I was playing around with compositing in an image of the moon into a landscape. The blend worked pretty well but there is a tiny outline of the moon image layer showing. You'll have to download the image to see it. It's definitely not on the original moon layer. See image below, as well as Blending Mode info.

Thanks for any assist in getting rid of that line!

Just a guess: Try unchecking Inner Glow.

Does the moon layer have a background layer? Or said another way, when the the moon layer was created as a solo image, did moon fail to fill / over-fill the pixel size of the canvas used to create that image? That is: does the slight frame of the moon exist in that file but doesn't show when viewed on a white background? If you crop the moon to say 99% or 98%, does that eliminate the frame when placed behind the tree a second time?

A few swipes of the "Smudge/Darken" tool in Photoshop eliminated the white lines

I have seen this before. I believe there is an issue with PS CC, not your process.

One fast way to correct it is to do a layer and correct this with a patching tool. Avoid smudge or the like that will disturb the pixel pattern and create unwanted artifacts.

Three more comments:
- PP: The foreground trees are covered by the moon
- PP: The moon has a black strip around it.
- Camera sensor has dust on it.

If you need help on creating this, please post your originals and ask folks to work on it.

Excellent guess! The border disappeared instantly. Thanks!

Thanks--it turned out to have been caused by checking "Inner Glow." I had checked the layer against a dark background to make sure I wasn't just missing it.

Thanks for all the observations. I hadn't fussed with the blending because of the border. Adjusting the "Underlying Layer" put the moon 100% behind the trees. Another tweak eliminated the black strip.

Adding the layer to restore the image below the border was a great idea! Had unchecking Inner Glow not worked, this strategy certainly would have. Really appreciate your thorough response.

All is well thanks to Hogs. Probably for the 500th time!

Your moon element was not isolated properly. Even without the glow effect, it will still be over the tree.
Have it as a masked layer to control/adjust the edges & overlay.

Proper compositing rest on how the elements were isolated/selected and layered. Simple blending with clouds may come out with passable quality but many objects require controlled or advance selection & editing of edges and visible layering.

An overview for controlled compositing are:
1. General adjustments
2. Active layer*
3. Isolation/selection copy*
4. Paste on a new layer
5. Arrange/Order the layer*
6. Edit/add effects/blending*
7. General adjustments
8. Fine Adjustments

Those marked with * are crucial to outcome quality of the image.

Here are a few examples of compositing/editing using selective copy/paste & blending/edit;

Those lines are your square picture edge from the moon shot. Erase them with a large soft edge brush or in a mask.
