC-110

    I've updated my ongoing notes on low agitation development to reflect some testing I did with HC-110 diluted 1:128:

    Re: Developing tank advice

    Interesting. In my case, I am using pinch support at the top of the film and nothing elsewhere in 1/2 gal open rubber tanks. This seems to eliminate drag effects completely in all films (except one...

    Re: Developing tank advice

    Yes, this was my understanding as well. However, someone here suggested I try Pyrocat-M since it has no KBr to see if this reduced the propensity for drag. It did not, and I am unsurprised.

    OK so, to followup on this... Yesterday I mixed up a batch of Pyrocat-M and processed two sheets of exposed film using the Kodak frame hangers to suspend them in a 1/2 gal Kodak rubber tank.

    Ideally, if I can get one of the Pyrocat variants without KBr to work to suit, I can hopefully go back to standard hangar frames. These protect the film from scratching and abrasion better than...

    Yes, that does seem reasonable. The worst bromide drag I ever saw was with Semistand development of very old Plus-X sheet film from the 1970s. This disappeared entirely when I used D-23 instead...

    Re: Old Glass, New Fun

    Another cause of streaking can be static electric illumination when tearing the retention tape that secures the film to the backing paper or spool. Mostly noted in winter when things are very dry.
