I think there was a multiple exposure here. 1 was for the side of the ship's hull (in the shade), and the other was for the background.
I suppose this could have been achieved in a single exposure, with FILL-IN FLASH.
So it doesn't count as HDR.... sorry!
I feel that there is too much white in this photo to be striking.
The dynamic range is also limited, so after PP it will look 'normal', or like what ZerocoolAstra said,
achievable in a single exposure if there is sufficient lighting on the hull. (not with a flash though)
original underexpose pic have good sky details but super dark ship hull and the foreground floor, normal expose pic can see details of the ship hull and the details of the ship in the background but sky is all white, last over expose picture have clear details of the ship hull and the railing and ground but sky and back ground ship totally wash out
agree... does not need to look like a painting... but here.. i cannot see the HDR...???
Maybe bcos the sky is too blown... but if it's under-exposed actually u can do some rescuing i think.... you can even layer several tweaked versions of the same photo to bring out/ dumb down the details...
