Even I tried the new DBE tool in PixInsight. I found it to
work pretty well on a fairly straightforward image (h and chi Persei), though I
did it at 4th order with no assumed symmetry on a 35 mm
negative originally scanned at 4000 dpi. (It might take a while to do these
computations on some platforms and it even took several minutes on my
computer.) Interestingly, application of the DBE tool resulted in
much less background noise than what I normally get using Jerry's method
which could mean I was misapplying something in my previous
efforts.
I still find myself going back to PS for curves and
levels. I couldn't get use to the curves tool in PixInsight and I hated giving
up the ability to do layers. I may try some more because I'm sure PixInsight is
very powerful.
