Fog and mist often add to a photograph, giving it a softer, aesthetic look. Since fog and mist are generally a dawn phenomenon (water vapor condenses when temperature and dew point are within two or three degrees of each other) I got these shots early in the season since I live over an hour away from the field (I only had to get up at 4:30 to get these shots).
Since there is usually no wind associated with fog or mist, wind turbines are not likely to rotate, since they need at least a 4 MPH breeze. I was fortunate to have a view of some turbines on higher ground (where there was some wind) overlooking background mist on lower ground.
