We can consider HDR to be a very specific tool for crazy fanatics, as well as on the universal tool usable by various photographers, from purely artistic ones, to reporters. It really depend on the way you take it. Personally, I love to use all kinds of HDR, I enjoy one way of post process inside the church, completely different in the landscape. I just play... :-) Finally I would like to HDRsoft, who gave me a free licence of Photomatix.
