re: pixel ghosting and pink/green artifacts. we don't do anything clever about that either, because i think it's more useful to get radiometrically correct output in case everything was setup to align.
the one stupid thing we do is look at the full 2x2 bayer block (starting around here https://github.com/darktable-org/darktable/blob/master/src/control/jobs/control_jobs.c#L305 ) to avoid colour casts especially for highlights which are clipped in the individual images. not sure even this is feasible with those hardwired raw add functions on digic. cheers, -jo On Tue, Oct 28, 2014 at 7:48 AM, Josep Vicenç Moragues Pastor < jose...@arrakis.es> wrote: > > I have the same issue with CeroNoice, by A1ex, from the MagicLantern team. > > (see http://www.magiclantern.fm/forum/index.php?topic=9581.0) > > It's a similar HDR merging utility, also based in Zeronoise technique. > CeroNoice outputs a 32-bit float DNG, and Darktable (current Git version) > cannot open these files. > > A1ex says that 32-bit float DNG is necessary to allow enough dynamic > range with extreme bracketed series.
