Converting RAW-Files from Modified Color Cameras to Monochrome DNG

For those who have converted a color camera to a monochrome sensor (see for example the Nikon D850 Monochrome by MaxMax.com), it’s important to process the image properly.

That is, the raw converter has no means to know that the raw file is in fact a monochrome file instead of a color one. If the capture is processed as a color file, inferior results with artifacts will occur, since the raw converter will use Bayer matrix demosaicing on a the monochrome pixels.

Enter LibRaw Monochrome2DNG, which takes the NEF or ARW or other raw format and turns it into a true monochrome raw file, in DNG format. It operates on whole folders or folder hierarchies and is highly efficient in using CPU cores—fast and easy.

Diglloyd Making Sharp Images articulates years of best practices and how-to, painstakingly learned over a decade of camera and lens evaluation.

Save yourself those years of trial and error by jump-starting your photographic technical execution when making the image. The best lens or camera is handicapped if the photographer fails to master perfect shot discipline. High-resolution digital cameras are unforgiving of errors, at least if one wants the best possible results.

  • Eases into photographic challenges with an introductory section.
  • Covers aspects of digital sensor technology that relate to getting the best image quality.
  • Technique section discusses every aspect of making a sharp image handheld or on a tripod.
  • Depth of field and how to bypass depth of field limitations via focus stacking.
  • Optical aberrations: what they are, what they look like, and what to do about them.
  • MTF, field curvature, focus shift: insight into the limitations of lab tests and why imaging performance is far more complex than it appears.
  • Optical aberrations: what they are, what they look like, and what to do about them.
  • How to test a lens for a “bad sample”.
