In order to streamline the workflow with the raw shots taken in the new Pixel Shift Multi Shooting mode offered by the Pentax K1(-II)/K3-II/KP and Sony A1/A7R-III/-IV/-V/C-R cameras, and provide a way to use popular RAW converters (Adobe Camera Raw/Lightroom, Capture One, and some others) for processing these shots, we’ve developed the PixelShift2DNG application, which converts Sony and Pentax shots taken in Pixel Shift mode to DNG, supported by most (but not all) RAW converters.
PixelShift2DNG performs the two following tasks:
The resulting DNG files can later be processed in familiar applications like Adobe Lightroom and Camera Raw, CaptureOne, Iridient Developer, Luminar, and others.
We've decided to keep PixelShift2DNG as a FREE application.
Download LinksMac users: if you have the previous, Sony-only, version of the application named SonyPixelShift2DNG installed, it will not be removed automatically upon the install of the current version. Please drag SonyPixelShift2DNG to Trash to remove it manually.
High memory usage warning, suggest single worker mode warning: will occur only if estimated memory usage is greater than 60% of installed RAM.
New option: Preferences - Mark output files as locked(Mac)/read-only(Windows)
For a detailed information on how to install and use PixelShift2DNG application please download and read the manual: PixelShift2DNG-Manual-ENG.pdf (the same manual comes with every download of this application and available via PDF Manual button in program main screen bottom button row)
System RequirementsPlease send us feedback regarding this application in our forum or using separate feedback page section.
If you have files that the PixelShift2DNG isn't working well with, please share them with us via Dropbox/Google Drive/WeTransfer and send a link to ps2dng-feedback@libraw.com
Why to Use Sony Pixel Shift Multi Shooting Mode and Our PixelShift2DNGThe new Sony A7R-III has a new mode in it, the Pixel Shift Multi Shooting, in which the camera takes 4 consecutive shots applying a one-pixel shift between the shots. With ordinary RAW files taken with a regular Bayer sensor, only one of the four RGBG color channels is sampled in each pixel location. To guess the unknown color data, we need to preform demosaicking. However, by performing one-pixel shifts of the sensor during the shoot, we can sample information about all four color channels at each pixel location. Thus, we don’t need to demosaic during the conversion anymore, which decreases moiré, improves resolution, and we have an option to average the green channels for every location, improving the dynamic range in the combined channel by approximately half a stop (obviously, one can only shoot static scenes in such a mode).
The workflow for processing files taken it Pixel Shift Multi Shooting mode suggested by the manufacturer (Sony) is as follows: combine four ARW files into one ARQ file using the Sony Imaging Edge Viewer application and process the resulting ARQ file in the Sony Editor.
Aside from Sony programs, ARQ files are supported by beta versions of RawTherapee, RawDigger and FastRawViewer (this list may be incomplete). However, it isn’t supported by some very popular RAW conversion applications like Adobe Camera Raw/Lightroom, Capture One,…
So, now we offer PixelShift2DNG, which allows to analyze Sony A7R-III shots, separating Pixel Shift groups (4 ARW files) and ARQ files, and convert them to DNG.
* There is no 32-bit version right now: to work, the program needs 700+MB of free RAM, which is unlikely on a 32-bit system.
