Just to add more info than you wanted, if you are using a hand meter, or spot
metering, the neutral density of the pol. is about 1.7-1.8 stops. What you see
as the variable in a TTL meter is the reduction of glare in addition to the
neutral density factor. The ND remains the same regardless of how it is
turned. Presumably if you are spot metering, you are not metering the glare,
and you only adjust for the ND factor.
