There has been a definite improvement with respect the the DNG files. The colour haze in the top left quadrant is now gone. The only issue remaining for me is that Light Room still will not recognize the Panoramic DNG files for importing into the catalogue. It seems that Bridge recognizes them and when I open the raw files in Bridge and make some adjustments to them afterwards they will load easily into Lightroom. Go figure. Maybe its my settings in Lightroom, I don't know. Would appreciate knowing if anyone else is having this issue.
