Hi Herb, I haven't a solution however I have a question for you. What shutter speeds are you achieving in most cases whilst using the filter? IS the cast the same colour for different types of film? Why I ask is I wonder if you are experiencing the effects of colour shift due to reciprocity failure of the film?
