The 1981 Kodak Professional Dataguide gives more recipcrocity data for Kodachrome films. For those who venture into these long exposures. (The films may have been changed since 1981, but these numbers are consistent with the data in the chart already.)

Kodachrome 25: 10 seconds +2, CC10B, 100 seconds +3, CC20B.

Kodachrome 64: 1 second, CC10R.

The same would presumably apply to the professional versions.

Anybody know what "M" and "R" stands for? I remember in school we were taught that whenever you make a chart or graph, you *always* include a legend that defines everything the graph. One cannot assume others know everything you're talking about. I know and understand reciprocity, but I do not get the whole xM +xR stuff...
