1. A method of image rendering, the method comprising:
identifying a first light in a scene, the first light having a first representation in a first color rendering scheme (CRS) and a second representation in a second CRS;
identifying an attenuation function characterizing interaction of the first light with a medium in the scene;
determining, using the attenuation function, a third representation in the first CRS of the first light interacting with the medium;
determining one or more fitting parameters of the attenuation function based at least in part on minimizing a difference between the third representation of the first light and a fourth representation, in the second CRS, of the first light interacting with the medium; and
rendering, using the attenuation function and the determined one or more fitting parameters, an image comprising at least one of the first light interacting with the medium or a second light interacting with the medium.
