yes for ISO 100, EV 14 2/3. Meter calibrated with K=12.5. it's 3251 Cd/m^2.
EV 15 it's 4096 like Steve said.
For ISO 1, EV 0 the lumination is 12.5 Cd/m^2 if K=12.5. If K=14 then it's 14 Cd/m^2 for ISO 1, EV 0.
Unfortunately my Weston Master II is no longer working. But to answer my own question if I were to calibrate it so that the number 400 means 400 Cd/ft^2 then I would need to set the film speed setting to 80 for and ISO 100 film then it will agree with a modern meter like the my Minolta flashmeter VI.
Same as mine but apparently different to Bill's.
Mechanically, what does the dial indicate when you do that?
For example: Emulsion Speed 80, Pointer 1/3 stop below 400 Cd/ft^2, f/16 is opposite what shutter speed?
For me, what I'd call the US Master Version (to contrast it with the UK Master Version) it is opposite 1/130
