I was the Oregon Coast recently and I shot this photo of girl walking on the beach. The hot sun was causing the water in the sand to evaporate and create fog that hung on the beach. It made for a pretty neat photo.
The 200mm focal length 'pulls-in' the background. I shot at f2.8 to get maximum background blur, but I think this shot would have worked using any aperture. I used the +2/3 exposure compensation because the camera wanted to make the image too dark.
Here's one more shot from the same day:
