    “This is part of why we know that the famous photo of construction workers on a girder was actually a staged shot. That … and the fact that there are other much-more-clearly staged shots from the same sequence of photos.”

    Were all the photos on the NY Times blog entry taken with the same long exposure? I don’t know how you would hold the flapping flags in photos 3 and 6 still for 2 seconds.

      Reading further into the note about film speed, that’s two seconds at f16.  Change to f2 and you’re at 1/8 a second.  The shooter might have done some extra work during the developing process to get another stop, possibly two.  Now we’re talking about 1/30th of a second.

      However, all of this is moot since the author also concedes ” the slow speed of 1/2 ISO is very close to what emulsions were in the 1870′s.”  I have to imagine that sixty years after that they had techniques that allowed for faster work, 1931 gave us Harold Edgerton and the first stop motion photography.

      Probably not. That particular image lacks the blotchy look of glass plate photographs. 

  2. Is that what Forbes’ Insoluble Dry Plates were?

    I didn’t get the chance to see that particular glass negative, but I did have the opportunity – years ago – to visit Corbis’s storage facility for that and a *lot* of other negatives (including many of the original glass plates with Lincoln’s portraits).  Its buried away deep underground in an old granite mine (IIRC) in Northwestern Pennsylvania.  A number of Federal agencies have storage facilities there too, along with the World Bank and ESPN and Disney.  Naturally, its out of the way and well-guarded – but the benefits of a nice dry, climate-controlled facility (with reliable energy) make it an ideal location for storing the sensitive negatives.

    Nice overview of early photography. Back when I was a very young, budding photographer, I used to have to ask the dinosaurs to hold certain poses for 10 or even 20 seconds to get the right shot. Photographic images were made on huge slabs of lava rock and were developed in dark prehistoric caves. Aah, those were the days…! Digital is so much easier, isn’t it?

      What did you use for chemicals?

      • mccrum says:

        Every shooter had their own various combinations of roots and berries.  These were tightly kept secrets, handed down from father to son.  Eventually, families rich in heritage and steeped in tradition would merge and recipes would be shared between clans, making the whole stronger than the two original parts.  Many were to perish through the years, but Olan and Mills maintained strength through cunning and skill eventually joining forces to defeat the mighty Sears family of portrait photographers.

    It isn’t “two whole seconds” to get an image on a sunny day. With a lens aperture of f/4 (possible with some plate cameras of the day), an exposure of 1/8 of a second would be about right. Still not easy, but possible.

  6. welcomeabored says:

    I’m not normally afraid of heights, but every time I see that famous photo, I feel just a little woozie, and am struck again by how brave, macho, and maybe a little foolhardy you had to be to work construction then on skyscrapers.

    The subjects in the photo look so ‘just-another-day-at-the-office’.

  7.  Photography was quite advanced by 1930 and amateurs had been taking many fine images with hand held cameras (requiring short exposure times) since 1900 or so.  The numbers quoted above for exposure times sound very far fetched.  I can’t imagine a reason the chemistry on glass would be any slower than on regular film.

    • Alpacaman says:

      The chemistry was significantly different, and much less controlled than on modern films – also, the numbers are from home made plates. So, while reasonable in the very specific case of the photographer in the alternative photography link, plates of the time were often faster than this.

  8. Alpacaman says:

    This article could really have been better researched. The linked piece on dry plate work is good, but higher speeds can be achieved, and were. A lot rests on how the age of the emulsion, how quickly it was mixed, the colour of the light used (less sensitivity to yellows often), whether is was made in a factory with tight controls on these things etc. etc.

    So likely the film was of a much higher speed, maybe around 4 is likely I think? With that speed, and a wider aperture of 5.6, then the shutter speed on a sunny day comes to 1/30. Much more manageable.

    That is conservative, I think. Glass plates were often factory produced then, allowing for much greater speed and consistency between plates.

     “That meant that, wherever photographers went, they had to carry an entire darkroom with them.”

    Not exactly. They weren’t developing the prints on site, so they did not need an “entire darkroom”. I agree with the above commenter, this article could have been better researched.

  10. This is a history on Photography, not a history on this particular photograph.  A miss leading title to say the least.  L2title articles.
