Century 4x4 ND.6 SolidSKU 70-C40406
The Century Precision Optics 4x4" ND 0.6 Glass Filter enables you to adjust exposure without affecting colour balance. Neutral density filters are available in 1, 2, 3, and more stops to suit individual situations.
Determining which neutral density filter yields ideal results for any given lighting situation takes knowledge, experience, and a collection of such filters. Choose the filter strength that adjusts the lighting to stay within the exposure latitude (greatest difference between bright/dark values) which still shows details in both of the digital or film medium in use.
Speaking generally, the 2-stop value (ND 0.6—the filter's clear portion allows 4x more light to pass vs. darkest portion) effectively compensates average situations.
