The 40.5mm Heliopan FLD Fluorescent Filter for Daylight Film is a color correction filter that is designed to reduce green casts when shooting with daylight film under fluorescent lighting. It is constructed from Schott glass for optical clarity and a brass filter ring is featured for durability and jamming prevention.
This filter's 2x filter factor results in a 1 stop exposure reduction, and a plastic case is included for storage and transport.
