Both software packages read the blended 4 image file created by the camera software.after which you are able to convert to Tiff using your choice of protocol or standard

Originally posted by Rondec My question is what these various softwares are doing with motion between the images. It feels as though a lot of software just opens the first image which is fine for a preview, but defeats the purpose of pixel shift. Others just bluntly combine them all, but do not allow for motion correction. If you are just shooting in door macro shots, it doesn't matter, but for real world shots, you need some flexibility. I would say that when I am shooting water with pixel shift, I tend to use the median setting as this gives some blurred appearance to the water which using standard motion correction doesn't do.
At this point, thanks to a lot of work by heckflosse and others, Raw Therapee really does seem to be the most flexible software with regard to pixel shift development.
I'm not familiar with the K1 but the within the firmware package for the K70, Pixel Shift Motion correction can be applied to the blended image within the camera at the time of shooting and can be from what I understand be modified or adjusted within Silkipix Digital Camera Utility 5. Possibly through reverse engineering the algorithm use by the camera to separate the original 4 images and reapply the algorithm. Any time I used the process with DCU 5 the image on the screen would refresh in segments as the program separated the layers of the blended images, made the corrections and reintegrated the blended images back together.
In my mind this would make sense considering the possibility that Silkipix probably wrote the code that blends and creates the Pixel Shift images within the K70 so they would be able to produce the code to reverse engineer the process. Another indicator of this possibility is the size of the file created when using Pixel Shift, the average non Pixel shift PEF Raw file is 20 to 23 MB while a Pixel Shift PEF Raw file is over 100 MB or 4 times as large
