Monochrome2DNG - File Converter for «Monochrome-Converted» Cameras

Almost all digital cameras that are released today are color cameras. Nevertheless, there is demand for BW (Black and White) cameras because of reduced artifacts and higher resolution of resulting images. And many photographers want BW cameras with the same lens mount as their main (color) camera, so that they can use the lenses they already own.

Converting a color camera to BW is done by removing the CFA (Color Filter array). However, during such conversion, the firmware of the camera doesn’t change, and the camera doesn’t know that it’s become monochrome, which leads to several problems, which Monochrome2DNG - a file converter for «monochrome-converted» cameras - is going to address.

DPRSplit (Beta) - File Splitter for Canon 5D Mark IV / Dual Pixel Raw files

Canon 5D Mark IV's sensor has a somewhat unusual pixel arrangement: each pixel is composed of two subpixels. If Dual Pixel RAW mode is enabled in the camera, the resulting CR2 file contains two images, or two frames: one composite, made from reading both subpixels, summed; and the other is made out of one set of subpixels.

In essence, in Dual Pixel Raw mode, the camera records into one file some equivalent of two shots, bracketed by (approximately) 1 EV.

The DPRSplit application is intended to extract this additional frame out of the CR2 taken in Dual Pixel RAW mode, and save it as a DNG. Resulting DNG files can then be opened and processed in (practically) any raw converter featuring DNG support.

SonyPixelShift2DNG (Beta 0.8.4): Convert Sony A7R-III Pixel Shift Mode Shots to DNG

In order to streamline the workflow with the raw shots taken in the new Pixel Shift Multi Shooting mode offered by the new Sony A7R-III camera, 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 SonyPixelShift2DNG application, which converts Sony A7R-III shots taken in Pixel Shift mode to DNG.

The resulting DNG files can later be processed in familiar applications like Adobe Lightroom / Camera Raw, CaptureOne, Iridient Developer, Luminar, and others.
