    compensation?: number

    Exposure compensation in EV stops. Defaults to 0.

    highPercentile?: number

    Bright-tail percentile retained by metering in [0.51, 1]. Defaults to 0.98.

    keyValue?: number

    Middle-gray target luminance in [0.01, 0.5]. Defaults to 0.18.

    lowPercentile?: number

    Dark-tail percentile excluded from metering in [0, 0.49]. Defaults to 0.02.

    maximumEV?: number

    Maximum automatically selected EV in [-15, 15]. Defaults to 8.

    maximumLogLuminance?: number

    Highest log2 luminance represented by the histogram. Defaults to 16.

    metering?: AutoExposureMeteringMode

    Metering pattern. Defaults to center-weighted.

    minimumEV?: number

    Minimum automatically selected EV in [-15, 15]. Defaults to -8.

    minimumLogLuminance?: number

    Lowest log2 luminance represented by the histogram. Defaults to -12.

    sampleStride?: number

    Histogram sampling stride in pixels. Defaults to 2.

    speedDown?: number

    Adaptation speed when exposure decreases, in inverse seconds. Defaults to 3.

    speedUp?: number

    Adaptation speed when exposure increases, in inverse seconds. Defaults to 1.5.
