I've been working quite a bit with HDR recently, trying to improve my skills not only PP, but with shooting. Coming from the side of the tracks of those who do not like that radical, unattractive tone mapped look, and knowing what it takes to prevent it, I think you have done a pretty good job here. On one hand, I looked at the clouds and thought "oops, tone mapping", but then after looking again, I thought "but hey, I've seen clouds that dark and threatening before." So the clouds are probably on that threshold, but I'm sure you tweaked quite a bit to eliminate the halos and other problems. The branches of the trees are within register (but it's hard to tell on a small image) so I'm led to think this may be a single LDR image turned into 3 images. If this was indeed from 3 different exposures, then you did a good job there also. So all-in-all, I think you did a good job. One additional thoughts, tho. To me it looks like a shot that may have been achievable with a single frame. Keep sharing your HDR experience and workflow thoughts. /Dan
