Just an experiment of Pixel Shift in Rawtherapee on the first MacOs Sierra release. I didn't know where to put my pictures to illustrate differences between with and without Pixel Shift rendering. For the experiment, I used a Leica Macro-Elmarit-R 60/2.8 @4.8, Iso100, 1/3s on a tripod with natural light coming from the back. I underexposed the picture by 1.3 EV according to the exposure indication and pushed it to +1.65 EV at RAW process. Besides, after Tiff conversion I used LR6.8 to push "clarity" to +30 to watch the different behaviour between the two pictures... sRGB Jpeg conversion made in LR6.8.
Img1799 = with Pixel Shift and Img1800= without Pixel Shift.
the First picture with Pixel Shift module & the Second one without Pixel Shift module.
the First picture with Pixel Shift module Crop100% & the Second one without Pixel Shift module Crop100%.
the First picture with Pixel Shift module Crop100% & the Second one without Pixel Shift module Crop100%.
the First picture with Pixel Shift module Crop100% & the Second one without Pixel Shift module Crop100%.

To summarize, with Pixel Shift after DNG conversion to Tiff pictures in MacOs Sierra RawTherapee:
- dynamic is better,
- colour scale is also richer but subtle,
- less noise,
- smoother tonality transition,
- better resolution..
After Tiff conversion to jpeg, differences are more marginal except for resolution... So you actually won't see on these jpeg pictures the differences although they exist... PS to be reserved for photo enlargement or to get better dynamic on static subjects... and so more..
Originally posted by heckflosse Not only on static subjects. The motion correction in RawTherapee pixelshift works quite good. In fact that was the part of pixelshift in RawTherapee we spent most of the development time, because other software we tested mostly failed at motion correction (sometimes miserably). Of course for regions with motion you won't get the advantages of pixelshift, but for regions without motion (the static parts in same picture, maybe that's what you meant by 'static subjects' and I misunderstood) you will get the advantages (better resolution if region is in focus, less noise ...).
The point is that current opinion was to avoid using pixelshift when there is motion in the scene, especially moving water. With RawTherapee that's no problem anymore.
