Pentax K70 supports pixel shift mode. In this mode 4 shifted frames are recorded… and available in the raw file.
[How it works](http://www.pentaxforums.com/articles/photo-articles/how-pentax-k-3-ii-pixel-shifting-works.html)
In first step we could allow access to each of the frames in rt. That's easy, as dcraw already supports that. We would need a frame selector somewhere in gui of the raw demosaic tab and pass the value (1,2,3,4) to dcraw.
I will make a new branch with a prototype to allow testing.
In second step we can define a new `'demosaic'` method `pixel shift` which combines the 4 frames to one image.
