Anyway, your comments on brightness and saturation are well taken. They
need a bit of extra attention imo, even if correct. The whole use of
finish is still under my scrutiny.
Scale variation: yes, you are absolutely right and I want to get a
better control on the distribution of the different grains. What in
particular is missing in this "matrix" is quartz, besides the
salmon-coloured feldspars. Literature gives the (varying) proportions of
each and can serve as a guide.
This is going to be the next step now for me with this test granite. As
soon as I get something working I shall post the code for everybody to
test and shoot on (if they feel the urge).
