was used, and not a moving lens Panoram or Circuit camera.

A careful look at the distortion seen in the faces near the edges and corners shows that this was shot with a rather conventional 12x20 Banquet Camera, as was common in the day. These cameras used a somewhat wide angle lens and a wide aspect ratio film/plate format.

The Panoram (moving lens with fixed position curved film) and Cirkut (whole camera rotated during exposure) do not produce this type of distortion. They do produce a different alteration in the image. The Kodak Panoram swung the lens and moved a traveling slit across the pre-curved fixed position film. The Cirkut cameras rotated as a unit with the film moving past a slit.

Tterrace, thanks for the details on how the camera worked. Both times when I was in a convention where they took our picture with a banquet camera, the photographer gave a brief explanation beforehand but I don't remember him going into detail about the rotating lens or that kind of detail, so I never knew how it moved or what moved. I don't think I was close enough to get a good look at the camera, other than it was Big! It was in the early 1990s that those pictures took place. I bought copies of both of them. I wish I knew where they went. Ours were in color. Hope I find them one of these days.

There's no way in the world so many people would (or could, looking at some of the wine carafes in the room) hold absolutely still while a camera panned across the room. This shot had to have been taken as one wide photo by a camera with a panoramic lens. Panning a still camera creates a "wiped" or blurred image.

[These types of photographs were popular enough that the cameras used were commonly called "banquet cameras," large-format view cameras that had a motor-driven rotating lens, hence the need for the crowd to remain still for the duration of the exposure. They used sheet film that ranged in size up to 12x20 inches, exactly the size of the photo that jonnyfixit scanned; so this is a contact print made from such a negative. - tterrace]

Well, once again my place has had me put in it. However, I repeat my belief there was no way that big crowd and those musicians stayed perfectly motionless for such a photo. Impossible.
