The original photo was way under exposed. The camera metered (figured out how much light was available) for the background (ie, the very bright sky) and decided on a short shutter speed. She was pretty much a silhouette on the hillside. There wasn't much texture in the sky (solidly cloudy) so I didn't lose much by digitally exposing the entire photo more, and then further lightened the face. And added this post-apocalyptic color scheme.
