Bellows, photographic
Bellows are used to change the focal length of a lens to any length in its range. They are placed between the camera and the lens. They are held in place on a rack which allows the bellows to be extended or compressed with precision. Extending/compressing the bellows changes the focal length which in turn allows the lens range, image size and field of view to be changed.
