+Tek Syndicate just published one in video and they're pretty enthusiasts about the results 🙂
A tip about converter software: +Albert Manduca, who shows his experience with RAW editing uses +Adobe Lightroom which is great as it's one of the software that implement all the DNG capabilities I used during profiling.
* Color calibration
* Noise profiling
* Lens vignetting correction and sensor color uniformity
DNG files are the RAW sensor data plus metadata that describe shooting conditions and how to transform what the sensor sees into a corrected image representing colors as they are.
Compared to proprietary RAW formats, DNG is self-describing.
Smartphones' captures require more correction than other cameras due to their physical constrains.
Some converters support DNG but not all its features.
Typically, noise, vignette or color uniformity won't be corrected as expected, color conversion incomplete, exposure compensation not applied so be sure to use a fully fledged RAW editor!
By the way, did anyone made a comparison with a Lumia DNG?

With the 'Save raw image' option enabled I often have camera faults where 'cannot connect to camera' is displayed after taking pictures. The only fix is a reboot.
Great job man! Loving the CM camera on my 1+1. The new RAW image has been working great!
+Dan Brookes well that's not good, I encourage you to report the issue to CM and file a new bug if it's not already existing.
+François Simond Unfortunately I'm on the CM Nightlies, but a friend with stock 11s had the same issue. I'll file a bug report.
Do you think we'll see RAW imaging in stock android anytime soon?
+Jasper Linford yes RAW capability comes with Android L Camera2 API.
However it doesn't guarantee that each manufacturer will implement it, so we'll see.
Also I evaluated the DNG implementation in current preview on Nexus 5 and the profiling is rather poor, but if you're interested in that make sure to continue following my posts 😉
+Jasper Linford RAW capture is part of the new camera APIs in Lollipop. There's already a RAW camera app in development for the Nexus 5.
+Dan Brookes +François Simond from my experience, these force closes only appear when in long exposure mode in combination with raw enabled. +François Simond did you test this scenario when you were implementing the feature?
+Marian M I didn't worked on camera low level layers or CM application code, only the DNG color science and profiling.
Yes +Marian M, that seems to be the situation where it happens a lot.
+François Simond so you do not have a oneplus one yourself?
+Viljo Viitanen I still have a non final prototype that can't run firmwares built for several months.
Working on my own projects now!
Apples and oranges: Having a lowly G2 I use Mi2cam for DNG photos. Don't know if it's the implementation or my lack if skillz but I don't get results from lightroom worth the added steps. Noise and color correction is way off.
However Photoshop Express does DNG on the phone, can give impressive results and is much easier.
+Franklyn Pearson I have the same setup. I get pretty good results from Photoshop Express on the phone. I've had a decent experience in Lightroom as well.
+Franklyn Pearson when I checked Mi2cam, about 2 months ago on the OnePlus, the DNG had only basic color conversion, no correction for vignetting and color cast or other advanced profiling.
It prevents reaching high quality results even for skilled photographers.
That's why I was anxious to see reviews on this work from experts used to play with professional equipment like guys at +Tek Syndicate!
Wow! That is freaking awseome!!! +Tek Syndicate
+François Simond does Photoshop Express use all the DNG features that you added? My results are quite satisfying, but I could be missing those important corrections.
How does Rawtherapee compare?
Has anyone used this: https://play.google.com/store/apps/details?id=com.tssystems.photomate2
+Jason Crabtree last time I checked it was not implementing the required DNG correction and calibration features I describe, so expect poor results.
+François Simond are there any Android apps that you would recommend?
+Dan Brookes Rawtherapee has a custom, different implementation of the color calibration algorithms, lacks noise, vignetting, color cast support.
Some of that can be compensated manually, some not.
It's brilliant software but lacks dearly in standard DNG features support: expect to spend vast amount of time for problematic results.
+Jeffrey Kovács Yes Photoshop express implements all the DNG features used (you may verify about Luma noise reduction capability tho), results are good!
Thanks +François Simond
Thanks for all the information +François Simond
+Jason Crabtree for now I recommend Photoshop express, definitely.
I just wish it was assuming its own capabilities and would allow to open DNG files directly without file browser intent shenanigans.
+Jeffrey Kovács about Photoshop express, note that results will vary with the quality of the DNG profiling implemented in the camera application.
You won't get the corrections required with Mi2raw until they get implemented by the app author, but results will be good with CM camera app (essentially the same as Lightroom or Photoshop on dekstop)
So how do you get Photoshop Express to open the dng files ?
+Dan Brookes for now I use FX File Explorer, open the file as image/* and Photoshop Express pops-up as accepting application.
+Dan Brookes They need to be "opened as image" in a file browser such as ES File Explorer.
Got it, thanks chaps. Had been trying to do it CM File Manager :-/
+François Simond is there any reason why the camera software on phone is unable to produce same level quality as DNG + manual post processing?
Not intelligent enough post processing algorithms?
+Archish R.S. there is two parameters:
– JPEG output is tuned for a specific look and intent. It doesn't mean it has to be low quality, but very strong noise reduction + overdone sharpening and others enhancements + high contrast and saturation can be what some people want, and it will look like crap for some others.
– manual post processing allows to correct for white balance and exposure compensation, which are usually determined by automatisms that can't be always right .
It also allows to add an artistic intent that's either better or worse depending on each viewer preferences 😉
It sure is a great feature to have. But I think its very important for the camera software and firmware to do good processing too. Many people just shoot in Auto or HDR modes. I preordered 1+1 and hope its better then my current N5, especially in lower indoors lightning.
