Fog acts as a natural soft box and diffuses the light and if you shoot without adding some plus exposure compensation, the picture will come out dark. When I have the scene focused in my camera, I take one shot and look at the histogram. I want to expose to the right to give me the greatest amount of information, so that I can adjust the picture in post-processing. In shootings scenic, I use the lowest ISO, a sturdy tripod with a good head, single shot mode, mirror up and a shutter release. If I am doing single pictures of the scene, I utilize Aperture Priority. But, if I am doing a panorama, in order to keep the same settings I would use Manual Mode.
