No, I make a duplicate or copy image, not a duplicate layer.  Click on
"Image" in the top bar, then click on "Duplicate."  It will be labeled
"Copy."

The curves are applied to the entire images.  Usually my selection is saved,
so I forgot to say that no selection should be on the image at this point.

I'm probably not using the right terminology.  Use the "Alt" key with the
clone/rubber-stamp tool to set the input/source point at the upper left
corner of the duplicate/copy image, then click on the original image at the
same exact point to be sure the pixels are exactly matched.

This is where the selection has to be on the original to restrict the
cloning to the areas you want to be the tone of the duplicate/copy image.

If you were trying this with layers, it might have gotten confusing.

Hope this helps.
