Has anyone established a good way to know in advance exactly how much exposure compensation is necessary using a polarizer at various settings?
I do not have behind the lens metering.
The thought occurred to me that I might be able to pre-caliberate a polarizer using various settings and later take it into the field.
I have access to an evenly illuminated daylight light table and a very accurate Minolta one degree spot meter. Could I take readings through the polarizer on the light table at various settings, mark the polarizer, then use it in the field. There I can work with the compensation values I previously marked.
Another question arises - would a linear polarizer fool a one degree Minalto spot meter into giving inaccurate readings or would it be best to use circular polarizer? I understand a circular polarizer is used with modern electronics.
Does anybody have any suggestions or a fast accurate way to use polarizers at various settings with a view camera that does not have electronics ? Only a hand held one degree spot meter will be used.
