The IMAX camera uses conventional 70mm film which runs through the
camera horizontally. This produces a negative twice as large as if
run vertically as is done in normal movie cameras, assuming the same
aspect ratio. I don't know precisely which type of film they used
but special AERO versions of regular films are made for aerial 
photography. These are formulated to help reduce atmospheric haze,
etc. Perhaps one of these where used. But then there is no haze, nor
atmosphere for that matter, 200 miles out so that might not be a
worry. On a related matter, I don't recall the 'blads being loaded
with any kind of special film, even on the moon missions, except that
the base was especially thin, so more frames could be cramed in the
magazines. Any peculiar images may be due to the quality of the
release prints.
