What really gets me sick are the quite huge purple areas in the skies, these do not seem to me the same blotches one finds in the shadows, they are present also in the highlights. What is strange is that in the Develop module of LR5 (using ProPhoto RGB) these purple areas are much less visible than in the Library module that, if I correctly understood creates sRGB previews. I don't know if the problem is also linked to mappings/translations between color spaces.

Claudio, is there anywhere you could put the worst X3F on the web so I can download it for analyis in RawDigger and for converting in RawTherapee?

sure Ted, many thanks for spending some of your time in trying to help me (and maybe somebody else with the same problem)

you can download a .x3f file (iso 100) where I see the phenomenon (it is exposed to preserve the highlights in the white stones on the right, I know it is slightly under-exposed and this probably accentuate the problem, but in highly contrasted scenes is always difficult for me to perfectly expose with this camera)

you can also download the .jpg of the same file I obtained by adjusting the .x3f file in SPP 6.3, exporting it as .tif 16 bit in ProPhoto RGB color space, importing the .tif in Abode LightRoom5, and exporting it from LR5 in sRGB without doing anything

I would post the conclusions, if any, here for your information of course.

Also there is Kalpanika, have you tried it yet?

no, I'm sorry, I'm not a techie, with Sigma cameras the workflow is already relatively elaborate, I would prefer to avoid to add another step (even because I normally adjust quite a lot of parameters in SPP)

many thanks in advance Ted

ciao
