Here are my images for this exercise. I ended up changing the blending mode and opacity of each blending mode to get the best looking image. The old photograph worked the best with the overlay blending mode set at 92% opacity. The other two blending modes do not allow the image to be as clear. The luminosity allows for much clearer color saturation on the sky and the mountains, I set a curve on the photo to allow for the shadows in the cliff faces to darken and to allow the tops of the mountains to illuminate more.
