At the end of 1991 I finally bought my first panoramic camera, a Japanese Widelux F8 which I couldn’t really afford. It was a camera that took around 21 pictures on a 36 exposure film, with the film curved around a part of a cylindrical path with the lens pivoting around the centre of the cylinder.

The lens is a 26mm f2.8, though it needs to be stopped down to around f8 for most pictures as the camera is fixed focus at around 6 ft and only gets sharp at infinity when stopped down. Winding on the film winds up a clockwork motor and returns the lens to its starting position. On pressing the shutter the lens swings around through about 140 degrees, exposing the film through a slit at its back which swings across close to the film. It has 3 shutter speeds, 1/15, 1/125, and 1/250th, but even at the fastest speed it still takes rather longer to actually complete the exposure.

The design keeps lens to film distant constant – at around 26mm – right to the edge of the film across a negative 24mm x 56mm. If this was flat, the distance to the corner would be more like 40mm and so objects at the edges get stretched to around 1.5 times actual size. This camera eliminates this distortion, but at the expense of introducing its own which you can see in these pictures. This becomes particularly noticeable in the curvature of most straight non-vertical lines.

In particular, horizons become curved unless the camera is kept absolutely level. The pictures of Bow Creek were made with the camera on a sturdy tripod and with the help of a spirit level. There is one on the top plate of the camera, but I found a larger separate one more useful.

Although the angle of view is often stated as 140 degrees this is perhaps misleading and I think probably is the angle across the diagonal. Rather more useful is the horizontal angle of view, which I think is just slightly over 120 degrees. Theoretically it would be possible to create a full 360 degree view in three exposures, but practically it needed four, though I don’t think I ever succeeded on the few occasions I tried to make one.

Later I made many more panoramas here and around London, particularly with a similar Russian camera, the Horizon or Horizont which was rather more convenient to use, as well as a few with a much larger medium format version. I also used a Hassleblad X-Pan, a nice camera which was panoramic only in format, with a similar negative size, 58x24mm, but using rectilinear lenses which can’t acheive a really wide angle of view.
