A collection of liquid water droplets or ice crystals suspended in the air at or near the Earth’s surface. While fog is a type of stratus cloud, the term “fog” is typically distinguished from the more generic term “cloud” in that fog is low-lying, and the moisture in the fog is often generated locally. Fog is distinguished from mist only by its density, as expressed in the resulting decrease in visibility. Fog reduces visibility to below 1 km (5/8 statue mile), whereas mist reduces visibility to no less than 1 km.
The sensation that fog or any condensation adds to photography is one of mystery, one of magic. The eeriness that those little water droplets can add to a scene may bring forth visions of fantasy. What lies within the clouds? The way that light intertwines with moisture in the air adds to the atmosphere of the landscape. Not only are you mystified by what lies behind the curtain, the mist can add the feeling of surprise, fear and admiration.
We had a few days when the fog stayed with us until the late afternoon- a rarity in our parts. We were lucky to be out in countryside on these days traveling the back-roads of Southeastern Minnesota lucky that we could share this abnormality together. Next time the fog rolls into your area, grab your camera, and capture the light that dances gracefully with the water droplets. Be quick though, the fog can form and then dissipate just as fast.
