This is a shot looking North from El Matador Beach. I think this is my third of fourth post from this one location alone. It's very photogenic.
This is a long exposure Night HDR photo. I used the three shots of the HDR to really make the colors come to life rather then giving it that "everything is perfectly exposed" look.
After the sun goes down you still have half hour to fourty five minutes to still get some great photos. You'll just be using longer shutters. I find that as it gets darker and your shutter is over a minute long, the light it absorbes becomes more and more less effective. It can start taking a very long time to shoot each shot.
