Cameras can accurately reproduce color that humans interpret across scenes, but the actual reflectance spectra of the object cannot be accurately reconstructed with only 3 color channels. We explore using multiple LEDs as illuminants and various methods of reconstructing reflectance spectra of skin and other objects.
