67mm Neutral Density (ND) Filter Set
Theft not covered.
This 67mm Neutral Density Filter Set is used to reduce light intake for contrast, long exposures, or shallow depth of field. The set includes 3 neutral density filters; .03, .06, and .09 capable of darkening a scene by 1-3 stops of light.
These filters are very popular for sunsets, where you need to keep the shutter open long enough to expose the foreground without overexposing the background. They are also good for shooting waterfalls during the day where you can hold the shutter open long enough to get that creamy, flowing look to the water. An absolute necessity when shooting video on a camera that does not have built-in ND filters.
4x = ND.6 (exposure adjustment = 2 stops, reduces ISO 1/4)
8x = ND.9 (exposure adjustment = 3 stops, reduces ISO 1/8)
