Technically imagemagick could do a direct conversion .dng -> .jpg. The "but" is that dcraw is doing more than just a format conversion, it is using some magic options (chosen by Martijn) to try make the picture look better as per the comments in the postprocess script. dcraw cannot output .jpg though. But again the megapixels choice to use imagemagick to do the conversion to .jpg also allows the chance to get imagemagick to try sharpen things.

Or you could cut out most of the (megapixels) postprocessing and use a package like RawTherapee to process your images.

The fundamental limitation though is the inexpensive sensors chosen by Pine64 are pretty much point and click cheapos and so no amount of postprocessing can turn me into David Bailey! Then again, even with slightly expensive kit I struggle to get stuff in focus so having the PinePhone for quick snaps is fine by me.

I saw that there was other processing going on to fix up the images. Still, for me the Pinephone camera would only be for occasional quick snaps, and quick processing would be more important to me than improving the image in post. (If I want quality photos I use a real camera. Smile)

Now that I have the local script in place I'll play around with it. Might even be best to just let it save the dng images and run my own batch conversion afterwards. The phone is running on the eMMC but my data directories are symlinked to a 256GB SD card so the large size of the images isn't that much of a problem.

Actually just tried to play a bit more myself and seems this is complete codswallop! imagemagick delegates the raw processing to ufraw, which in turn subcontracts to dcraw! So using dcraw in the first place is very sensible by megapixels/Martijn Smile 

Yeah batch processing later would certainly keep the megapixels frontend looking more ready for action!

FYI, megapixels was finally upgraded to 0.16 (which includes the fix) in Mobian unstable on Thursday.
