Hello.

Example 6 was another difficult image.  Whenever I adjusted the image it seemed that the statue looked better but the background looked worse.  I suspect a mask would have worked good here.  I did, however, try to make an adjustment using Lab.  Unfortunately, I never saw the Statue of Liberty in person so I am guessing that the statue has a greenish color. 

Again, how would I determine a neutral for this image?

Please give me your comments.

Thank you
David

David,
I will agree that this is a tricky image but I have never seen an over cast sky that is green unless there is a storm nearby...While the sky might not be gray...it certainly should not be Green.
Shot1 shows your image with hue clocks...

Shot two is a LAB adjustment that removes the green from the sky by moving only the ends of the A and B curves slightly...
Since the sky is green start by adding red..move the red end of the A channel toward the center a few points and watch the numbers on the hue clocks.  then add some Blue by using the same process for the blue side of the B channel...

Us the arrow keys after clicking in the corner to select the end points.

Hello

I tried Example 6, the Statue of Liberty, again.  When I looked at the photo again, I noticed the greenish colors better.  I did not use the saturation slider as much because, I believe this intensified the green.  What do you think of the image this time?

Thank you
David

You probably could get away with saturation here...It' looks like you took too big of a step back.

Threshold the Shadows and then set a reasonable neutral on the sky.  Then add saturation.
It's in there but the whole thing rests on the neutral choice.
