1. A method for identifying an imaging property for a scene by using an imaging assembly which has a spectral response which is tunable in accordance with a capture parameter, the method comprising: applying a first capture parameter to the imaging assembly, and capturing a first image of the scene using the imaging assembly whose spectral response is tuned in accordance with the first capture parameter; applying a second capture parameter to the imaging assembly, wherein the second capture parameter is different from the first capture parameter, and capturing a second image of the scene using the imaging assembly whose spectral response is tuned in accordance with the second capture parameter; and identifying an illuminant for the scene based on at least one color channel ratio of the first image of the scene and at least one color channel ratio of the second image of the scene, wherein the illuminant has a defined spectral power distribution.
