I only had (battery) time to record TL about 5 minutes so clips were short but stretched them a bit by slowing frame rate.
Next time we get this effect I will max it out could go for at least 20 minutes

Very fine pictures

I've seen fog in the Weald of Kent sloshing about in slow motion, oscillating to be higher on the northern side, then back to the south and repeat with a period of about an hour, lasting nearly all day.

The surprising thing is though you can discern movement while watching or normal speed video it is actually moving much faster than you might think.
I find quite often you look out and see at least some fog like this, but by the time you get a camera sorted out it has almost gone - so a very brief ephemeral thing.

Very nice footage!
