These Photos were taken with a 50 year old Panon
camera. It uses 120 film and makes a 2x4 1/2" negative by painting
the image onto the film in a 1/8" wide slit. Later models of the
Panon were called Widelux and are sold today in 35mm and 120 formats.
Shutter speeds are 1/50th, 1/200th, and 2 seconds. For the "2 second
exposure" the lens takes about 1 minute to travel from the left side
of the camera to the right side, giving a 140 degree field of view with a 50mm
lens.
The design of the camera makes it very difficult to expose the entire frame consistently as the lens sweeps the film. If the drum speeds up or slows down ever so slightly during its travel, it will produce vertical bands of different exposure across the frame. These are somewhat present in these photos although in very severe cases I have removed them with Photoshop.
This picture was taken with a 90mm
lens for a 4x5 but on an 8x10 camera. It shows the full image circle.
I had intended to crop it to a 4x8 panorama but decided I liked it better as is.
The 90mm on an 8x10 gives an angle of view of about 100 degrees.
I had intended to use a half slide and make two 4x10 pictures on one 8x10 negative
but the 90mm lens compressed the bellows to the point that I couldn't shift the image away from center.
In the future I intend to sacrifice field of view and use the half slides to make panoramas that way.
