I have a post processing question about ethics. I have seen images of things like jockeys riding hummingbirds. Obviously a composite photo created in Photoshop. I have pictures of Mesa Arch at Canyonlands National Park. The arch spans over a 2,000 foot drop at the edge of a sheer cliff. If you look through the arch you can see the canyonlands mesa that stretches for miles and is a breathtaking view. The problem is that you can't take it all in form a single vantage point because the edge of the cliff blocks part of the view.
I took several pictures that encompass the entire spectacle. I wanted to see what it would look like if the edge of the cliff was a bit lower so that in one image, you could see both the arch and the mesa so I moved the edge of the cliff in Photoshop. As this is an impossible view, would it be considered artistic license or a breach of ethics? Unlike the jockey on the hummingbird, it may not be obvious that something has been moved. Your thoughts?
If you would like, I can post the original images.
