  2. 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,...
  3. 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...
  4. 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.

  7. 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...

    In your post #17 above, in response to Bernice Loui's question "Why view camera sheet film, Why 8x10?" you responded: resolution. Without quotes. So I took you at your word.

    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...

    Accuracy and precision are two different concepts -- they are not synonyms for each other. First thing you have to do in any discussion is to agree how to define your terms. Otherwise, your...

    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...

    Many people making the transition from small formats to larger formats feel like this. But the science doesn't back them up. Exposure is exposure and is not format dependent.

  21. Re: Diffraction. When does it really matter with LF?

    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...

    Re: Water seal for jobo 3010

    Re: Tri-X Reciprocity Failure

    Yes. But it doesn't matter that much since you typically can't use those shutter speeds much anyway. In the decade I kept track of such things I only used a 1/125 speed once or twice. Nothing faster....

    I recommend that your first lens be a 150mm, a "normal" lens. Yes, yes, yes, I know you didn't even own such a lens in 135 format. But this isn't 135 format. With LF you have separated the film plane...
