Blue Sunset

This photo was taken from the Pajstun castle ruins in Slovakia, around sunset. It was actually quite strange, how blue the sky was. Usually when I take sunset photos I get a lot of shades from pink to purple, but this sunset, it was just shades of blue. And all other photos taken around this time are also very blue :). I tried to play with the temperature of this photo, to make it a little warmer, but then I lost the beautiful shades of blue in the sky, so I let it be.

HDR from three shots, taken with Canon 450D with Sigma 10-20mm lens, from a tripod.
