What are we actually celebrating? The 35mm width is definitely older than
a century, although I know Edison used round perfs. Are we celebrating
modern BH or KS perfed 35?

Yes, Its been around since 1889 but an International agreement was
made in 1909 where most of the
leading countries of the world agreed to use the 35mm gauge for the
production and distribution of
films.
In 1908 Eastman Kodak started using the newly introduced Bell &
Howell perforators(before this
people had to perforate their own films) and these perforators were
far superior to anything available
up to that time. Eastman then started to sell its films preperforated.
This certainly encouraged producers to
adopt the 35mm guage and the following year the international
agreement was made.

Also, CS perfs were more "tear resistant" than any other perf.
It is generally accepted that the CS perf is LESS tear resistant because
of the narrower width of the sprocket teeth which act more like a knife
edge than KS, BH, or DH style teeth.

Oh I get it...because those early CS films were of a type less likely to
evoke tears than say Now, Voyager or Camille. |

Quote: So, why does film for 35mm still cameras have KS perfs?
The answer, and most particularly for Kodachrome, is: so the raw stock
won't be used in professional motion picture cameras, all of which (in
the West) have BH pins.
However, because the width of a KS perf is the same as the diameter of
a BH pin, and also beause the height of a KS perf is taller than a BH
pin, BH stock will flow through a camera designed for BH perfed raw
stock, but it will not register correctly.
Note: the height of a CS perf, although it looks like a narrower
version of a KS perf, is the same as the height of a BH pin.
This gives a better result in release printing, which was usually made
from the composited camera negative until the late 1960s.

Oops ...
However, because the width of a KS perf is the same as the diameter of
a BH pin, and also beause the height of a KS perf is taller than a BH
pin, _KS_ stock will flow through a camera designed for BH perfed raw
stock, but it will not register correctly.
(It will not register vertically because of the difference in the
height of the KS perf which is taller than the height of the BH "big
pin", and it will not register horizontally because that function is
dependent upon the "little pin" having the same height as the "big
pin", but not the same diameter. Western professional cameras do not
have a side pressure mechanism, rather these depend upon the "big pin"
and "little pin" functioning in concert to register both vertically and
horizontally).

Have you got a cite or details on the agreement? I run a short film
program at a local festival and would love to have a short bit about it
in the program for the anniversary.
