  1. Re: Thoughts About Linhof 4x5 Technikardan 45s ?

    Thanks, Arne. Sounds like a user who does general scenic work exclusively with lenses in the wide to semi-wide range could get by with just the WA bellows. Good to know!
  2. Re: Thoughts About Linhof 4x5 Technikardan 45s ?

    Arne, off the top of your head do you recall what the maximum extension is for the WA bellows? Neither the instruction manual nor the promotional brochure for the Technikardans has that...

  5. Re: Are LF accessories compatible between brands? Looking for a reducing back

    There is no standard for back size. It's conceivable that a "clone" product might fit - for example, some of the Shen-Hao camera designs mimic certain Ebony models. But you'd have to check whether...
  6. Re: Wista 45 RF... or alternative for handheld RF work at open aperture?

    The other option would be a Polaroid conversion, which depending on the model used for the conversion can offer the advantage of a combined VF/RF, so you can avoid the problem of staying in precise...

    Re: Aspect ratio of 10x8 and 5x4?

  12. Re: How to Develop Characteristic Curves in Large Format...Cheaply

    Phil Davis's BTZS book, or at least the third edition which I have, has an appendix with some guidance on using a spot meter as a makeshift densitometer.

    The OP asked about curves. From my perspective, this is the special value of a densitometer. You don't need one to figure out how to expose adequately for the shadows or how to develop to keep the...

    I have an 8x10 box camera built around the 120mm Super-Angulon. Stop way down - I'll usually work at f/45 or f/64 - and it can more or less eke out 8x10, especially if your point of focus is short...

  30. Re: Does anyone on here use a lightweight matte inkjet paper?

    Yes! I've used UPPPM as a proof paper for Epson Hot Press Natural. They're not identical in behavior, but the UPPPM gets me close enough to save a lot of testing on the more expensive paper.
