Hi, years ago when money was tight and the need to make full use of what you had was a must, I would double the use of film by using a piece of black card to cover half the lens and take a double exposure on one frame, covering the top then the bottom giving two pan type images. If you took both shots from the same spot using a tripod and the same aperture and overlapping the central part of the scene an extreme pan was possible. A bit hit and miss I know but with a bit of trimming from the central part of the image where the top and bottom exposures joined it worked quite well. The resulting image would have the same resolution as a 35mm pan, but you lose the advantage of the full frame resolution, the reason why one uses a MF camera in the first place.
