This watchtower called “De Duiventoren” is located in Heusden, Noord-Brabant. Heusden is an old fortified town (old as in first mentioned in 722). The city walls are much younger of course, this tower was built around 1355 and was rebuild in 1984.
The photo is a HDR. I took 3 exposures (-2,0,2), handheld, which I converted to 5 TIFF images (generating a -4 eV and a 4 eV exposure). After generating a HDR picture, I did some adjustments to tone down the greens. Then some sharpening and a little vignetting.
