When I was looking at your print of this image last evening I wondered if
it's possible that whatever occurrence you experience with the sky area of
this image might not be attributable to noise, rather than a busted
histogram. I assume when you fatigue the the shy it's is through darkening
it, and/or adding contrast. This always seems to expose defects in film and
scans for me. If you were to apply an equal move in the opposite direction
instead, i.e., lightening it how would it look? Heck, lets really test it.
If you put an equal move of lightening/flattening the area AFTER your
darkening/contrast move how does it look? Such a yo-yo move should really
kill the histogram - how much worse for wear does the sky look after the
fore and aft, compared to no move at all?

Isn't testing fun??????
