    Re: Pin registration system preferences

    I'm making a light source & carrier that more closely matches my needs - I have various dislikes about the later De Vere carrier (especially the hinges) & its pin register variant is a bit improvised...

    Pin registration system preferences

    For those who use pin register systems, do you find the small pins within the film margins (Condit, Inglis) better/ more precise than bigger pins on a taped on strip (Radeka, Durst)? I'm in the...
  3. Re: The Camera and Technique of Andreas Gursky (Then And Now)

    And I've made lots of scans and inkjet/ darkroom prints from multiple source materials in all the main formats, seen innumerable different scans & darkroom prints & the Kodak research holds up in my...
  4. Re: The Camera and Technique of Andreas Gursky (Then And Now)

    This isn't the case either in theory or practice. Neg-pos always beats pos-pos quite definitively in granularity and sharpness. It's why cinema uses/ used a neg/ pos process - there is a large amount...

    Re: calling all Durst 184 Laborators

    Been hunting for that document for months - thanks!

    I'm slightly surprised that the 135 & 120 WA apparently cover 5x7 out to 2-2.5x, but otherwise there's nothing totally unexpected there.

    Re: calling all Durst 184 Laborators

    Does it really cover 8x10 at 5x?

    Re: The new Tri-X 8x10 film

    It was the move to Building 38's coating machine, and was around 2005. 2007 was when Tmax 400's revision into TMY-II happened.

    Re: The new Tri-X 8x10 film

    Not correct, on the basis of the best available information.

    It does use aspects of sensitising & layered dye technology in common with the tabular films & that is a likely cause of confusion -...

    Re: Unsharp Masks - When Not Worth the Effort

    Xtol is not designed to be ultra low fog. None of the modern high speed, high sharpness & fine grain developers are designed to be. At best, once you add the Rodinal, you are probably ending up with...

    Re: Unsharp Masks - When Not Worth the Effort

    This is not correct, what the mask is doing is raising the density of the original negative's shadows, hopefully without affecting the highlights (which is the point of the restrainer when processing...

    Re: Unsharp Masks - When Not Worth the Effort

    Pere - I think what Drew is getting at is that you want to minimise the mask's impact on the original negative's highlights (hence the restrainer) but don't want to make the mask too dense either,...

    Re: Devere 515 lift pins

    Bob Carnie has one & should probably be able to tell you the dimensions. If not, John Boyce of Odyssey Sales/ De Vere can almost certainly tell you.
  16. Re: I take back every bad word I have said about Kodak...

    For example ADOX's MCC/MCP uses 4 emulsion components, new Polywarmtone also has 4 & needs to be coated as a 2 emulsion layer package (+ supercoating). Old emulsions like some of the Dupont/ Efke era...

  18. Re: I take back every bad word I have said about Kodak...

    Nope: it can be as few as 2, as many as 5. May be a single layer & with the dyes heavily ballasted etc, or 2 layer coating, again with ballasts etc. Very little of each dye is used (to prevent...

    Essentially it sounds like you have discovered that there's no such thing as an unprintable density, even at the point that the curve has compressed the useful contrast to the point of no separation...
  21. Re: I take back every bad word I have said about Kodak...

    You've got this backwards. The more pronounced an S-curve's shoulder is, the more it compresses the highlights & makes it harder to burn them in while maintaining good separation. The more linear the...
  22. Re: Performance Between Apo Symmar and Apo Symmar-L?

    I recall Zeiss saying words to that effect when they redesigned the 38mm Biogon too. Though I can't remember if it was an outright ban, or that new regulations would make it uneconomic to manufacture...

  25. Re: question about using the 4x5 Epson scanner lens to scan 5.9" wide and stitch 8x10

    Whether people like it or not, it's safest to regard the best possible output from an Epson to be 1200ppi at not spectacular MTF performance. No amount of silly claims of magical sharpening routines...

    Re: Apo-Componon HM optimisation range

    The 90, 120, 150mm are the major ones of interest, however, the 40, 45 & 60 would also be handy to know. I'm mainly interested in what the specified maximum enlargement capability was.

  32. Re: Did Kodak color neg lose sharpness when it was reformulated to improve scanning?

    DP-II is used quite widely for optical printing in Europe but is often masked/ flashed. The results are excellent.

  34. Re: Did Kodak color neg lose sharpness when it was reformulated to improve scanning?

    I'd agree that masks are far superior, though it's often a question of whether a client will pay for them. This is where printing for yourself has distinct advantages as you have the freedom to...
  35. Re: Did Kodak color neg lose sharpness when it was reformulated to improve scanning?

    Drew - I'd add that a lot of professional printers in Europe are using controlled negative base tint flash/ fog to control some of the higher saturation papers.
