I am very confused.
Tried desaturate, or convert to gray scale in ACR or convert to black and
white in photoshop.
But not sure how to post process.
Do you post process color before conversion?
Why do I get these gray banding effect in the sky? All i did was desaturate
color and adjust levels and curves.

黑白照片其实在lr里作初调挺方便的。在HSL/color/B&W那一栏，切到B&W，然后调整各
个颜色在黑白效果里的亮度。在photoshop里主要就是做dodge/burn了。

Any idea about the gray banding?
seems not enough tonal range but how did that happen?
Did post processing with color (used luminosity masks), then decided dun
like the color (blue and yellow) and converted to b&w. Maybe that is why the
gray banding happened?
Really like the image except those bands hurt my eyes.
