Cloud movement was brought up recently about the Lake Chelan scene. I ran
into the same situation the other day with a distant shot of some mountains.
Since they were miles away, I shot a number of images while walking left to
right, and another sequence walking back. The left-to-right set looked odd
because of the cloud movement, while the right-to-left ones worked out. The
clouds were moving right-to-left also. No cloning used.
