The Cokin A121M Graduated Grey G2 Medium Filter ND4 is a part clear, part neutral density filter. It has progressive graduation from the middle to the top of the filter and has same colour as 121 but lower tone. It allows the transition to be blended into the scene often imperceptibly. A ND4-to-clear density with a two-stop differential will generally compensate the average bright sky-to-foreground situation.
