This is an animation I made showing Saturn and the rings. It is based on measurements of calibrated Cassini images and should be fairly accurate, for example subtle effects like ringshine on Saturn and Saturnshine on the rings are included. The main inaccuracies I know of are that I brightened the rings at high phase angles to make them more visible and the unlit side of the rings is also too bright for the same reason. Another problem is limited dynamic range - the rings' opposition highlight is very bright so I had to darken it a bit. Otherwise I would either have been forced to 'overexpose' a fairly large area in the rings or make Saturn darker than I would have liked. Also for this reason the rings are a bit too dark relative to Saturn at 'medium' (~60 degrees) phase angles, despite the fact that as previously mentioned I brightened them at high phase angles.
