Optical density is defined as the logarithm (base 10) of the absorbance ...
WebThe optical density of filters in series is additive (e.g., two 1.0 OD filters in series are equivalent to one 2.0 OD filter). Just as it is crucial to install a reflective ND filter with the reflective surface facing the incident light, it is also important to combine filters in series with all reflective surfaces in the same direction.
