  1. Re: Which lenses did Carleton Watkins use in 1861 for his mammoth plate camera

    The only mammoth plate lens Watkins is ever known to have used is the 16-inch Harrison & Schnitzer Globe Lens. Here it is on Watkins camera in Yosemite. The British patent for the Globe Lens is...
  2. Re: Help choosing a "soft focus" lens, please.

    Simple answer, the Verito. It's a true historic soft focus lens, and there are enough around that the price is pretty reasonable. And there's no denying it gives beautiful results.

    The Kodak...

    Re: Petzval vs. Projection Petzval

    Unless you've pulled it apart, I wouldn't be certain that's a Petzval. B&L made a lot of triplets that looked like that.

    Interesting. I've seen a few fakes, but never a fake CC Harrison. Still, Harrison had a stellar reputation, so it's very possible. I wonder whether it has a radial drive. (No drive visible in the...

    Re: Which lens would you choose?

    Whichever one is coated. All are Dialyts with six interior air-glass surfaces, and uncoated versions will have lots of flare. Especially bad for a landscape lens.

    The Raptar will be coated. The...
  13. Re: C.C. Harrison, and Rapid Rectilinear, and... Unknown Lenses?

    Valuations aren't allowed here, but if you're planning to use them, it's just trivia anyways. The nicest is the CC Harrison, which should cover while plate (6.5 x 8.5 inches) or maybe 8x10, and it's...
  14. Re: Questions about nominal vs. effective aperture for LF close-up work in a studio.

    A Fresnel lens might be the way to go. A condenser lens or magnifying glass may be even better options. It's going to take some experimenting. If only I had a period of time locked in my house...
  17. Re: Questions about nominal vs. effective aperture for LF close-up work in a studio.

    Just to confuse things further, "f/stop" is a ratio of f (focal length) to aperture (the "stop", like Waterhouse stops). Since the "f" (focal length) is the distance from the lens to the film (focal...

    Re: Condenser lens in a snoot?

    Even without a disk, that lens in that position will cut the light level significantly. To get the most light, you'd have to remove the lens. And then you're back to a conventional empty snoot. And...

    Condenser lens in a snoot?

    Just curious if anyone has ever heard of using a condenser lens of any sort in a snoot to increase light output in the given area? I've been searching, but can't find much.

    You're right, the thickness doesn't matter. What matters is that the ground plane is in the right place, so make sure your spare gg seats correctly. Also, if it's much thicker, be sure the clips...
