Thanks for the advice, it works! The pink and green motion artifacts are very tricky to avoid with any HDR merging tool that operates in raw data, I know. For such images is better to develop the raw files and merge the demosaiced images. Guillermo Luijk's ZeroNoise has some good antighosting

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://git

works for me: http://picpaste.com/2014-10-28-201346_1920x1080_scrot-1mSLfEXj.png it's only that our float dng are normalised to clipping at 1.0, and these have crazy high values in them. so you need to disable the highlight reconstruction module (see screenshot) and stop down by like 15ev (right

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

we already read the floating point dng that our hdr merger creates.. if the files aren't too different from that it should just work or need minor adjustments. -jo On Mon, Oct 27, 2014 at 7:06 AM, Pedro Côrte-Real wrote: > If it's a standard DNG it shouldn't be too hard. Could you please > subm

If it's a standard DNG it shouldn't be too hard. Could you please submit a bug report with an attached example file? http://www.darktable.org/redmine/projects/darktable/issues/new Thanks, Pedro On Sun, Oct 26, 2014 at 9:56 AM, Bert Blockx wrote: > Hello, > > Is it possible to implement the HDR

Hello, Is it possible to implement the HDRMerge DNG-format? http://jcelaya.github.io/hdrmerge/ https://github.com/jcelaya/hdrmerge This program is very good at merging a set of exposure bracketed RAW-files by combining the best exposed regions from each RAW-file. (Zero Noise technique
