The amazing world around Saturn

Starting a new thread (this is an important aspect of space exploration and worth bringing forward).
Where are the shadows, the dark spots, darker areas, Saturnshine, snowy areas...Very confusing Iapetus!! It looks like it also confused Cassini's camera (over-exposure, under-exposure).
And it looks like the JPL people were very much aware of Clarke's influence.
I must have read about Iapetus (he wrote "Japetus") before reading his book, but only in a moons classification chart; Japetus became very much part of SF culture thanks to sir Arthur.
