Just remove the CFA, and your monochrome camera is ready. * Because a color camera differs from a BW camera due to the presence of a color filter array (CFA, Bayer mosaics) over the sensor, converting a color camera to BW looks (theoretically) simple. E-Mail: and a little bit more about CFA removal.
This site feedback form: special section, designated for Monochrome2DNG feedback. This is a beta version, and it’s important to us to know your thoughts and suggestions. V0.9.2: Preferences-Crop Mode: 'hard crop mode' implemented.Ĭhangelog in more details Getting in touch with us V0.9.1: Panasonic RW2 bad pixels filtering camera model change settings. 
V0.9.0: Implemented mosaic suppression for non-uniform grid patterns (use Preferences - Mosaic Suppression - Method B to enable new method) V0.8.6: Panasonic RW2 files: add LensName and LensSerialNumber to EXIF data
#RW2 FILE CONVERTER WINDOWS 10 UPDATE#
V0.8.5: Just version update to extend beta expiration time to Sept 1, 2018 V0.8.4: Better handling of file names in non-default system locale/language. V0.8.3: Fixed font size auto-selection on 1st run. V0.8.2: DefaultCrop* tags are written in DNG even if crop margins are not set. V0.8.1: Preferences - Override black level added.
User Manual: Monochrome2DNG-Manual-ENG.pdf. On the right, the same RAW data, but ACR has read it as monochrome. On the left, it’s been processing like a color file (ACR will do this “by default”). The image below shows the same shot taken with a Canon 6D (converted to a monochrome camera) and processed by Adobe Camera RAW 10.2. The first problem leads to most RAW processing programs continuing to think that they’re processing a color file and, accordingly, preform demosaicking, which leads to resolution decreases, moiré, and aliasing. In the case of a camera converted to monochrome, equally exposed pixels that originally, before conversion, belonged to different channels, receive different RAW data numbers. In many cameras, sensor data is processed differently for different color channels before the RAW is recorded (for example, White Balance preconditioning for Nikon: the values of the red and blue pixels are multiplied by small coefficient). The monochrome file recorded by the camera cannot be told apart from a color shot without a complete analysis of of the RAW data – all of the metadata corresponds to the color file. 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 the following: This, in turn, leads to higher resolution and a decrease in the number of processing artefacts (see the Bayer Moiré article), which is, essentially, why people perform the conversions of color cameras to monochrome. Since a color camera differs from a BW camera due to the existence of color filter array (CFA, Bayer mosaics) over the sensor, converting a color camera to BW is done by removing the CFA*.Īfter the CFA is removed, the demosaicking process that is done during RAW file processing becomes unnecessary. Nevertheless, there is demand for BW (Black and White) cameras (for reasons explained in detail below), 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. Several Leica and PhaseOne models are rare exceptions, but these cameras are even more of a niche product than the color cameras or digital backs made by those same companies. Almost all digital cameras that are released today are color cameras.
