Here is a quick example of how adding light to a shot can transform an image. Top image as shot and bottom image as shot with flash thrown in the mix. I enjoy being able to change an image by simply using light to bring out texture in one way or another. This is a very simple technique but it does require a few tools to pull off. First camera on a tripod, a wireless flash sender on camera and receiver on flash and a tablet and camranger to fire the camera and see the image on the tablet. So in sequence, my tablet triggers my camera, then the camera triggers the flash remote, then my flash receives the signal and fires and finally my camranger wifi mounted to the camera sends the image back to me on my tablet where i can analyze if i need to move the light, add power or whatever and there is no need to be at the camera so it opens up a whole set of creative possibilities.
