Yanding Neutral Density Filters exhibit consistent spectral transmittance characteristics across the visible spectrum, regardless of wavelength. This makes them an optimal choice for precise exposure control in color photography, as well as for managing light in various measuring instruments.
Available in a standard size of 50x50mm square, these filters can be acquired individually or as a comprehensive set. The following 14 standard options are offered, each with a unique level of light transmission: ND0.3, ND1, ND3, ND5, ND10, ND13, ND20, ND25, ND30, ND40, ND50, ND60, ND70, ND80, corresponding to transmission rates of 0.3%, 1%, 3%, 5%, 10%, 12.5%, 20%, 25%, 30%, 40%, 50%, 60%, 70%, and 80%, respectively.
