  1. Re: Easy fix that makes a 4x5 Gowland-Calumet Pocket View less fiddly and easier to

    I agree, if knobs were substituted for Allen hex head bolts, then the Gowland/Calumet is not fiddly. That's the point of this thread.

    Some of the Allen hex heads on my Gowland/Calumet were...
  2. Easy fix that makes a 4x5 Gowland-Calumet Pocket View less fiddly and easier to use

    While the 4x5 Gowland Pocket View ( also sold under the Calumet brand) is among the smallest and lightest 4x5 monorails of which I'm aware, my stock camera came new from Calumet with mostly...

    Re: Sturdy 4x5?

    FWIW in terms of sturdy 4x5 field cameras at a rational price, the US-made Meridian B is comparable to the MPP and some Wista field cameras. It's a solid late 1940s press camera style body, entirely...
  4. Re: 150mm lens suggestion for landscapes on a Cambo 45NX

    IMHO, at the normal working apertures for large format cameras ( usually f/22 to f/32), most modern first-tier lenses in the 150mm range from Nikon, Fujinon, Rodenstock and Schneider will be...

    Re: 12" Goerz Dagor?

    Echoing comments about constant iterations in everything but the name Dagor, my experience with Dagors has been all over the map.

    I had an old uncoated 120mm German-made Dagor that I sold, much...

    Re: Starting with ULF

    A 300mm Dagor works fine as a wide-angle on my 11x14 by f/32, as does my 305 G-Claron, as another poster has noted. The Fujinon 250mm/6.7 original W is claimed to have an 80 degree coverage and that...

    Re: Useful LED digital light table

    Both of mine have continued to work fine. At $24, it's not a major risk.

    The actual user review summary from Amazon shows 78% five stars, another 9% four stars (that totals 87% ) 6% one star,...

    Useful LED digital light table

    Light tables are really useful for viewing processed negatives under a magnifier, but traditional light tables were expensive and bulky. I recently found some A4 size 9"x12" LED "tracing tables" at...
  9. Re: Some tests rank-ordering a variety of classic and modern LF lenses

    Hi, Arne:

    Now that you mention it, I do recall seeing this very helpful set of test results some time back. My error and my apologies - I probably should have recalled it. I don't want to think...
  10. Re: Some tests rank-ordering a variety of classic and modern LF lenses

    Hi, Drew: I concur with everything you note in the above post. It's a matter of the right tool for the job. My starting point is high sharpness and good acutance in a relatively flare-free lens,...
  11. Re: Some tests rank-ordering a variety of classic and modern LF lenses

    The reason that I took my personal results and started this thread was because I have noticed over the years that there's not much in the way of even basic comparative LF lens data on the web since...
  12. Re: Some tests rank-ordering a variety of classic and modern LF lenses

    Sorry, perhaps I mis-phrased, apparently, in responding to what I thought was a question about testing for "field curvature". I used standard flat test targets and did not separately test for field...
  13. Re: Some tests rank-ordering a variety of classic and modern LF lenses

    Tested at 1:20, approximating my normal working distance and with flat field target perpendicular to lens axis. I was basically sorting out which lenses would work best for my own use and working...
  14. Re: Some tests rank-ordering a variety of classic and modern LF lenses

    I measured visually perceived acutance and resolution directly on Delta 100 5x7 negatives on a light table with a loupe. I used sufficient ISO 12233 targets (modified to include some additional...
  15. Re: Some tests rank-ordering a variety of classic and modern LF lenses

    There were only two Tessar types, the Nikkor Qs, which are older single-coated pre-M variants in a factory Copal 3 mount. They are certainly usable optics but that lower ranking surprised me as...
  16. Re: Some tests rank-ordering a variety of classic and modern LF lenses

    Not sure that I understand the abbreviation? Are you referring to variance?
  17. Some tests rank-ordering a variety of classic and modern LF lenses

    With some trepidation, given the flame-wars that seem to occur too often when discussing lenses and other photographic topics, I am posting the rank-ordered results of tests that I have made of the...
  18. Re: Epson V850 work-around for scanning 5x7 negatives.

    This thread has been an interesting discussion spanning real world results and theory. Rereading it, I have a few summary thoughts about using the V850 to scan LF film:

    1. Even with an advertised...
  19. Re: Epson V850 work-around for scanning 5x7 negatives.

    I may have not been adequately clear in my prior posting, and hence may have inadvertently caused some confusion, leading the discussion off the OP topic. My apologies. I will attempt to clarify.

  20. Re: Epson V850 work-around for scanning 5x7 negatives.

    FWIW, my comments starting this thread resulted from making nearly 150 5x7 test negatives. I tested 34 different LF lenses and chose the sharpest negative of all. In many instances, I retested some...
  21. Re: Epson V850 work-around for scanning 5x7 negatives.

    As I noted in my original post, the 2400 dpi was, for me, the best overall compromise.

    The amount of additional resolution beyond 2400 dpi is fairly minimal but the file size is much larger and...
  22. Re: Epson V850 work-around for scanning 5x7 negatives.

    Yes, I sharpened quite a bit in Lightroom as part of my calibration tests. I also used Clarity +26 slider. The raw scanner output was not as clean and sharp as one would like for an end result,...
  23. Re: Epson V850 work-around for scanning 5x7 negatives.

    A full 16 bit grey scale TIFF scan of the 5x7 negative at 2400 dpi is about 340 megabytes on disk when using both Epson Scan and VueScan. My next set of calibration scans is focused upon tonal range...
  24. Re: Strategies in Cold - During and After Shoot

    The 1999 Kodak C9 publication that Willie references is excellent. However, Kodak does recommend in that publication that sheet film cameras should be avoided wherever possible in very cold...
  25. Re: Epson V850 work-around for scanning 5x7 negatives.

    I first tried the mat board approach with corner holders but could not get a scan that was in sharp focus on the V850. That's why I hacked the dual 4x5 4990 holder into a 5x7 holder. There was...
  26. Re: Epson V850 work-around for scanning 5x7 negatives.

    I've found that anti-glare glass from a picture-framing shop also works OK if the mat side is down and in contact with the negative. It's also much less expensive. I bought commercial ANR glass for...
  27. Re: Epson V850 work-around for scanning 5x7 negatives.

    Yes, you can lay the 5x7 negatives on the scanner, emulsion side down facing the glass. Then, put Anti-Newton Ring glass on top (mat side down on to top of negative) to hold the negative flat. I...
  28. Epson V850 work-around for scanning 5x7 negatives.

    Hi, I'm new to this forum but not to large format photography, which I've done since the 1970s. Recently, I started using 5x7, mostly Ilford Delta 100 BW film in that size, but now scanned rather...
