These photographs were taken at 10.30 the other night and it still wasn't quite dark...
The Purkinje effect is the name given to the way we see at this special time of low light (it occurs just before sunrise too, I'm told) when certain colours, especially those in the blue spectrum, seem to glow from within.
See yesterday's post and read more about this fascinating phenomenon here, and here, and look out for it just after the sun has set and before it gets dark.
Magical.
