    Re: New Carleton Watkins Book

    Flooding inland was routine. My father was one of the people in charge of the Central Valley Project that put in the first flood-control/ irrigation-storage dams. But every so often, they still...

    Re: LED Light Table?

    It's obviously something being marketing for amateur MF and 35mm slide work, and not for serious LF use. What I'd do is take a shot of a very even gray surface with larger film and a long enough lens...

    Re: Best enlarging lenses

    I don't buy some of this. Some of those early Apollo moon trip shots might have been extremely historically valuable, but weren't necessarily technically ideal. It was a learning curve. Every...

    Re: LED Light Table?

    You could try reading the same spots multiple times, but by turning the color temp meter somewhat different directions in relation to that, to see if you still get anomalous readings. But all this...

    Pere - if it's not suitable for film, it's going to be less than ideal even with a digital device. The whole point is accurately balanced RGB spectral peaks. Yes, one can jump through flaming hoops...

    Re: LED Light Table?

    Color temp meters have integrating spheres, but can still be fooled off-axis. But IF those readings in your sketch are indeed accurate, it means the light pad is hopelessly uneven in terms of color...

    Re: DOF on 8x10 vs. 4x5?

    On a very cold quiet day at the National Gallery, with almost nobody else around, I spent over three hours nose-up to a Vermeer. What's amazing about his work, as well as DaVinci's to some extent, is...

  10. Re: Doran 400 CFM darkroom fan arrived with rough, uneven louvers

    I use Doran light-baffled intake vents, but feel that you get a lot more bang for the buck with a more serious fan, and using the configuration of the ductwork to stop light. That's also a better way...

    Relative to comparable ANGLE OF VIEW, lets say you do use a 240 lens at f/22 on 4x5. But to get the same angle of view on 8x10, you'd need a 480mm lens - twice the focal length. So to obtain the...

    The lesser knob is for adjusting "drag" - or friction like reddesert describes. In some tripod heads, instead of a secondary knob there's just a set screw adjustment.
