For this wider shot of Clatteringshaws Loch, we used a focal length of 50mm and focused on a rock a third into the scene. With a narrow aperture of f/16, this ensured everything from the foreground rocks to the mountains were sharp. It was a flat-light kind of day, so we exposed for brighter sky to retain some darkness and detail there, leaving the foreground underexposed. In ACR we used the Grad filter tool to brighten the foreground, and another to darken the sky.
