    Re: Just 3D printed a technika board

    Good question, Peter. The short (and long) answer is that I don't know. Hygroscopicity is a known issue with Polylactic acid as is relative intolerance to extended exposure to high temperatures. (I...

    Re: Just 3D printed a technika board

    By the way I found some information that looks like the ECO-ABS starts to soften in the 60 - 65 C range so it should be OK for normal use - unless you live in Death Valley

    Re: Just 3D printed a technika board

    @ Andy

    The flange itself adds a lot of strength to the board. By the way, my next project is to print a back for my 5 X 7 Linhof Kardan Bi. I've lost track of my 5 x 7 to 4 x 5 reducing back so...

  8. Re: New Zeiss apertures to f-stop converter

    Thanks much. I've seen that one. What I'm wondering is whether anyone has mapped the number from say 27.36 to the nearest third or half stop between f/22 and f.32.

    f 27.36 isn't a particularly...

    Re: Just 3D printed a technika board

    I mostly use longish lenses so don't often need a recessed board. On the other hand maybe I need one for my 90mm Super Angulon so I can get some rise/shift - sounds like enough reason to make one:)

    Opposite problem here - the "cold" water can get up to almost 90 in the Summer. One "solution" has to been to use Ilford XP-2 in the summer since it's a c41 process. But that only works for MF:(
