Replacing Bland Skies In Photoshop

[ameerat42]

Assuming you use Photoshop, start at post 5, above.

I'm not sure of the question, as any such process will involve some selection
of the areas to be changed. Does your cutting refer to the original image?

My approach would be to use something else from another image to paste
into the image you want to change. Again, that means making a selection.
