Fog…

If you can see further than a kilometre it’s mist, less than a kilometre and it’s fog .

Image 109 – What’s in an image? Sometimes quite a lot, more than meets the eye. I’m posting an image every day or so.

Here’s a foggy day about a year ago, captured by my camera. When warm, moist air mixes with cold air – this is the result. Some of the moisture condenses into tiny droplets, distant objects are obscured, and closer object lose much of their contrast and colour. Everything looks washed out and grey.

Everything is still (even a light breeze will sweep away any hint of fog). The world seems mysterious because so much is hidden from view. Do you know the difference between fog and mist? it’s all about what is hidden from view; if you can see further than a kilometre it’s mist, less than a kilometre and it’s fog (technically). But in everyday life it’s normal for the cut-off to be much closer, around 180 metres.

Time for a Haiku, perhaps?

Cold and damp and grey
