This filter is a combination between a Neutral Density Grad 0.3 Hard Edge and an Autumn 2 Grad. The Autumn color graduated filter is double filter blending Tobacco and yellow to enhance color of foliage. Graduated NDs are available in Soft Edge or Hard Edge varieties. Soft edge grads have a smooth transition from clear to ND. Hard edge grads have a more defined hard lined transition and are usually used for longer focal lengths. ND Grads are made in different densities according to the level of light reduction from 1/3 to as much as 4 Stops of light. The 0.3 filter reduces light by 1 Stop. This 85mm filter is usable with Hitech 85mm holder systems or any 85mm (3.35"/P Size) holder.
