Hello, Mike Waterman: > [...] > Footnote: shiny spheres have no phase factor. > [...] When observed from the shadow side, even shiny spheres can be dark. So, *there is* a phase factor <;3)~~~~. In fact, a smooth perfectly reflecting sphere (no diffusion) is a case where the phase factor can be theoretically calculated (but I have not yet do it - maybe during the next train-traval).
