Murat, I aimed to reproduce what I think I saw.
17 mm t/s lens on a tripod, mirror locked up, focussed in live view, 2 s shutter delay. ISO400, f/11, 1/50, 1/400 and 1/6. High ISO because the tripod was on thick grass and potentially wobbly. I took several series until the sun was no longer blown in the shortest exposure.
Processed in Photomatix. I used tone mapping, adjusting strength and smoothing to taste, quite high values. I find these are the most important for getting a more-natural look. I often do not tone map, I decide after looking at both fusion and tone mapping options.
Then a slew of fine-tuning in Aperture.
