    Re: f64

    I think depth of field as an aesthetic concern always trumps resolution. If all we only cared about was resolution, we'd be stitching digital images. Whether to stop down beyond what depth of field...

    Re: f64

    I saw some very impressive 10x enlargements from 4x5 that were shot at f45. The photographer remarked that keeping everything in focus matters psychologically a lot more than having fine detail up...

    Thanks, I should have been a little clearer re: what I'm trying to accomplish, though. I've recently seen a weird amount of demand for "normal" lenses with super shallow focus for video, but no one...

    Re: 150mm Sironar S or N

    Just based on mtf charts, the N is extremely close to the S (up until the edges, where it falls off) and superior to even the Apo-Symmar-L. But different manufacturers measure mtf differently, so......

    Thanks all, this has been edifying. I take it that wind and creep during long exposures are the primary concerns with tripods for lf and so I've decided to try an Induro C214 tripod and a good...

    Thanks for the feedback. This is more about weight than cost (though, unfortunately, lightweight and sturdy is the most expensive combination, so it's about cost, too). For me, the issue with large...

    Very interesting. Are you saying there's a .25mm variation between focal plane and film plane (plus or minus whatever is introduced by the film holder) with the 45a? That's petty egregious. Is...

    For my Toyo 45aii.

  23. Re: What 8x10 lens do I need for full face portraits like this?

    300mm or 360mm sounds likely. The lens is somewhat wide for portraiture, based on the shape of the face. The lighting is pretty obvious from looking in the eyes, two huge soft lights very close to...

  25. How much should I tighten the retaining ring?

    Between the shutter and lensboard. Dumb question of the day.

    The red enhancers look pretty cool. But, in practice, are they really any better than just tinting the entire frame red? The "greenhancer" definitely just looks like a green-tinted filter.
