1. A method of controlling a lighting array comprising at least one partial spectrum lighting component to light a subject captured by a camera according to at least one target spectrum having at least one target partial spectrum component, the method comprising: capturing a subject image with the camera; computing a magnitude delta relative to the difference of the magnitude of the spectrum of the subject image and the magnitude of the target spectrum; for respective target partial spectrum components of the target spectrum, computing a partial spectrum component delta relative to the difference of the partial spectrum component of the subject image and the target partial spectrum component; and adjusting the lighting array relative to the magnitude delta and the respective partial spectrum components of the partial spectrum component deltas.
