With significant banding in your sky....
There was no banding in the "AA masterpiece" version, simply because I turned the sky into completely black (ie, "AA black")
... Or do you prefer "bending"?...
Thanks for catching the typo.
... But that does not give you the right to dismiss we who are less able than you to process an image. But please explain ...
Again, I am not sure what I did to provoke such a tone. I do not remember "dismissing" you or anyone else. I just said I do not understand your point.
So, let me step back and explain from the beginning.
1. Black sky question. Why so black? Two reasons: AA is known for such a black sky, hence I dubbed my result, jokingly, as ""AA masterpiece." Second reason is that I used a method that resulted in banding unless the sky is completely black (thus hiding the banding).
2. Why I used such a method? I was trying to
quickly illustrate the point that there are opportunities for different interpretations of a "tourist snapshot." It was supposed to be an
illustration of that idea, not a contest who can provide the best processing. The method I used is a standard b&w conversion method, which, when used with a RAW, produces reasonable results most of the time. With jpeg, that method resulted in banding in less than black sky.
3. Is there an alternative and better ways to handle that sky in LR? Absolutely. I suggested one such way myself (using GND and vignetting - effectively reducing exposure in the sky). You did the same, just decreasing exposure a bit more. But please note that both your and my attempts resulted in losing the white cloud crispiness, turning it into gray. Also, if one is after an even darker sky, using your and my method of reducing exposure, the banding is going to start showing - it is just the nature of working with a compressed jpeg.
4. Are there even better, more precise ways to handle the sky and preserve the clouds? Again, absolutely. One can use an adjustment brush in LR to select the sky (checking the Auto Mask option), thus bypassing the clouds. Or, for even more precision, one can go to Photoshop and use a plethora of masking options there. Any such method requires more time than I was willing to spend on someone else's jpeg, trying to
illustrate the point, not trying to defend my "reputation."
