Thanks for this interesting and accurate post...
Speaking of dead nomenclature, we have yet to cover the
Weston, GE and
GOST standards!

I think I may have something on GOST somewhere and I do
have a description of the Weston method. I have never been
able to anything on the General Electric method although the
is probably something in the literature.
The important thing about Weston is that they had the
first independant speed testing program. Previous systems
were open to cheating by the film manufacturers who
sometimes made their films seem faster than they were.
Weston, and I think GE, did the testing themselves. I will
write more about this later. I've just come home from work
and am fried.
