I've seen quite a few posts of photographs manipulated by the "copy-paste" technique. Just taking an element from some other picture (it could be the moon, a cat, a plane, clouds, etc.) and pasting it into the photo, supposedly "enriching" the composition, or achieving some pseudo-technical achievement. I believe that in the past such a thing was considered "heavy post processing", against the TOS, and the posts deleted.
