TheCokin Z-Pro Series Graduated Blue 0.7 to 0.4 Filteris designed for use with a Cokin Z-Pro Series Filter Holder. Its graduated, edge-to-edge coloration can be used to create an intentional blue effect, which features gradation, over an entire image. The filter is densest at one edge with up to a 0.7 density that tapers to approximately a 0.4 density at the other edge. This filter's 0.7 to 0.4 density range corresponds to a reduction of light from entering a lens by two and one-third of a stop to one and one-third of a stop.

This filter is made of durable, optical resin (CR39) and measures 1.6mm thick.
