Konica rates film speed at 32 ISO for this film without use of a filter. But what is the correct ISO setting when using a Wratten #25 Red Filter with a M6TTL camera? I assume that the meter sees more light than it thinks it sees and that I should rate the exposure at about 400 ISO? TIA for any recommendations.
