We have so many misty days where I live, I even have a photo file with the name of mist. It usually happens in Autumn originating from the local River Aare. Of course this is mist for amateurs. It is a collection of moisture, clean moisture. You can breathe the air, no danger.
Here someone was cleaning something with high pressure water, also misty.
I am diverging. I grew up in London, born in 1946 and we were the professionals in knowing mist, although my memories of mist are more of smog. Smog was a result of clouds produced by industry, chemical and probably full of sulphur. Smog was yellow, deep intensive yellow. I would walk to school during the fifties. Luckily I knew the way as sight was reduced and you had to fight your way through a thick yellow curtain. I am sure if I had a knife I could have cut pieces out of the smog, it was so thick. I remember it had a smell, a smokey smell. Eventually I would arrive at school and cleared my nose with a handkerchief leaving black sooty deposits on the cloth, blown out of my nose. I would add that since this time, The Brits did something about it and eventually forbid using coal for heating, which was the main culprit.
Mist in Switzerland is something completely different. It even has its aesthetic side.
