  1. Re: Compur shutter with no threads at the back side?

    Looks like a bajonet mount.
  2. Re: I Built an 8×10 Paper Negative Box Camera… and It Works!.........not me

    If those photos are with the Fuji GX lens, then I'm surprised it covers that well.

  4. Re: How did they blacken the metal stops & caps of the Daguerre era lenses?

    Lots of options here. One from a 1936 lab manual: https://aip.scitation.org/doi/pdf/10.1063/1.1752115 Selenium dioxide is another one and you can find that around in ready-made products (poisonous!).

  8. Re: 'Journey' in trying to build a 1850 sliding box camera

    Very nice woodworking here. And doing it from recycled wood as well is an extra challenge.

    Teak was used but more for "tropical" camera's from what I remember visiting the Ernemann museum.

  10. Re: Any suggestions on who to commission to help me build a camera?

    Maybe a bit more specific about what type of camera you would like to have build? A wooden or metal camera makes a large difference I'd think.

    Re: Looking for a budget 360mm for portraits?

    Is it? When you are shooting at 10 <insert currency of your liking> for each shot then a single box of sheets rapidly approaches the price of a lens.

  14. Re: Precision and Accuracy in LF Photography: How much is enough?

    I did have the luck that someone showed me how to develop and yes, this is still the best way to learn. But there are very few clubs around and none of them have film users afaik.
  15. Re: Precision and Accuracy in LF Photography: How much is enough?

    It is a Seconik L-758D and it agrees with any digital camera I have (Canon 5DII and Mamiya ZD) and it agrees with all MF slides (Provia 400X and 100F and Velvia 100) I have taken the last 10 years....
  16. Re: Precision and Accuracy in LF Photography: How much is enough?

    Where do I start a new thread about this? I have really no idea if this is a lens, shutter, film, development or other issue.

  20. Re: Precision and Accuracy in LF Photography: How much is enough?

    Those are 4 different films, exposed to their nominal iso rating, developed according to their makers datasheet for the developer used. It was Delta 100, Fomapan 100, FP4+ and Adox CHS100II.

  22. Re: Precision and Accuracy in LF Photography: How much is enough?

    Amen. I came to the same conclusion. For some reason, LF is just a lottery.



    Which is a fallacy. There should not be any difference in lattitude compared to other formats. Any optical property...

    Indeed, a beautiful camera! Very professional finish.
  24. Re: Precision and Accuracy in LF Photography: How much is enough?

    I think another thing that is missing is repeatability. This is different from accuracy and precision.

    Has anyone thought about how much a camera changes when you use it at any other temperature...
  25. Re: Precision and Accuracy in LF Photography: How much is enough?

    Good questions for having discussions at the picolux and femtolux protection society. But just like you, I feel that some are only of concern for machinists and lab equipment.

  28. Re: Large and rather interesting Schneider Optik lens in large shroud or barrel???

    Very likely a Mamiya 645 mount. (P6 has 3 identical petals, M645 has 3 different sized ones)

    Re: Removal of graphite from aperture blades

    Looks normal to me. This type of shutter works with polarisation so you loose always about half the light. Same for Kerr cells. Might also be difficult to make it 100% opaque.
  30. Re: Large and rather interesting Schneider Optik lens in large shroud or barrel???

    My first tought was that it could be a Pentacon 6 mount. But then again, the 3 petals look a bit too large to be P6. What is the diameter of the lens mount (with and without the petals)?

    Re: Removal of graphite from aperture blades

    One day, they will be worn so far that a simple clean will not restore them. You might need to build up metal on the surface (and maybe resurface) to get within working spec.
