@Judy: No horizontal shots with these colors. This was taken as I was climbing the stairs leaving the beach.
@Macrobaby: Good to see you back. I initially used HDR to deal with a range of light that exceeded the capacity of my camera; i.e., I was always going for the realistic look. Lately, I have been have fun playing and pressing the envelope a bit.
@marc battault: Hard to believe that I almost missed it. I just happened to turn around while climbing up from the beach.
@StarCosmosBleu: It was magic, but technically speaking, it was the Blue Hour (that hour after the sun goes down).
