Abstract: A method and an apparatus for spectrum synthesis for use in a flash unit, wherein the spectrum synthesis includes combining a plurality of emissive light sources in order to provide a combine output beam and producing the output spectrum for the combined output beam at least based on a reference spectrum. The reference spectrum can be obtained by sensing the spectrum of ambient light or selected from a plurality of stored spectra. The flash unit has at least two emissive light sources and each of the light sources can be adjusted relative to each other so that the outputs from the light sources can mimic a selected illumination scenario. It is possible to use a mixture of quantum dots to tailor each light source so that the combined spectra from different light sources can reasonably mimic a number of frequently used illumination scenario.
