    Lensboard for Linhof Color

    I just bought this camera (the original Color not the Kardan Color) cheaply, basically for its rotating back which I can adapt. That said the camera is described as being in working order and the...
  5. Re: Likely Very Naive Question, sheet film then scan to produce a digital print.

    If for no other reason, for the sheer delight of using very old lenses as they were designed to be used - to throw a very large image. This is not reproducible using any digital system as yet. Having...

    Re: What is the purpose of this baffle?

    If there was any fitment in the back (which there isn't, nor any sign of one) and if the baffle was fitted vertically, stereo might make sense. As it is I can't see how it could have any stereo...
