The International Museum of Photography at the George Eastman House in Rochester, New York, has provided us with a picture of the Number 4 Panoram Kodak, the ingenious machine with which Isabel Walker Drake took the views of her Corning family (“An American Panorama,” April, 1975) When the button is pressed, the lens swivels to the left in a quick transit, setting down on film a large slice of whatever the camera is pointed at.
