        Really?? Boy this gets "confusedor & confusedor".  Someone says EI
250, someone says ISO 200. Some say use the filter on the lens before
metering, some say meter, open up for filter factor and add the filter. I
really can't understand why one would meter through the filter and then open
up more. Wouldn't it also be easier to assign an ISO  to the film, use
either reflected or incident meter reading and state which and if reflected
is being done from a gray card and then apply the filter factor for the
amount of additional exposure required?
