Today I had an assignment to photograph the Christmas tree being installed in Trafalgar Square, for the 70th time since Oslo began to send this annual present to London.  I hadn't realised that under the paving there's a shaft containing some heavy duty machinery to keep the tree stable in high winds.  Luckily for me and everyone else involved though, there was no breeze at all and a clear blue sky from (very) early morning until late afternoon.  More like the November weather I'd expect in Cape Trafalgar than WC2.
