Sunsets: the Marmite of the photography world

Walking through my local park last week, I noticed an especially wild sunset: the sky overhead was an electric shade of violet, and stretching out into the distance over London was an entire spectrum of colour from vermilion red to lemon yellow. It was the kind of beautiful concoction that, in Britain at least, seems to be the preserve of mild winter evenings. And there have been more than a few of late.
