All digital cameras have very, very narrow dynamic range, compared to film.
Highly dynamic scenes like yours are a problem. You have groups of
entirely washed-out pixels, and surrounded by more pixels that are color-
aberrated.

This would seem to require some kind of non-linear optical filter to
correct (does that exist?).
