Raw files from Fuji x100 (original, Bayer sensor): colors messed up (rotated, shifted, swapped?)

Hi all,

I opened up some old Fuji X100 raw files I had in my dt library to try some new editing and, to my surprise, the colors turned out to be completely messed up, even when resetting the history. I tried to file a bug on github, but it wouldn’t let me attach the raw file, so I am attaching it here together with its companion in-camera jpeg.

Has anybody noticed the same behavior? I don’t remember anything like this with previous versions of dt. I am using dt 5.0.1 on a macbook pro (Intel) running Sequoia 15.3.1, with the binary downloaded from GitHub. It makes no difference whether I enable OpenCL GPU processing (integrated Intel Iris) or not.

Any suggestion much appreciated
thanks!

Something is totally messed with the colors of this image. This needs imput from a more knowledgeable person than me. I can only confirm that something is crazy with the colors. Is this camera supported by DT? Did it previously to open correctly in DT? I am on a windows computer with DT 5.1.

Hi @Terry ,

Thanks for having a look. Yes, that’s exactly how it renders on my system. I am pretty sure dt converted it correctly in previous versions (but I can’t recall how many versions back). I tried opening with another raw editor and it looks fine.

Try swapping the “BLUE” and “RED” in cameras.xml for the “FinePix X100” (assuming that is the right model).

Sounds about right, thanks. I am not on that machine right now, so I’ll check it this evening. But is the “cameras.xml” file a setting file that is also read by the github-provided binary, or is it a file that is read at compilation time, when building from sources?

No need to build, it is parsed at runtime.

Indeed that worked! I will file a bug with rawspeed.

thank you so much
giuseppe
