Apparently you failed to understand my question about IR cutoff. My Zone VI digital (Pentax) has been modified to cut off IR influence that occurs when you photograph foliage...in particular green foliage like pine trees. Does this meter eliminate IR influence in those situations?
Without IR cutoff, a meter will be influence by IR emissions in addition to visible light and thus will indicate an erroneously high meter reading and hence an underexposed negative.
While your description of color influence may apply to other meters it does not apply to the modified Pentax. I have tested the modified Pentax over twenty years of field use and found that I can meter through filters with definable results.
I am not trying to diminish the meter that you address or your enthusiasm for it...I am just trying to determine what this meter is honestly capable of doing.
