Don't know why, but photography from some places seems to lend itself to HDR conversion better than others. Could be the photographer's inspiration. Some of the best HDR work I think I've done comes from Vietnam (Here are a few), a place I love, and I really liked Addis Ababa and the Ethiopian people a lot more than I'd expected to. So maybe that's it.
The top photo is from St. Mary's Church on Mt. Entoto, outside Addis. In the middle are worshippers at Trinity Ethiopian Orthodox church in Addis, and at the bottom we're back on Mt. Entoto. Click them to make them bigger. All these were shot with Nikon gear, converted in Photomatix and finished in Photoshop with Nik filters.
