Syntax

float AutoExposureMinBrightness

Remarks

Auto-Exposure minimum adaptation. Eye Adaptation is disabled if Min = Max. Auto-exposure is implemented by choosing an exposure value for which the average luminance generates a pixel brightness equal to the Constant Calibration value. The Min/Max are expressed in pixel luminance (cd/m2) or in EV100 when using ExtendDefaultLuminanceRange (see project settings).
