What's new:

In the time since RawDigger 1.2 was released, a certain number of requests from our users has piled up, which we have now fulfilled.

This has caused changes in the menu, Preferences, and user interface; thus, the increase in the sub-version number from 1.2 to 1.3.

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.

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.
