The concept is pretty simple: the camera takes four pictures shifting the sensor 1 px in all directions so it can have an RGB triplet of information for every pixel to avoid the need to invent the values during the dmosaicing of the Bayer pattern as normally happens.

I will have to realize a series of still life of relatively small objects and I was wondering if the use of the Pixel Shift technology of my Pentax K1 MkII was worth or not. Using it means to have a much longer and complex workflow and the need to use continuous lights instead of flash, so the increase in quality must be balanced with the increase of time to realize the photographs.

Sadly most of the software are not capable to manage properly the Pixel Shift feature so often it means to have to change the entire workflow to get the best quality out of it.

In the video I go in detail in what I found in the experiment.

Here you can download the original RAW files in DNG so you can test yourself.

If you find an easy way to post-process the RAW files made with Pixelshift, let me know!
