Thanks for your reply. Usually I take 3 or 5 photos with different exposures and make a DNG file of them with HDRmerge (via user commands) or with enufuse (also with a user command like you made). Very occasionally, with a single shot of say a sunrise, the editing can be useful, especially as the sky gradually gets lighter or darker. I then make the intermediate exposures, as it were (note: this translation is not in English, but in Googlels 
)
Manipulating the dynamic range directly in art works very well (the only thing I sometimes have trouble with is selecting the dots in e.g. an equalizer because they are so small in a high resolution screen)
