Whitelees windfarm with 140 turbines, is the largest in Europe. This turbine is 110 metres high when the tip is at its highest point. This picture is from below where the noise in a steady wind was impressive, but 2 minutes walk away, inaudible. Sigma 10-20 is good for this kind of thing even though I criticised it for edge sharpness in my blog recently. Polariser on and on tripod to get a tiny bit of tip movement at least, even at f22 it was so bright that I didn’t get much!
