Hi Max,
Sorry, I left out one important step in use of the layers. I use the same steps as you do except at the end, I flatten the image. This ensures that the effects of the changes on the background copy stays with the original image. If you delete the background layer, then all of your edits including the sharpening and selective erasing get deleted.
To confirm here are my steps:
1. Create background copy layer
2. Select aircraft only using "magic wand" or "quick selector." If it is an aircraft with a plain sky background, I use the magic wand on the sky and then invert the selection followed by expansion by 1 pixel (all available in the "Select" tab of Photoshop Elements. It is faster than selecting the aircraft. There may be similar functions in your photo editor. No point in sharpening the sky since it only introduces graininess.
3. Apply sharpening on background copy layer. Check for jaggies.
4. If jaggies are visible, use eraser tool on the jaggies on the background copy layer
5. Flatten image. If additional sharpening is needed, open a second background layer
5. Expand selection by 1 pixel and repeat sharpening and selective erasing. If you do not expand the selection, you might end up with sharpening halos.
6. If OK, Flatten Image.
You can PM me if you want some additional details.
