Hello, I am using the latest release version of DT 2.4.4 (which is great and a big thanks to the developers!) and a camera with an x-trans III sensor (Fuji X100F). While everybody's recommending the markesteijn 3 pass algorithm for demosaicing X-Trans sensors, I have noticed that in dark areas of high ISO images this algorithm produces an unpleasant artifact, namely it tends to render noise in a kind of "tiny sticks" pattern, instead of the more organic original dot-like grain (you have to zoom in at 100% to see it). This artifact is not produced with the VNG algorithm, which on the other hand seems to create other problems (e.g. near high contrast edges) that are better managed with the markesteijn algorithm.
Any thoughts on this and how to solve the issue? thanks in advance for any suggestions PS: I have tried the 2.6 RC2, which is impressive (e.g. the defaults for noise reductions are *much* more sensible, and the filmic module is awesom). This particular issue, however, seems to have remained unchanged giuseppe ____________________________________________________________________________ darktable user mailing list to unsubscribe send a mail to [email protected]
