In chemistry, absorbance or decadic absorbance is the common logarithm of the ratio of incident to transmitted radiant power through a material, and spectral absorbance or spectral decadic absorbance is the common logarithm of the ratio of incident to transmitted spectral radiant power through a material.he optical depth equals the absorbance times ln(10). The term absorption refers to the physical process of absorbing light, while absorbance does not always measure absorption: it measures attenuation (of transmitted radiant power).
1 At a lower gain, the noise decreases, but the shutter speed becomes slower to compensate for the lack of brightness, causing camera shake or subject blur.  When recording using [Smth Slw REC], the upper limit of [AGC Limit] is [15dB].
ACC active state â the ACC system is in active control of the vehicle's speed. ACC speed control state â a substate of 'ACC active' state in which no forward. vehicles are present such that the ACC system is controlling vehicle speed to the. 'set speed' as is typical with conventional cruise control systems.
