With all due respect, you are a professional photographer right? This is foundation level...
"Short rotation is a term used to define cameras that have a lens that rotates around the camera's rear nodal point (the optical point from which the focal length is measured) opposite a curved film plane. As the photograph is taken, the lens pivots around its nodal point while
a slit exposes the vertical strip of film that is aligned with the axis of the lens. The entire exposure usually takes a fraction of a second and the camera's functions similarly to the method of viewing a scene by turning one's head from side to side on a steady level. It is also referred to as rotating lens or swing lens. Typically, these cameras capture a field of view between 110° to 140° and an aspect ratio of 2:1 to 4:1. The images produced commonly take up 1.5 to 3 times as much space on the negative as the exposure made by traditional 35 mm cameras." - (

"In 1845, Friedrich von Martens, an engraver living in Paris, developed a camera which made it possible to take a 1500 daguerreotype view on a single plate. Considering that the human eye covers a field of vision of approximately 60' and early daguerreotype cameras only 45', this was an important breakthrough. The Eastman Kodak Company marketed a camera based on similar principles, the Kodak Panoram, in 1899. In this
camera the lens moves in an arc in front of a curved film plane. Snelson has used modern versions of this type of panoramic camera, particularly the Widelux, to take 140' views that are then pieced together to provide a complete circuit." - (
