DNG files from an android phone

I got a brand new smartphone, a motorola one ace 5g with android 11. It does DNG files in pro mode.

I just tried it. But in ART, there is no automatch tone curve in the tone curve.

Does anybody has any tip on how to improve the colours and the exposure processing?

In the end, if I process to B&W, itā€™s quite decent (think Canon 40D level), but if I process the image in colour then itā€™s so so. Iā€™m convinced that itā€™s due to the phone itself. This phone is neither the quality of an iphone or a galaxy but I didnā€™t pay these prices either.

Thanks

Share one maybeā€¦ I know my pixel takes DNG that work with automatch if I use the google app but OpenCamera saves a DNG file but i think its really a tiff as it does not work with automatchā€¦

EDit:

You might also find some interesting comments and or tips hereā€¦

Hi,
You can try using the ā€œstandard film curveā€ profile and see if that helps. Otherwise, share a raw as @priort suggested and Iā€™ll take a look.

HTH

I need to put this on pause. Yesterday, after posting this, I did a debian upgrade and lets say it didnā€™t go well.

I will upload the file in a few days.

Thanks

Sorry to hear thatā€¦very frustrating

There is only one thumbnail in the DNG, I think ART canā€™t draw a curve from such a small image. I canā€™t extract anything else with exiftool from a Fairphone3 DNG

The OPā€™r has a Motorola phoneā€¦the Fairphone was just part of a link I shared that touched on a similar topic with some discussion and insight on these filesā€¦ Indeed on my Google pixel the DNG produced by the phone depend on the appā€¦Native app is fine and will work with Art as would a normal DNGā€¦ The oneā€™s that come from open camera are a different beastā€¦ and they donā€™t have an recognized embedded preview whereas the native ones doā€¦despite being half the size of the files coming from Open Cameraā€¦so lots of nuances to consider wrt phone, app used and post processing softwareā€¦

Hereā€™s the imageā€™s link.

This image was produced by a motorola one ace 5g and android 11 with the default photo app in the ā€œpro modeā€ to get the dng.

Thanks

Looks like these images support gain maps so for sure apply flat field correction adjustment and select embeddedā€¦it will take away the strong vignette and improve the lightingā€¦it will look for all intensive purposes like a lens correctionsā€¦

Here is a quick tinker I didā€¦but with no real targeted color work just boosted sat and vibrancy.

Color is pretty subjective with peopleā€¦ I am also not doing this on a very good or calibrated monitor

Nice.

Very interesting on how you processed. Things that surprised me:

  • log tone mapping: the black point. How did you get the: -6.9ev?
  • local contrast (and no extra texture, I always add some texture if I use the local contrast): Why from midpoint to the whites, you kept it to the same level?
  • haze removal: quite aggressive

I like the processing and am trying to learn. This not criticizing in any way, just clarifications on why so I can understand better and do better processing.

Honestly I donā€™t use art other than to experiment. So I was just trying to bump the color. I am sure others will do a much better job. I literally just went through things I knew would add contrast and colorā€¦Dehaze is aggressive in ART. I blend it in lightness blend mode often in DT and I think RT has or had a lightness mode for dehaze if you donā€™t want the big bump in saturationā€¦ I the case of your image I went for the bumpā€¦

I still like your processing. It was interesting.

Thanks

Well thx. just be sure to add that flat field by defaultā€¦the rest is up to you :mask:
