Here are the details:
This photo is made with a Pentax K100D and Sigma 10-20mm wideangle + circular polarisation-filter.
First, I made a HDR ( 3 pictures, 1EV difference) of the church. Processed the 3 images in Photomatix.
Then, loaded the HDR-photo in Photoshop. Converted in black & white, using the infrared option. I merged the B/W photo with the color-version. Made adjustments: dodge, burn, clone... Then added birds an lightning.... Et voila....the result.
