  1. Re: Diffraction. When does it really matter with LF?

    And all of this assumes a lens with a very, very flat field, something not really suitable for general photography. Dagors, for example, were kown for having a "doughnut-shaped" field if not...

    I saw this in the terrible video. Doing things this way is probably an indicator of what went wrong with the whole operation. The Deardorff men were real craftsmen who prided themselves on their...

    Re: Tennessee Deardorff Video

    I used Deardorffs for several years, first an old NFS V8 that I bought as a basket case for $400 in the early 80s and completely rebuilt with new bellows from Western Bellows. I built a backboard to...

    Re: New HC110 Liquid Same as Old HC110 Syrup?

    I switched from HC110 which I had used since the late 60s to Ilford IlfoTec HC several years ago. I found the times at 1:31 and other dilutions were exactly the same as those I had derived for HC110.

    Three corners are quite easy to drill and tap for. The fourth corner has the lock mechanism for the revolving back and the screw has to be spaced so as not to interfere. I'm not sure exactly where...
