The large boar is showing how hot and bothered that he is while chasing his potential mate. That isn’t dust around him. It is steam coming off his hot body in the cool Alaska morning air. Used negative exposure compensation to darken the scene to emphasize the highlights.
It was towards the end of mating season for the coastal brown bears from Lake Clark National Park. Love was in the air with lots of mating action going on.
1/2000 @ F7.1, ISO 6400, evaluative metering, -2/3 exposure compensation, 500mm, R3 + 100-500, uncropped
