How does the human non-image-forming visual system represent, encode and process light and color?

I am interested in how light affects our brain, physiology and behaviour beyond what we consciously see and perceive. I am specifically interested in the short-wavelength (blue) sensitive photopigment melanopsin, which aids in synchronising our bodies and brains to the prevailing light-dark cycle, and in controlling the size of the pupil.
