BearFruitGray Illuminant Spectra


The graph below shows the spectra of the bluish, greenish, reddish, and yellowish illuminants used for the BearFruitGrayB, BearFruitGrayG, BearFruitGrayR, and BearFruitGrayY images respectively. These spectra show the light reflected from the matte Munsell N 9.5/ paper in each image (see location R in the locator image), multiplied by 1.12 to account for the fact that the reference surface does not have a refletance of unity.
