The HDR images are foul, in my opinion.
I'm sorry for the strong use of the word, but the colours look gaudy, the tones are flat, and there is awful halo-ing around edges.
The original image, or 'normal' one, looks awesome - well exposed, detail in highlights mid-tones and shadows, sharp, excellent composition.
As far as formal elements go, I can't get past the processing on the first two. They look fantastic as far as shape and line goes but the processing, I'm sorry
HDR can do some wonderful things with the right shots, IMHO these are not the right shots. What were you hoping the HDR would do?
