As far as being a Photoshop, maybe. I do see the light at her back and to the right on the towers.
Although I've been able to get a similar effect twice on the White Rim using neutral density filters, timing and a bit of luck. These are film scans and I did work on the first one at the light/dark boundary along the rim cliffs right along the sky to get some detail. The second is a straight scan and you can see the cliffs lost detail. The ND filter is a straight line and the world is not straight, so you have to compromise. The way to do it is take a few shots and make a composite, but that's a pro with a digital camera or unlimited film budget.
