It was taken with the 200/2 AFS and a D2X. I and my field assistant spent several hours at the location, a hot-spot on the migratory bird routes to Norway, while the sun set and made the open landscape and sky awash in rich warm colours.
I am familiar with the scenery and knew the sun would set over the sea, so the the shots obtained the afternoon were just an exercise of patient waiting. After all the main subject was pretty stationary.
Although much of the landscape here is a Nature Preserve because of the migratory birds, in true Norwegian style a huge aluminium melter works has been put straight into the location leading to power lines criss-crossing the locality. This probably to maximise profit and collateral damage to birdlife, I suppose.
