That effect can be such a pain.

From some feedbacks, maybe I'll redo some color corrections tomorrow. So stay tuned...

it looks jpeg compression lowered color depth on darks and made it look worse.
have dithers on darks using slightly wavelet denoise on 16bit may make look better (or if you used graycstration on 8bit, try on 16bit instead) (￣▽￣)ノ

Not jpeg maybe, I think I've done the compression right. Also I think the banding comes from a wavelet-based filter, which can be known from the clustering pattern. The dark area is filtered with lower intensity to preserve details, and the banding got preserved also.

I think I'll filter some more mid-frequency in the dark area out with imagenomic tomorrow.

...Oh man I simply hate AM-screening printed large dark areas.

ah!... the long awaited planetarian poster i've been waiting for...

I still have a terribly hard time on dark areas without overly filtering them out to a blur.

Fortunately the black this time is sort of a background, so overfiltering a little isn't really a big deal.
