The Grand Central Station transparencies were made from large format originals. Some were shot with 9 x 18 inch aerial cameras; the one featuring the U.S. Navy "Blue Angels" flying formation over (I forget -- it was either Niagara Falls or Mt. Rushmore), for example. That one was the subject of a Kodak "documentary" film made at the time and used for promotional purposes. Showed pretty much the whole complex production process for the huge transparencies.
