Fog is such a wonderful thing to shoot but it's actually really hard because you need to find the right subjects and balance between what is obscured by the fog and what is clear in the image. Too much of either one and your images won't look like it's foggy.
Shot with the Nikon D750 and Nikkor 70-200mm f/2.8. The only wide shot here is taken with my phone because that is all I had on me.
