  1. Re: Push/Pull processing if Scanning Negative

    The name of the game is basically to get sufficient shadow detail and highlight detail, along with contrast index, onto the film so that you can print it relatively easily. By "print" I mean by...

    Re: Uncertainty vs. Failure

    The way I learned to nail my exposures was to refuse to bracket. Did that scare the crap out of me? Yes, it did. But it also improved my exposures quite a bit. Better than I usually got from either...
  3. Re: Schneider Super-Symmar XL 110mm f5.6 v. Nikon Nikkor-SW 120mm f8

    My sample is perhaps the sharpest lens I've used. The nearest challenger for that "title" would be it's 80mm SSXL little brother.

    This lens is very sharp. If you're looking for a portrait lens,...
  4. Re: Issue with Jobo Process operation

    Yup. I never saw that instruction either, but it never occurred to me to use the lift any other way. Part of the problem of being a mechanical engineer I suppose. I put a 3010 drum on the processor...

    Learn to read. I didn't say a thing about magnification being equal. I said "for a given camera position and subject position". If camera position is the same, and subject position is the same,...

    Re: Technique for increasing depth of field

    That is perhaps the most difficult thing. Many an LFer starts out thinking that the plane of exact focus needs touch the main point of interest in the photograph. But if you make enough photographs...

    Re: Technique for increasing depth of field

    There are limited controls available for controlling DOF. View cameras have one that smaller formats lack, and that is camera movements.

    My experience is not everyone's experience; my work isn't...

    Kodak put in a lot of work over the decades to stabilize the latent image and increase the time it would stay usable between exposure and processing. I'm fairly sure that TMY is better at this than...

    Re: Reciprocity - how far?

    What low intensity reciprocity failure (LIRF) is about is the film not capturing enough photons to create a latent image. No latent image == nothing for the developer to develop.

    The process of...

    This would be my bet also. Especially with film hangers.
  12. Re: Is it possible/practical to make digital negative for use in an enlarger?

    I agree that halftone won't cut it, even at the highest level. That's just not what halftone is for. OTOH, some imagesetters can do continuous tone as well has halftone. I'm talking about the...

    Yes, this! We were typing at the same time, but you said it better than I did.
  14. Re: Is it possible/practical to make digital negative for use in an enlarger?

    It's not all that bad. A continuous tone imagesetter negative seems to cost about the same as drum scanning a similar negative. Maybe less; I'm comparing back and forth between NA and Europe.

  15. Re: Is it possible/practical to make digital negative for use in an enlarger?

    Yup.

  16. Re: Guaranteed-Income Program for New York Artists!

    From hammers and chisels, to brushes and easels, to cameras and darkrooms, it takes stuff to be an artist, and the artist needs a permanent place to keep and use his stuff. If they can't have that,...
  17. Re: Scheimpflug, Swing, & Architectural Photography

    Why do you think the plane of sharpest focus (that I call the plane of exact focus) should be there? It certainly doesn't have to be. And forcing that might compromise your composition.

    I'm just...

  25. Re: Should Kodak/Fuji rethink color sheet film for room temp processing?

    There hasn't been any R&D done in film, chemical processing, or darkroom printing in decades. I don't think you're going to see any now. Especially not from Kodak, which isn't really in the business...

    Re: B&W nature/landscape photography books

    The B&W landscape book for me is Adams' Yosemite and the Range of Light. It's the book that got me into this LF mess in the first place. Second place for me is probably Sexton's Quiet Light.

  29. Re: New here, new to LF, strongly considering a Wista

    One of the most striking (to me) differences between LF and smaller formats is that in smaller formats the lens plane and the film plane are rigidly connected and held parallel. This frees up a bunch...

    Re: Strange black blur spots on 4x5 320 Trix

    Dark spots on a positive (print) are caused by light spots on the negative. This usually indicates a lack of exposure. And this usually indicates dust blocking the light from the lens. If the spots...
