This shot was taken while shooting a very active thunderstorm. The lightning was to the east and I had my back to the sunset, but I became aware of the stunning reds and purples bathing everything around me and I turned to the west to be stunned by this scene. Every other photographer on the hill that afternoon did the same!
The image was originally part of a Pano. The colours are as close as I could get to what I saw in person.
