Hier hat jemand eine dcraw-Version entwickelt, die die pixelshift-Resultate zusammensetzt und Ghosting reduziert:

Kostet einen Amateur anscheinend ein paar Stunden. Wie lange es wohl die bezahlten "Profi"-Programmierer von Adobe, Dxo usw. kostet?

Example usage:
dcraw -T -4 IMGP0121.DNG
outputs a 16 bit linear tiff for your prefered raw processor to apply sharpening, white balance, etc
By default it wil detect artifacts by unexpected changes in the green channel. This is possible because we have two samples of green at each pixel.
Artifacts are repaired by the bayer interpolation on the first image.
-G sets the threshold, by default 20%. -G 100 or larger will disable, -G 20 sets the threshold to 20%
By specifying -v it will highlight the spot in purple. This can also be usefull if you want to repair manually.
And a compiled windows version:
