Shooting a Panoramic Photograph
On a cold December day, some Library of Congress staff members volunteered to be the subjects of a demonstration of how a panoramic photograph is made.
When shooting a picture, the Cirkut panoramic camera moves in an arc from left to right. The people in the front row are arranged along a corresponding arc, so that in the finished photograph they will seem to be standing in a straight line.
While under the hood, the photographer focuses the picture. Unlike a 35-millimeter camera, a Cirkut camera has no mirror and prism to reverse the image, and the photographer sees the picture upside-down.
The aperture is "stopped down," to allow only the proper amount of light into the camera. The back of the camera is loaded with film, and the gears are wound so that when the picture is taken, the roll of film and the camera move in perfect synch.
Photographer: "…We're just about ready to photograph you, but I first need to explain a little about the camera. This is an antique panoramic camera. It works a little differently from what you're used to because it does not take a snapshot. It takes a timed exposure, so you need to hold very very still. If you move during a timed exposure, you'll turn out a blur…"
The photographer sets the angle of the arc that the camera will travel and releases the wound gear advancing the film and rotating the camera on the tripod. As the camera rotates it photographs one section at a time until it has exposed the entire length of film.
And here is the end result:
