  2. Re: Rodenstock Imagon 22cm/4 Kunstler Portratobjektiv

    Dr. Heinrich Kühn invented the concept of the Imagon. Dr. Franz Staeble was the lens designer. "Kunstler Portratobjektiv" would mean Art Portrait Lens.

    Won't the GG be allowed to fall forward to the position where the Fresnel is presently? And be a few mm closer to the lens position? Or is the lens held in position even if the space the present...
  7. Re: Fresnel screen focus distance is different from ground glass

    In any case after you have made your modifications check for sure with real film.
  8. Re: Fresnel screen focus distance is different from ground glass

    I suggest you arrange a yard stick or metre stick up on a 45 degree angle fairly close to your camera and at a wide open f stop focus first one option and then the other. Develop and see your...

    So, I note, in fairness, Adobe has returned service to Venezuela, after making a deal with the US government.

  12. Re: Adobe is going to only sell subscription based Photoshop

    I think the issue is that there is an issue with the availability of a de facto world wide resource for photography being dependant on one countries political/judicial system.

    Except Schrödinger' cat, whether alive or dead when he proposed the experiment, is absolutely certainly dead now, as cats don't live 84 years.

    Re: Aspect ratio of 10x8 and 5x4?

    How does one know the height of the film or paper until after you take the picture in portrait or landscape view? wouldn't a box of unexposed film have a mixture of 8x10 and 10x8.

  21. Re: Greta Thunberg wet plate photos by Shane Balkowitsch

    looking at the image of the image in colour, I am wondering if the scan of the wet plate wasn't lightened in reproduction.
  22. Re: Greta Thunberg wet plate photos by Shane Balkowitsch

    I can see what willie means. the flattened face has few shadows and lacks 3 dimensionality. It's possible that a bit more (or less?) exposure, that is a bit darker, might have more shadows on the...

    Re: Ilford multigrade contrast differences?

    Yes fibre glossy comes out quite nicely if you do not ferrotype it.
    And I use these and also think the RC is more contrasty, but then it's glossy. It is also a different speed.

    Threaded holes work well for me, with the added security of a nut screwed on from behind if the length of the bolt allows.

  36. Re: Video of Ansel Adams' Story of Visualization Breakthrough

    It just seems a bit precious to claim an epiphany if you already know about it and have done it. Maybe more of a development than a moment of sudden revelation.
    But I am just being cynical.
