A UV (or Haze) sounds ideal as it is supposed to have a 1.0 factor and "should" only affect spectra non-visible to humans. I've known about the effects subjectively but always wondered if it could be objectively quantified. Can you include what aspects of the filter tested "bad" and some idea how bad is was (if possible)?
