Does anyone on the list know anything about processing PixelShift images in

Hi David,
I've repeatedly used make_arq [1] and it worked well for my A7R III so
far. It creates the combined ARQ image. A7R IV should be supported,
too. However, the resulting ARQ is supposedly not compatible with the
original Sony software, which may or may not be a problem. I don't
care about that, because I don't have any windows machine where I
could install the sony's software anyway, but it is something to take
into account if you need interoperability.
I've found scattered steps on handling them in RT, but nothing beyond
processing the individual images. Nothing about combining them.
You can process the resulting ARQ file pretty much the same way as you
would your ordinary ARW files in rawtherapee. If I recall correctly,
the only difference is that you get some additional settings for
demosaicing and motion correction in case there is a movement between
the frames.
I don't know how well the motion correction works though. I've used it
only for static images – scanning negatives to be exact.

Thanks. I finally got it to run, it seems to produce good results even
with handheld shots from my A7R IVA.
