Thanks for the answer Lukáš! So, if open .hdr images in Hugin, I could only obtain a HDR output in EXR format. If ,instead, I want a enfused panorama I have to load the bracketed shots directly in hugin: I wasn't aware of that so thanks for pointing that out!
For the preview window, I didn't switch to LDR as you suggest. Now it's ok! Thanks!
