  1. Re: Where are the great shots? Am I a cynicist or a realist?

    I recognize your thoughts. Your words are like mine, but still I cannot truly feel the distress - only tangentially recognize depression which I've battled all my life. Wishing you well.

  3. Re: How should I determine lens aperture corrections for tested shutter speed varianc

    Ah, of course using reversal film is critical. I did not consider that because I never use it. My lack of insight.

    To everyone - what Dan wrote.
  4. Re: How should I determine lens aperture corrections for tested shutter speed varianc

    OP - you have had all the responses necessary. My little advise: ignore those who fall into insignificant, minuscule metrics. An exposure difference of 1/3rd is entirely insignificant. In fact an...

    Re: Petzval? Really?

    Thanks, all. Your input has been helpful.

    Is it correct to presume Voightlander Euryscopes are not Petzvals. What are they?

    Petzval. I'm confused.

    Steve K nailed it. Another possibility is to find a cardboard cover that goes over the GG while its edges lay on the edge of the back. Office supply paper boxes are a source. Or spend money to get a...

    Re: Center ND filter?

    Nothing hard to understand, but let me ask what is really the typical nominal 17cm dimension for our backs, and especially roll film holders? (I would measure but I do not have any.)

    Re: External star aperture lens

    I cannot tell if you are talking to me. The filter is just one of a set of clear, yellow and red. I might still have another.

  11. Re: Okay aerial guru's: question about film size, focal length, and the jitters

    Some aerial photos were made hand-held. Surf and ye shall see. Keep in mind that expectations of image quality with non-stabilized hand-helds were low compared to today.

    Re: External star aperture lens

    I'm sorry this picture is not as clear as it could be.
    The rectangle in the center is a reflection, not part of the filter.

    Anyway, the star pattern is a center-filter. It mitigates darkening by...
  13. Re: Adjusting Clarity of Scanned Glass Plate Negatives

  18. Re: Chamonix 45N-2 - Shortest focal length lens

    When you get the camera you can measure the minimum flange focal distance which I think is just about 55mm. Then with the proper measure you can know.

    Harden. I'm not sure what it means. Does it apply to the whole emulsion, or does it vary with density caused by greater exposure? Thanks for any insight.

    Your first LF lens could very well become your last, the best. Whatever you choose use it a lot. The differences between modern lenses are not enough to worry about.
