Sure it is. You're arranging what elements of the scene you're including. Now, if you mean manipulating elements of the scene (removing trash, moving branches, etc.) that would be different.
i couldn't agree more with you ...
i had this conversation with someone a few years ago
regarding manipulation as well because no matter what you do
as soon as you put the camera to the eye, "frame" / compose it in the viewfinder
or ground glass it is manipulated, and arranged, just as when you use fast or slow shutter speeds
or different depth of fields its all manipulated + constructed ...
basically people with cameras construct their own reality by choosing how it will be viewed.
some people do this masterfully and are paid handsomely as "stylists" others rely on
the natural disorder of things to arrange the scene for them ..
