The first image, the second image, and the first and second camera settings are analyzed () to estimate characteristics of the light source. The characteristics of the light source may be used to propose a replacement light source and characteristics of the proposed replacement light source may be used to simulate the effect of the replacement light source on the illuminated environment.
