HDR obtained from 9 pictures (-4 to +4) and processed with Nik HDR Efex Pro. I find the Nik software to produce more realistic looking images than Photomatix. I also like Nik's anti-ghosting feature, not really necessary for this picture.
I also used Nik's Complete Edition tonal contrast filter to add some more detail.
I then removed any noise with Nik Dfine 2.0 and finished the editing in PS CS5.
Thanks for viewing =)
