  1. Re: Any information on Camille Desmoulins lenses?

    Thanks! Very helpful and interesting.
  2. Re: Any information on Camille Desmoulins lenses?

    Steven, can you show us where these booklets are available? My googling goes terribly wrong when I try either Camille Desmoulins or A to Z booklets by Le Reve.

    Yes, SK Grimes etched it for me. I described what I wanted, and he did it.
  4. Re: Options for 190mm- 210mm wide lenses that cover 8x10 WIDE OPEN

    Thanks for the reference John, but nothing I looked at would cover 8x10. I was looking for much smaller coverage.

    I heard said that among lenses there are three characteristics--fast, wide,...

    Re: polyptych photos

    Rob, I am not sure, it was a few years back, but I probably composed from left to right.

    I think rear movements are probably the way to go with these. Moving the vantage point of the lens would...

    Re: polyptych photos

    That is right, I shifted the width of the image, which is a tad bit under 5". I suppose for distant images you might be able to get away with front shift or rise, but the advantage for rear shift is...

    Re: polyptych photos

    I have done this a few times with three 5x7 negatives making a 7x15" final contact print. My approach was to use rear shift rather than move the camera. This won't work with most cameras, but my 5x7...

    Re: Ken Hansen

    I bought my first new-in-the-box camera from Ken, a Leica M6, in 1991 or 1992. It was a major purchase for me, and Ken was very patient and understanding with me as my credit cards were declined, and...

    Re: Wash Aid?

    Wash aid is just sodium sulfite and sodium (meta)bisulfate. If you have those in house you can mix them yourself, otherwise you can buy a mix (like the formulary's) or just wash longer.

    Re: Lane Dry Plates

    Thanks for the suggestion, I am using Linhof plate holders. I have used these for years in 6x9, 4x5, and 13x18 with plates that are far more sensitive to scratching than dry-plates, so am pretty sure...

    In my experience, yes, the Hugo Meyer Atelier Schnellarbeiter is actually about f3.5. This is based on measurements and exposure tests which I made with one 36cm version.
  26. Re: question about mid-1850s lenses

    In the mid-1850s there wasn't much choice. He almost certainly used an achromatic landscape lens. The sample of images I see via Google do not appear to be made with a Petzval or a meniscus, which...

  34. Re: Good starter lens for whole plate

    A Fujinon-W 250/6.7 on whole plate is pretty close to "normal" with a big image circle, number 1 shutter, and not too dim.

  36. Re: Hugo meyer Atelier-Schnellarbeiter 360mm f3 petzval

  37. Re: Aero Ektar 12 inches f/2.5 with shutter on 8x10

    Is that the 13.5" f/3.5 Aero-Ektar or the 12" f/2.5? The barrel is from the f3.5 version, but I think they are the same size barrel (fits the 24" f6 version too)... just curious.

    Schneider claimed that the 10.5cm f3.5 Xenar had a 4 5/16" (~110mm) "circle of sharp definition at small stop," barely enough for 2x3, let alone 4x5.

    No, you need a Compur II shutter or Copal/Compur III with adapters.

    The 150/2.8 Xenotar lenses were originally mounted in a Compur II shutter variant (II 5/2+3). Not all Compur II shutters will...
