Following up with the beach theme I want to share a photo of the sunset me and my wife were watching at Mareta beach in Sagres. The sky is very beautiful under the ocean. I would make a ton of photos depicting only different sky patterns.
This image is a HDR image made from hands using 3 photo with steps in 1EV.
This is another example of HDR photo I made at evening. The idea was to make a photo against sun. As this tasks is not realizable by standard means I tried to use HDR here (additionally training in this technique). I think this is not the worst result ;-)
