As you probably know I'm a great fan of Photomatix Pro's Details Enhancer algorithm. However, recently I started to use Fusion/Natural it offers quite a lot. For instance I used it to process the image above. Why? It produces very natural looking images and noise isn't a amplified. For these reasons I will probably update my HDR tutorial soon to describe Exposure Fusion as well.
