    Re: Should there be a Wet Plate subforum?

    One of the great problems with the Internet is the diffuse and repetitive nature of information. There seem to multiple Facebook groups on almost any topic you can imagine, photo-related or not. I...
  2. Re: Seeking Ideas For Replacing Film Holder Labels?

    Isopropanol (a.k.a. isopropyl alcohol) dissolves some inks including Sharpie and won't hurt the plastic. I'd try it before resorting to acetone or nail polish remover.
  3. Re: Pens for marking or numbering film negatives - HABS & HAER guidance 2020.

    As Schaf said, the Micron and Staedtler pigment liner pens work well for me on both 120 and LF film.

  4. Re: Chromium intensifier vs Silver intensifier

    Not long ago I found a filter that prints with even higher contrast than an Ilford #5 or a Rosco 68 - the Rosco 384. The #5 and R68 print with near-identical contrast with my Aristo V54-equipped...

    Re: Tape like a post it note

    This is what you want. It's Post-It note adhesive on a roll of tape. The box I bought said Removable Magic Tape. It comes in several widths, I bought both 1/2" and 3/4" at Dick Blick.

    Re: Ansel Adam's books...what version??

    Since you say this book is hard to find, could you summarize the "Sheet Film Attenuator"? Is it a home-made step wedge, or something more?
  10. Re: Please Help Identify "Type Y" Caltar Lens

    I believe this may be a Rodenstock Ysarex, but I don't remember where this bit of mental lint came from. The Vade-Mecum doesn't mention LF Ysarex lenses, but the Rodenstock GmbH Wikipedia page lists...

    Re: Copal 3 Shutter

    And just to make it more confusing, sometimes the 3S-sized shutters are marked as 3, or even just "Copal". You really need to measure them.

    A later 355mm G-Claron should be a direct fit to a...
  13. Re: Months-away tide prediction site or app?

    Interesting. I'll have to see if they have something similar for where I'll be in CA, though I'll have to find a station number first. Alternately, I can just use the Maine info and figure out the...

  16. Re: Special production run of extended lensboard similar to Beseler #8088

    Hi Danny,

    Yes, that was the 150mm Apo-Componon-HM f/4. I used to have one, and the special mounting board, but foolishly sold both some time ago. It was a little tricky to mount it on the...
  17. Special production run of extended lensboard similar to Beseler #8088

    The Beseler 8088 lensboard was designed specifically for the 150mm Apo-Componon-HM enlarging lens, which was difficult to place and remove on a Beseler 4x5 enlarger when mounted on a flat lensboard....

  20. Re: Has there ever been a retrofocus wide that covers 4x5/9x12 or larger?

    Following up on Corran's posts, my 75mm f/6.3 Komura has a measured-by-me flange focal distance of right around 100mm.

    I have PDFs of Nikkor brochures from 1982 and 2004, and both state the "attachment size" as 67mm. I can read part of the serial number of the lens pictured in the 1982 brochure - 741xxx, which is in...

    Mind what others have said about the #00 shutter. Its repair possibilities are very, very limited.

  28. Re: Schneider Apo-Componon HM 150 would be better suited as a landscape lens?

    If memory serves the cells of the 150mm are a direct fit to a Copal 1 shutter, although I can't find anything about this in Schneider's data sheet. I sold my copy a while ago so can't check.

    Great find! Huge coverage, I think 95 degrees at f/22. It fits a Copal 3S shutter.

  33. Re: Anyone besides Lee make a ND 0.1 filter?

    Answering my own question here - Kodak used to make ND 0.1 Wratten filters, and sealed ones are available on eBay. True, they're 3"x3" filters for $10 rather than 20"x24" filter sheets for $7, but a...
  34. Anyone besides Lee make a ND 0.1 filter?

    Bob, do you happen to know how thick that quartz window was? It might be interesting to try a piece a glass in front of the 600mm Vivitar solid cat I bought on a lark.
