I wonder why the manufacturers don't incorporate three things into their
film scanners:
1. Move the film in a curve past the sensors. This would have two
advantages:
a) Curving the film would make the film flatter in the dimension of the
sensor.
b) No mechanical limit on frame length
2. Eliminate holders (except for slides) and support unlimited roll film
length and automatic scanning into a new directory.
3. Autodetect frame edges, especially on MF film. A rotary "Frame Length"
dial on the scanner could indicate frame sizes, which would be useful for
MF, half-frame, or subminiature scans.
I suppose the only downsize would be increased risk of scratching, but that
risk could be reduced by having rollers detect the film width and restrict
handling to the edges, which would be practical if the film always takes a
curved path, and never a straight one, through the machine. This would keep
the film from bowing in the middle.

"The moment one gives close attention to anything,
even a blade of grass, it becomes a mysterious,
awesome, indescribably magnificent world in itself --
Henry Miller, 1891-1980
