  1. Re: Change of density at film hanging clips on dip-dunk processing

    Just got a photo of the racks from the lab. They hold 10 sheets.

    36-40" tall stainless hangars.
  4. Re: Change of density at film hanging clips on dip-dunk processing

    Thank you for the compliment. I'll add that the nitrogen-burst agitation in these 40-inch deep tanks is pretty aggressive at 8 second burst then 8 seconds pause. I did a lot of tests after having...
  5. Re: Change of density at film hanging clips on dip-dunk processing

    I was thinking it might be a chemical crossover from the previous run, but since the result was mostly added density and not reduced density I couldn't see how that would happen. The rack (holds 8...
  6. Change of density at film hanging clips on dip-dunk processing

    Re: Push/Pull processing if Scanning Negative

    I feel you. But it would be honest to say that after initial contact printing, most of the film transmitted to HDP since 1990 will never, ever see the light of an enlarger lamp house... so it is...

  10. Re: Toyo 125VX Tripod foot clamp and quick release

    Ah, thanks Sergey, I have a few Geared heads with an Arca QR and a Manfrotto 405 (and a 410) with their respective plates, so I have the ability to add the ARCA or 405 plate to the bottom of the base...
  11. Re: Toyo 125VX Tripod foot clamp and quick release

    Thanks Sergey, Yes, I saw that quick release, but look at the photos. it just screws to the bottom like any normal release, it doesn’t use the Toyo VX125 foot.

    Thanks for reminding me of my old B&H sourcebook. I saw the quick release on the stroboframe page (464) and then looked at the Gitzo page (435) and there is a Gitzo Quick release (#G385-14 and...
  13. Re: Toyo 125VX Tripod foot clamp and quick release

    Sergey, do you have one? I do not have an Arca-sized QR head that will open that far. I have several Arca type quick release accessories and they are all significantly narrower than the foot on the...
  14. Re: Toyo 125VX Tripod foot clamp and quick release

    Yep. So far as I can tell from those old manuals and brochures Toyo did have a Quick Release, but I have not been able to find any details or find a photo of one that was not in a Toyo publication. I...
  15. Toyo 125VX Tripod foot clamp and quick release

    Riddle me this... What does the foot on the bottom of the Toyo 125VX slide into? It is wider than Arca sized, and thinner than Manfrotto/ARRI cinema sized.

    The HABS/HAER/HALS website does not have a documentation of the Ford plant (yet). It is possible that it was recently documented (somehow doubt it) and the photos have not been transmitted to the NPS...
  17. Re: Schneider Super Angulon 72mm XL - filter conundrum

    I am not a physicist. In practice, I find the outer edge of the Image Circle on the 72XL grows a little when I stop down. And the filters I use at the edge of the mechanical vignette at full rise or...

  22. Re: HOW TO Load Film Holders. A tutorial video for beginners.

    That is correct. I was taught that at school too.

  34. Re: Cambo 4x5...how to know how wide you can go

    Adam, your camera has a rotating 4x5 back that adds to the distance inside the camera. If you get the non-rotating 4x5 back you'll gain a few millimeters. Bag bellows will definitely help. If you...
