Thanks for Your suggestion Dalth500 :) I wished to show exact colour and brightness of a sky. I tried to redevelope it with 1 EV more - but the main theme (sky over power-plant) isn't so well preserved then. I would try to get another shot with tripod (with ISO100) so I could make it more HDR but for that shoot it is all what I could get from :) Thanks again for Your vote about this photo.
