    Re: Cambo SC v SCX

    Fred Picker (who made and sold the Zone VI folding field cameras) advocated for practicing your setup procedures a hundred? times without actually making a picture. So when you had to move fast you'd...
  2. Re: TF-4 User For Years...Want To Try TF-5

    i've been using TF-5 for film and paper for a while now. It works very well, doesn't stink, and my FP4+ negatives developed in Pyrocat have a definite "imagewise" stain. I also use a citric acid stop...
  3. Re: Schneider Goerz Red Dot Artar Lens History?

    Here's how I understand it; Schneider purchased the Goerz name in the early 1970s. They kept the Artar lenses and discontinued their (very similar) Repro-Claron line. They also made various Dagors in...
  4. Re: Any advice on cutting your own museum glass?

    I've long used acrylic for glazing, for the obvious reasons; the weight and fragility of glass. There are several museum-quality, UV-protectant types.

    I've seen this. Probably due to a slow wi-fi; it doesn't happen when I am physically close to the router. My antique MacBook probably doesn't help, either.

    If you want to shoot subjects directly overhead, perhaps a 45-degree prism might answer.

  11. Re: Carl Zeiss Tessar 18cm f/4.5 - Filter Size?

    Many, if not most, older LF lenses do not have their lens barrels made to fit the modern filter sizes. The threads on the inside of the barrel are only there to assemble the lens.

    A long time ago (late 1980s) we had a D3 at work, along with several other types of Omegas. We were able to use the D3 with a medium length cone and a 135mm lens to enlarge 4x5 negatives. I do recall...

    Re: Question using Goerz 19" Artar lens

    If nothing else, a 19" lens has little inherent depth-of-field. So you'll likely need a smaller aperture than with a shorter f.l. lens.

    It's worth mentioning that Rodinal was never meant to be used with fast films. In fact when it was introduced (in the 1890s?) there was no such thing as "fast film" and enlarging was a rarity. So it...

    Goers Artars are very sharp lenses with slightly lower contrast than lenses made in the last 40 years. They cover about 45 degrees- so this lens will work well on 4x5, might cover 5x7. A Packard...

    Re: 300mm Rodagon with Slight Edge Fungus

    You won't be using the lens wide open, I imagine. So the fungus around the edge should have no visible effect. The scratch? In such a no-flare situation I think you'd never see any evidence of it.
