  1. Re: Question about film development and contrast

    All this is saying is "expose for the shadows and develop for the highlights" which is about as old as photography itself. There are dozens if not hundreds of exposure and development methodologies...
  2. Re: BW Film Developers for Jobo & Film Scanning Workflow

    I'm glad it works for you. I wish it would have worked for me, but it didn't. So I lost 35 years of experience with HC-110 and started over again with XTOL. PITA, but it really wasn't that bad.
    ...
  3. Re: BW Film Developers for Jobo & Film Scanning Workflow

    Short answer: XTOL or clone. HC-110 is too active to easily control with continuous agitation.

    Longer answer: It's not so much the developer. The point of any film workflow is minimizing the...

  6. Re: Challenges with Highlights in Scanning Process?

    In my experience Kodak did not lie, nor did they exaggerate. The easiest to scan films for me turned out to be the two Tmax films, and the two Portra films. I never got to scan any Ektar, but have no...
  7. Re: Challenges with Highlights in Scanning Process?

    When you say "highlights" are you referring to the negative or to the final print? IOW, are we talking about high density on the negative or low density? Just need some context here or people will be...
  8. Re: Sustainability of 8x10 film given the pricing situation

    The price of film / processing was never the limiter for me. What was, was the cost of travel. Airline tix, car rentals, meals, hotels, all completely dwarfed the cost of film and processing.

  10. Re: Where can I find "regular" LED lights with a CRI 95>?

    You could try YujiLEDs, a Chinese / German company with very high CRIs. A lot of their stuff seems to be rated at CRI of 98 or so. There's a fair amount of activity in video circles of people using...

    Re: Kodak Tri x 320 What is your opinion ?

    It *is* an old favorite. No question. It took me years to let Tri-X go. But I did. I replaced it with TMY. For a couple of reasons.

    First, TMY has much better reciprocity characteristics than any...
  12. Re: Wind movement in scenes especially with large format photography

    It is not really necessary. Photography isn't really necessary. Art isn't really necessary. People do it, or don't do it, because that's what they want. Other peoples' choices are not under our...

    Nope -- I have no experience with Imacon.
  14. Re: Are slower films more contrasty or less contrasty than faster ASA films ?

    It's a really complex system -- it is very unlikely that any posting in a forum like this will advance your understanding much. Just not enough space, or enough time.

  18. Re: A good book on LF exposure, reciprocity and bellows extension exposure compensati

    I've read a lot of photography books over the years, and never found one that treated reciprocity failure in what I'd call a good way. Probably because it's more of an exposure issue than anything...

    Re: Blowing and agitating whites

    Exactly this.

    Or as people have been saying for about as long photography has existed, "expose for the shadows, develop for the highlights".
  20. Re: Push/Pull processing if Scanning Negative

    Almost certainly not. This is more or less the way the scanner/software is designed to be used.

    If you have a sheet of film that you can easily print in the darkroom, it's usually easy to scan...
  21. Re: Push/Pull processing if Scanning Negative

    Most consumer and prosumer flatbed scanners can't read the extreme density end of color positive films. It's difficult to do with flatbeds in general because of light scattering from adjacent pixels...
  22. 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...

    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...
  24. 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,...
  25. 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...

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

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

    This would be my bet also. Especially with film hangers.
  33. 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.
  35. 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.

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

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

  38. 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.
