    Re: ? use of Oscilloscope lenses in LF?

    Dan was more correct than he realized in commenting that these lenses are "poisoned." I was given one and happened to measure it with a Berkeley Nucleonics rad meter, a fairly good one. The...

    Re: t-max 100 alternative

    Oh, thatʻs right. Forest fires - probably the functional equivalent of vog. I photograph in Kona and Kohala, but am leaving all the lava shots to others. Thatʻs become such a cliché. And yes, this...

    Re: t-max 100 alternative

    I might give FP4+ a go if it is a bit tougher, as you say. I can still buy it here in Honolulu at Treehouse Photo. Perhaps the interaction with high humidity will be different - wonʻt know until I...

    Re: t-max 100 alternative

    Processing 8X10 on the road - Iʻm impressed. I schlep the film to and from and then of course worry about those airport X-ray machines being out of spec.

    Re: t-max 100 alternative

    I migrated from T-Max 100 to Delta 100 about 8 months ago and discovered that I had to shift the ISO to 50 from 100. Also, in Pyrocat HD, the dilution of parts A & B had to shift from 1:20 to 1:40...

    Re: Pyrocat HD source?

    Speaking of Sandy King, I have been using one of his suggested Pyrocat HD workflows in which film is processed sequentially in parts A and B, which are not mixed. Works pretty well in a JOBO.

    I scan 4X5 at 6400 on my V700 (in Scan Science oil on a Better Scanning holder), but then choose 2 as the TIFF file size reduction in Vuescan Output. The resulting file is 3200 dpi. I could probably...

  17. Re: Mounting / Framing / Exhibition & Presentation

    Sanding the gator had not occurred to me. Duhh - one of those no-brainer things. Thanks for the suggestion, Drew. As for the archival issue, it probably makes more sense to worry about the adhesive...
  18. Re: Mounting / Framing / Exhibition & Presentation

    Many thanks for the links, Bob. Iʻll be following them. I like that sprayer idea. Do you use yours with any success prior to mounting prints on gator?

    mounting, display and presentation area?

    Not specifically large format but it would still be helpful to have an area for issues related to putting up images on a wall: mounting, display and presentation. Just a thought.

    Wonderful exhibit, Kirk. I especially appreciated viewing the prints from the megaliths series. Sorry I missed you when I stopped by on 2/23.

    The Caponigro exhibit is one I definitely want to see - Iʻm delighted the work will be up while I am there, and wish I could be at the opening ... were it not for my own.

    Re: horseman VH-R question

    Sorry - wasn't aware you wanted to fold the lens into the camera body. I keep my 150 there and mount the 65 when necessary. Even my 47 is on a flat board. Good luck with the recessed board search.
