Cleaning M10 DNG images

Those of you that have read the M10 raw file analysis thread will know that M10 DNGs have more baggage in them that is typically the case for a Leica DNG. I've put together a little app to clean them up, called DNG Cleaner (Mac only for the moment). For M10 DNGs this will remove:

  • The full size image preview - that will save about 3MB
  • The various Lightroom/Photoshop adjustments embedded in the XMP portion of the DNG - ISO dependent noise reduction settings, lens profiles, etc

DNG cleaner will also optionally remove opcodes, and apply lossless compression. This isn't relevant to the M10, but in many other Leica cameras, e.g., the Q, the SL, etc, opcodes are used for lens correction. DNG Cleaner is what Sean Reid used to remove opcodes for his SL 50 review, which some of you will have seen.

 

As ever, back up your files before using any app that is designed to modify them.
