Originally posted by biz-engineer I agree. Yesterday I've played with some raw images to try things out. Different parts of an image relate to each other, including contrasts. It's hard to transform a badly exposed image into a good one with post processing. Correct exposure of different par of the image is essential to be able to take advantage of the post processing. Applied light can reveal so much and give the extra headroom for the post processing. Then the post processing is a set of trade-offs.

I've tried that again yesterday and compared it to the unsharp method. Both methods do not give the same results but similar, the clarity / noise approach is more straightforward and allows to play with sharpness separately.
Guys,
I've played with something for a while. It is a Spatial Frequency by octave Photoshop script. You input you file and it outputs a file with the input, DC, and eight octaves as layers. You can then review to identify within each octave your weak or strong portions you wish to fix. I'm hoping that this extra separation makes the anomalies apparent for you.
Because these are normal looking layers, you can burn, dodge, whatever you wish to make stronger or weaker. Once you have id'd the areas and applied the cure, you can then run a companion script to put is all back together into a single layer. This Photoshop script is located at:
__SST-Save.zip. Unzip it, and copy to the script folder in Photoshop. This should run on Win or Mac Photoshop CC. The file used as input should not be your original but a copy and probably should be flattened before calling this routine.
The companion script is broken right now but try to see if Spatial Frequency separation allows you to identify the anomalous areas.
Have a try please and I'll fix what I screwed up in the companion.
Cheers,
RONC

Reason: Forgot mention that the script is Photoshop CC
