reading M10-D RAW/DNG files with linux/python/gimp

The only imaginable reason seems to be the DNG Copyright which is not open source. Internally DNG-files are converted to tiff anyway. Sometimes it is more convenient to have the conversion done from CLI rather than opening a GUI like RawTherapee, since storing files and processing may be different steps.

i fully agree - RawTherapee's RawEditorCli does exactly that.  i imagine that other open-source RAW converters also can be called via CLI.  obviously it's pretty elegant too to implement a pure python solution if one prefers so.

I use Darktable to develop my dng files. Very convenient and easy to use. Once you have your own profile, DNG Development is very fast and easy. There is darktable-cli as well.

Reading this thread, and failing to understand much, ( actually all ), of the technical and coding as well as trying to comprehend why the hell anyone would go to such lengths to "develop" a digital negative as fenykepesz and others are doing when out of the box solutions work just fine as far as I can tell I remembered that this was exactly what I used to do when souping TriX trying all kinds of chemical concoctions and variants to come to a "look" that would please me when ID11 and D76 worked just fine.......It just goes to show that "what goes around does indeed come around"

Good luck guys!

The dng file is pure raw data from the sensor.

 

I would suggest this video (sorry in german) about RAW data. It is not RAW direct from the sensor, it is processed data and a lot of tweaking is done.

you know, petermullett, i understand you exactly what you mean with 'souping' chemicals and doing darkroom tricks etc.  we all did that to some extent, though in my case it was with Ilford products.  i fully agree that in first line it's the picture content that matters while some of the processing steps and explanations behind them include elements of wishful thinking.

now, in terms of developing digital negatives, i do actually quite some 'digital negative' work as i have scanned all my old negatives, mostly b&w, and convert them nowadays slowly into positives, and where it's worth it i do some more extensive retoucher. 

but in terms of my workflow today, using raw DNG files from the  m10d, i needed to set up something that was compatible with my lnx computing environment which is not entirely w10 or osX.  so, this setup in it itself is nothing special, as folks with LR, PS and alike may likely do very similar procedures as i do with RawTherapee/Gimp.  Darktable would be a good choice too, as per supertomi.  so, ultimately we are all on the same page i believe...
