[pure-silver] Re: filter factor

Since I don't know what brand meter you have or its age, let me warn
that trying to determine your own filter factor is iffy because your
meter's sensor may not be equally sensitive to all wavelengths.  This
was a problem years ago when SLR's first started including meters.
Metering with the filter in place often produced the wrong exposure.
Today's meters have a better spectral response.

Subject: [pure-silver] filter factor


I just bought a Hoya yellow K2 filter for a view camera lens. 
(Luckily it also fits my medium format camera.) I held it up in front 
of the spot meter today while metering  shadow areas, and it read a 
third of a stop less than without the filter.  So, does that mean my 
filter factor is 1.3?
