      • kCIImageToneMapHDRtoSDR

        @NotNull
public static @NotNull java.lang.String kCIImageToneMapHDRtoSDR()
        A boolean value specifying whether an image returned by [CIImage with...] should have kernels applied that will tone map to standard dynamic range (SDR). The option will only have an effect if the image has a CGColorSpace that is high dynamic range (HDR). This option can be useful if further usage of an image is not prepared for HDR values. If the value for this option is @YES, then the HDR input image will be tone mapped to working space SDR. If the value for this option is @NO, then the HDR input image will be linearized to unclamped working space. If this option is not specified, then it will behave as if @NO was specified. API-Since: 14.1
