  1. Re: What are these streaks on my neg - never seen before.

    This would be my bet also. Especially with film hangers.
  2. 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...
  3. Re: Is it possible/practical to make digital negative for use in an enlarger?

    Yes, this! We were typing at the same time, but you said it better than I did.
  4. 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.

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

    Yup.



    Not really possible from an inkjet printer. Wrong tool for the job. The problem is, it's not really possible to print inkjet dots small enough to print at photographic negative...
  6. 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,...
  7. 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...

    They are out there, but they generally are not pigment ink printers. Mostly they are either UV cure or dye sublimation printers or solvent ink printers (which can be pigments). And they don't come...

    Re: High Lights scanning problem

    I studied this in a fair amount of depth about 15 years ago. What I found is that B&W negatives optimized for darkroom printing (Grade 2 paper) typically will scan just fine. But if you're never...

    There is. Dr. Oliver Sacks contributed more than a little. And more than a little to the understanding of how the brain hears and interprets music. He was also interested in amusia and it's causes. ...

    Re: Music as analogy for LF photography

    I do. But only with LF. I've never heard any music while working with smaller formats. I don't know why, but it probably has to do with how fully engaged I am with the process.

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

    Kodak, last I heard, wasn't in the film business anymore. Who owns the gigantic film coating line in Rochester these days? Anyone know? Oren?

    And why don't you think it's a supply problem? Kodak,...
  15. 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...
  16. Re: Should Kodak/Fuji rethink color sheet film for room temp processing?

    You know of a camera with a 5x4 sensor that allows separate manipulation of lens and sensor planes? Please, tell us. I would love such a camera.

    Re: dilution for highlights

    Not the same result, no. But very similar. Vaughn is right -- the dilution of the sodium sulfite will give you somewhat sharper grain, which in turn might look like slightly more grain, but is not....

    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.

  19. 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...

    There's way more to image quality than just simple resolution. But you seem to want just simple resolution. OK, but if that's all you want you're barking up the wrong tree. A cheap digicam and a good...

    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...

    Re: Reversal vs negative

    Add to the cons:

    * Very small dynamic range compared to negatives.
    * Very high Dmax which makes scanning difficult.
    * trannies may be WYSIWYG, but WYS isn't as color accurate as negative films...

    Everything in LF is a trade off. If you open up too far you have shallow DOF. If you stop down too far you soften the image through diffraction. Etc. The bottom line as you'll find eventually, is to...
