			The makernote is a special area of the EXIF metadata that any manufacturerer (maker) can define individually.

			The data saved in the Elphel EXIF Makernote includes the following fields:

			*double[] gains = new double[4];
			*double[] blacks = new double[4];
			*double[] blacks256 = new double[4];
			*double[] gammas = new double[4];
			long[] gamma_scales = new long[4]; /* now not used, was scale _after_ gamma is applied, 0x400(default) corresponds to 1.0 */
			*double[][] rgammas = new double[4][];
			*double min_gain;
			*long WOI_LEFT;
			*long WOI_WIDTH;
			*long WOI_TOP;
			*long WOI_HEIGHT;
			*long BAYER_MODE;
			*long DCM_HOR;
			*long DCM_VERT;
			*long BIN_HOR;
			*long BIN_VERT;
			*long COLOR_MODE;

			*boolean COMPOSITE;
			*boolean PORTRAIT;
			*boolean YTABLEFORC;
			*long QUALITY;
			*long CQUALITY;
			*long CORING_INDEX_Y;
