This is a set of 4
Blender Neutral Density Filters: 0.3, 0.6, 0.9 and 1.2 densities.
A blender is the same as a graduated filter, but with the transition taking place gradually over the whole length of the filter rather than in the middle.
Blender NDs are available as standard in 0.3, 0.6, 0.9 and 1.2 with heavier densities available to order - please
