I have been noticing moiré in several Fujifilm RAW files (.RAF, X-Trans).
Here is an example:
RAW file: https://dl.dropboxusercontent.com/u/2171814/_FFX7922.RAF
XMP (RAW): https://dl.dropboxusercontent.com/u/2171814/_FFX7922_01.RAF.xmp
JPG (SOOC): https://dl.dropboxusercontent.com/u/2171814/_FFX7922.JPG
XMP (JPG): https://dl.dropboxusercontent.com/u/2171814/_FFX7922.JPG.xmp
There is moiré in the blue shirt in the RAW file, but not in the SOOC JPG.
(Take a look, e.g., at the area between his camera and his vest after
zooming in.) Even with Markesteijn 3-pass demosaic + five times color
smoothing I still see moiré.
I wanted to find out whether this is a Fujifilm-related issue or a
Darktable-related issue, so I asked a friend to open the RAW file in
Lightoom (version 5.7.64) and export a full resolution JPG. (Since all my
computers rum Linux, I do not access to LR.) Here is the resulting JPG:

I see no moiré.
Is there a way to get rid of moiré in X-Trans images when using Darktable?
Comments and tips and welcome. Best, Francisco
