This was taken summer before last from the window of my old flat in London.
It was about 30 mins before sunset, and the colours of the sky and clouds
suddenly went berserk. This was just a snapshot taken to record the bizarre
sky (and to check that my eyes weren't playing up.......), and before I had
time to come up with an interesting composition, it'd disappeared.

The colours are as genuine as they ever are from Velvia - no post-production
apart from straightforward levels adjustments in PS.

Tech: Nikon F3, 70-210 f/4 zoom at 210mm, ?ap ?exp(seconds), Fuji Velvia,
tripod.
