Tiffen 4x4" ND 1.2 SG (used)

A used Tiffen 4×4″ Soft Edge Graduated 1.2 ND Filter (often called a Tiffen 4×4″ NE 1.2 SG) is a square graduated neutral density filter that darkens the top part of the image by about 4 stops (ND 1.2) while leaving the bottom clear, helping you balance bright skies with darker foregrounds without changing the colors in the photo or video.
