I am working on a high resolution Saturn map. It can??t BE Saturn as i
haven??t got enough data for it, but my aim is to make a reasonably
realistic representation of Saturn, if not entirely scientifically accurate.
I use bits and pieces from recent Cassini images, and fill in the gaps
with imagination and low resolution where there are no good images
(mostly the nothern hemisphere).
The southern hemisphere isn??t too difficult, but i need help in finding the
right color tones and on how much detail to let through: i am very unsure
how much of these cloudscapes that ought to be visible. Here??s a test
(this is a rough draft, there is much detail to attend to that isn??t addressed
yet here):
Top left: Bj??rn Johnson??s original.
Beside it: the same one, with added noise to get some structure to work from
Next: part of a mosaic of Cassini images, as near the area as i can manage
Last: a blending of the "noise map" and the Cassini mosaic, together with some blurring filters and coloring.
Below: a series of tests to determine "true colors" and visible detail.
... These images are downscaled 2k from 8k. The end result will be a 4k
map. The last test is what i feel will be most realistic, but i don??t know
enough about the Ciclops imaging techniques to decide.
Opinions, please?
