    Interesting article with examples of K-1 pixel shift

    Hello All,
    This article shows some nice examples of pixel shift images from the K-1

    http://redredphoto.com/blog/equipmen...w-pixel-shift/

    Note that you aren't restricted to the post processing software discussed in the article, you can use 'dcrawps' to export a 16 bit tiff from the 4 image raw, and post process that in your software of choice, and a nice bonus is that dcrawps will report if your pixel shift images have any artefacts due to camera or subject movement.

    Cheers,
    Terry

    Not sure I would use this feature. Seems only the Pentax software processes correctly.

    No, pixel shift images can be processed by dcrawps, a fork of David Coffin's dcraw software, and freely available, just search for dcrawps.
    It is command line, and available as binary for Win (and OSX I think) and source code as well...easily built in Linux and OSX.
    It will process the 4 raw images and allow output of a 16 bit tiff.
    One of it's nice features is that it will tell you if it finds any artefacts resulting from movement and will make corrections.
    Movement artefacts are found by comparing the two raws that were aligned on the green filter, a technique which I think Pentax adopted with the movement correct in the K-1.

    Cheers,
    Terry
