Dear Everybody,
The attached image is a panorama, created by automation in Photoshop CC. It comprises six JPG taken hand-held (rotating about my waist) and cropped after photomerge. No processing of original images before photomerge.

Look closely at the horizon line and you can see a line of light and dark stripes, like dashes on the horizon. Note also that the sky, as seen through the trees which are silhouetted against the sky, is much lighter than the sky above and to the sides of the trees.

What causes this and how do I get rid of it? My efforts with a cloning brush are abysmal. And I can't imagine that my talents run to manually merging the photos.

Grateful for any help. :lol:

PS. The image is of the Sturt Plateau in the Northern Territory, Australia
