    Re: Help me choose a camera to hike 2000+ miles

    If all you were looking for were convenience, you could just use your phone. If you're looking for portability and excellent image quality, use a mirrorless Sony or whatever. If you want to put on...

    Re: Old Things,Farms,Barns,Buildings, Plus

    I get similar results with a Darlot pillbox landscape lens, normally f22, but if I unscrew the front of the lens and leave just the brass tube and rear lens, I calculated f9 for mine. It's one of my...

    Re: E-Bay and PayPal: What should I know?

    For those who want to protect themselves at all cost against any possible type of fraud, consider that your local convenience store could easily stop shoplifting by allowing customers in one at a...

    Re: E-Bay and PayPal: What should I know?

    It's pretty much the only game in town for obscure or rare photographica that isn't worth thousands of dollars. Some things I have learned after selling for 20+ years and dealing with Paypal and...

    Re: 65mm lens comparison

    If you have an itch to try it, scratch it. You never know how you're going to like something until you do. Some people love ultra-wides and use practically nothing else. I've shot wildlife with a...

    Re: Resolution Comparison Between Films?

    About 0.2? 3 stops lower than the lowest setting on my Pentax V. I bought 3 100ft x 12" rolls for $20 ea, IIRC.

    I'm not going to comment or speculate on military technology, but for a couple of years I experimented with a Konica imagesetter infrared film, on a rather thin base. There was a very noticeable...

    Re: 65mm lens comparison

    I guess the real reason is that I can't compose an image in my mind with a 65mm. My 75mm sees pretty much what my 90mm sees only a little bit wider, and behaves exactly the same when shooting. It...

    Re: Help choosing a "soft focus" lens, please.

    The Aero-Ektar is a fad, shallow DoF + flare =/= soft focus. The Verito is probably the most successful soft focus lens in history. Kodak Portrait is probably #2 on the list. It would be easier...

    Re: 65mm lens comparison

    Not trying to rain on your parade. I spent years looking longingly at these since I wanted something wider than 90mm on 4x5, before finally buying both a SA 65/5.6 and a Fujinon-W 75/5.6 within a...
  12. Re: Which State is the Best State for Landscape Photographers to Live?

    Re: Will a fire alarm light fog film?

    If you stand with your back to the fire alarm thing on the ceiling, so you're blocking the direct path for the light, you're probably safe for the few seconds it takes to pull a sheet out of a box...
  15. Re: Are the higher shutter speeds on large format lenses always off?

    The relevancy about slide, er, chrome film was simply that we no longer live in a world where having your exposure be off by 1/6th of a stop will get you fired from your day job (apologies to anyone...
  16. Re: Idea pitch: Electrochromic glass shutter, would it be possible?

    This absolutely would work for large barrel lenses, but only behind a Packard shutter. Of course if you're going to go to the expense of buying a large Packard shutter and putting this together, you...
  17. Re: Are the higher shutter speeds on large format lenses always off?

    Oh dear, I may have derailed a rather pointless discussion on shutter speeds and it's turned into an equally pointless discussion on 1990s commercial product photography, from my contention that the...
  18. Re: Are the higher shutter speeds on large format lenses always off?

    This is no longer possible. The film supply and labs do not exist, even if the technical knowledge to do so may live on for a few more years.
  19. Re: Are the higher shutter speeds on large format lenses always off?

    I figured the flashlight would be running PWM, but if that's running above 5 or 10K Hz the effect on my speed testing of a 1/200s shutter doesn't matter. Also, I suspect the PWM is only used to...
  20. Re: Are the higher shutter speeds on large format lenses always off?

    I shoot negs, and develop in cold water to exhaustion. Mostly because I scan instead of printing, and I didn't have a scanner that could adequately scan chromes (why I stopped shooting chromes). I...
  21. Re: Are the higher shutter speeds on large format lenses always off?

    Nice! I figured that since I'm measuring time, not light, I don't need the amplifier, I can simply use a strong enough light source that the tail ends of the curve that don't get measured are...
  22. Re: Are the higher shutter speeds on large format lenses always off?

    30 years ago there were a sizeable number of commercial photographers who earned a living doing large format work. I was not one of those. There were a lot more people losing money pretending to be...

    I've always respected people who live their life on their own terms (including taking their life when they're done), even if they make choices I wouldn't. That's why I have no problem with people...
  27. Re: Are the higher shutter speeds on large format lenses always off?

    I think we've established already that center-mounted shutters in modern lenses will not cause vignetting, as they are at the optical node of the lens. However front and rear-mounted leaf shutters...
  28. Re: Are the higher shutter speeds on large format lenses always off?

    The whole point of using lenses wide-open these days is for the effect, not because we're sports or news photographers tying to stop action with fast shutter speeds. Not that lf can't do that, just...
  29. Re: Are the higher shutter speeds on large format lenses always off?

    The Sinar sales brochure illustrates in a very understandable way why one should never use a Sinar shutter outside a studio with strobes. I don't think that was their intention.
  30. Re: Are the higher shutter speeds on large format lenses always off?

    The use of a light integrating sphere is superfluous, as the variable being measured is time, not light. The light measurement is merely a proxy, so all you need is some sort of apparatus...

  32. Re: Are the higher shutter speeds on large format lenses always off?

    There are 2 issues that I raised in my post. 1 is the 'true' shutter speed. I said you need to measure the total volume of light passing through the shutter and divide by the opening to get a true...
  33. Re: Are the higher shutter speeds on large format lenses always off?

    This applies at wide-open apertures since the shutter blades are usually in very close proximity to the aperture blades, but there are few circumstances where you would stop down to f32 then shoot at...
  34. Re: Are the higher shutter speeds on large format lenses always off?

    Someone who remembers their integral calculus from uni could do the calculation of the average amount of light that passes through a shutter given that the blades open then immediately close, so the...

    The lightest one. Or the one with the best shutter, but in both cases it's probably the Wolly.

    Re: Photo travel by vehicle, what's your favorite?
