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 by using the imaging assembly whose spectral response is tuned in accordance with the second capture parameter; and comparing the first and second images of the scene to identify an imaging property for the scene.
