Actually this is not a real HDR: only one RAW image (with enough DR) was converted with under and overexposure settings, the results were processed as HDR.
The reason was to utilize as much as possible details at shadows and highlights from the initial 12 (or 14?) bit RAW for the final 8 bit JPEG.
I have some concerns about the sky, but finally I think that it makes more contrast between the foreground and background.
What do you say, did it work?
