When I see clouds behind someone (especially in shots with angles like this), I tend to think that they are legitimate clouds unless there is obvious Photoshop. There was a very long time where natural lighting was preferred over artificial lighting for shots like this.

Why would someone go through the immense effort to make artificial lighting look like natural lighting when natural lighting is already there and it's completely free?

Are photoshopped clouds more normal than legitimate clouds now? Did I miss something?
