Here are the details:
This photo is made with a Pentax K100D and Sigma 10-20mm wideangle lens.
First, I made a HDR ( 3 pictures, 1EV difference). Processed the 3 images in Photomatix.
Then, loaded the HDR-photo in Photoshop. Converted in black & white, Finally, I merged the B/W photo with the color-version. Made adjustments: dodge, burn,... Et voila....the result.
Not a bad effort. A couple of weaknesses for me though are the heavy darkness in the top of the tree - guessing a bit too much dodging went on there.
Then there's the owl - the perspective looks wrong. I'm guessing this was shot more of less on a level with it. So it doesn't match with the top of the pillar which was shot from a much lower angle. The effect is that it's leaning forward.
