Allow me to illustrate that a selection followed by a significant change to darken does not need to add a halo:
Starting from a section of your dark sooc image with two areas circled and no selections or changes. Notice that the circled area labeled \"1\" shows no white outline. The area labled \"2\" shows a one wide light colored pixel band between the light and dark zones. This is no doubt due to the sharpening applied in creating the jpeg. (The camera applies sharpening when creating the jpeg. This one pixel band ought *not* be there in the raw image, at least not until a program such as ARC adds some sharpening. The light band is a method sharpening uses to increase edge contrast to create the illusion of greater sharpness.
In the second example, I selected the inner area and applied an exposure layer to the inside using a selection to define the area to receive a 0.60 gamma change to darken the distance by increasing the gamma contrast effect. Notice that area \"1\" shows absolutely no light band. It wasn\'t in the original and it isn\'t in the selection modified zone edge. Notice that the light edge band in area \"2\" looks more obvious because the area beyond the band in the selected area is darker. Now if you put these images in Photoshop and use the eye-dropper on the pixels in the band of the before and after images, you will see that the band RGB values haven\'t changed at all. They became not noticeable because they stayed the same and the light area next to them became darker. If the one pixel wide band bothers you, the solution is to start with an unsharpened image that doesn\'t have the pixel wide sharpening artifact band to start with once everything else it right, you can then sharpen appropriately.
So the question is how you did the selection and how did you refine edges? I would probably use the magic wand to select the inner area or perhaps Topaz Remask. But then I am lost when it comes to refine edge. I have learned refine edge in the past, but with such poor results that I did not do it frequently enough to memorize the steps.
