  1. Re: Followup On Processing Very Old (1961) Film

    Addendum: Upon inspecting some of the unexposed sheets, I see that the non-emulsion side shows blotchy discoloration and at least one of the emulsion sides shows an imperfection. This isn't...
  2. Re: Followup On Processing Very Old (1961) Film

    So far at least, I've not seen that. The trick to avoiding reticulation appears to be to keep temperatures consistent from bath to bath to wash to avoid thermally shocking the film.
  3. Re: Followup On Processing Very Old (1961) Film

    That's really cool.

    I am aware of the various "old film tricks" like using Potassium Bromide. I am specifically looking at low agitation as a technique for bringing old film to its full...
  4. Followup On Processing Very Old (1961) Film

    I finally got around to making some test prints from the negatives I made from Super-XX that had expired in January of 1961.

    I also do initially agitate 2 minutes after 3 minutes of presoak for much the reasons you mention.

    I have done semistand very successfully with Efke PL100 which is an "old school" type emulsion.

    Please go back and reread my comments. I have never had a problem with EMA. The thing I am documenting here is semistand and only old Plus-X has shown a problem with bromide drag.

    The process is great fun, but there are pragmatic reasons to pursue old film development. Among them:

    It began with the exploration of Pyrocat-HD.

    Pyrocat-HD became the gateway drug to explore low agitation development.

    That became a gateway drug for exploring the use of severely out of date...

    Actually. those were semistand developed with minimal agitation. The light edges are from not burning sufficiently on the light source side of the image.

  14. Re: High SBR: Comparing D-23 1:1 vs. Pyrocat-HD EMA

    Yes, I will either have to make do with taping them together (using the punch to re-register) or trying to find a frame. I'm fairly handy and I have access to people who like 3d printing, so making...
  15. Re: High SBR: Comparing D-23 1:1 vs. Pyrocat-HD EMA

    I cannot speak for Steve, but I'd take two approaches to this and compare the results.

    First, I'd try conventional expanded (N+) development with normal agitation using Pyrocat-HD, HC-110B,...

  18. Re: High SBR: Comparing D-23 1:1 vs. Pyrocat-HD EMA

    I've not tried it either, but I am led to believe the adjacency effects of low agitation development provide much the same results.
  19. Re: High SBR: Comparing D-23 1:1 vs. Pyrocat-HD EMA

    In principle, I agree with you. The problem is that if you are doing split VC printing for selective local contrast control by split dodge/burns, there are some images where being able to control a...
  20. Re: High SBR: Comparing D-23 1:1 vs. Pyrocat-HD EMA

    There is no such thing as a "right" workflow. Each of us works in our own way and get desired outcomes. I think its more important that we each find a workflow that is consistent and repeatably...

    Well, Plus-X isn't available in 4x5 anyway, anymore ... except for the 100 sheets I have frozen. :)

    I think these other films would show similar results. I've done a fair bit of low agitation...
  22. Re: High SBR: Comparing D-23 1:1 vs. Pyrocat-HD EMA

    Great observations Steve. I am well aware that film can hold 14-ish stops of light - I've done it myself. It is my philosophy to try and get as much onto the negative as I can and only later - in...
