Shooting dng pictures on mobile phones (Samsung Galaxy S6 and a few others)

Since I haven't had any time this year to do any photography or video work, and not to mention that my phone is with me everywhere I go, I've found a few apps that enable the capture of raw (dng format) pictures on a few of the Android devices with android 5.1 or higher (requires the camera2 api).

One of these is a free app called FreeDcam, found at https://github.com/troop/FreeDcam. There are a few more but most of them cost a few dollars. Unfortunately, the Galaxy S6 I have doesn't yet have complete support for dng capture, so while the app is able to take dng's and view them, the default gallery doesn't recognize them, thus requiring another app like Lightroom or Photoshop to edit them.

Quality is another issue. The lenses on mobiles don't hold a candle to our wonderful L series or vintage primes, but fortunately they improve with every generation of phones. In lowlight, the shutter slows down to 1/10, which can be pretty annoying if you don't have image stabilization on. The Galaxy S6/Edge received pretty great scores on dxomark, so not all hope is lost.

Editing is straightforward, I've only tried a few dng's in the Photoshop mobile app but I felt like the images had a good amount of image information. Adjusting highlights, shadows and exposure responded very well, and the sharpening/NR adjustments were decent as well. I'll try to upload a few dng's if anyone is interested.

Maybe in the coming years, especially with mobile processors and cameras improving every year, we'll have raw video capabilities in the palm of our hands. It may even be possible now, depending on each phone's ability to dump raw data to memory quickly enough to give a decent resolution.

Thoughts or experiences?

This sounds interesting, are you aware if any counterpart is available for Apple devices?

Take a look at the Nokia 925 and the models above

I think the 925 is the one that has 40 MegaPixels and another model has 50+ MP, all RAW DNG.

all above 925 are atleast 20 Megapixels with supreme lowlight capture.

Oh and as a bonus, built in Carl Zeiss glass! There really are no other phone Cameras on the market comparable to the Nokia

I only have the 620 or something now which is crap. As a replacement for my beloved 920

I had the 920 with 8 MegaP camera, but drinking and taking a walk down at the harbour lead to some stupid stuff and now my phone is sleeping with the fishes.
The 920 doesn't have RAW though. But Carl Zeiss Lens and really sharp and nice colour rendition (FOR A PHONE)

I have to correct a little, its not the 925 that has 40 MP, its the 1020. A friend of mine has it, and I can ask for some DNG's if you would like to take a look. The 1020 is a couple of years old though, but it has quite a large sensor. I've seen some of the pictures he has taken with the phone and it looks like DSLR stuff.

Another friend of mine told me he had recently purchased the 950 and he said it was incredible how he could take pictures at night and "..see everything..." as he put it.

Doesn't say in the spec sheet I found, but I read another place it that the 950 plays h265 files...

But I am not a Nokia Phone Fanboy, the higher models are Lightning fast with the processors and everything, the responsiveness is instant. But the App support is so slim, that I can't really recommend it as a smartphone to anyone. I personally never had any app installed on any of my smartphones, so for me its okey.. But I can see with the Iphones and their countless Camera Apps that they probably are better in the end.

I buy phones for their cameras and I am looking in to buying the 950 to have a good camera on me at all times.

RE: EDIT: Oh and I want to add that the way Nokia labels their models makes ((((NO)))) logical sense

I haven't heard of any apps for iPhone that support raw images; there was an app last year claiming to capture "raw" 4k video on the iphone 5 or 6, but it was only mjepg format due to the fact that the app functioned by taking 24 full res jpeg's per second.

Funny that I posted this thread today. They released an update for the Lightroom app and added a camera option, which also takes dng's. I plan on taking a few dng and jpeg samples for comparison, I'll upload those so we can see if dng format on a cell phone camera is really worth it. A full size jpeg on the Galaxy S6 is between 3-5 MB, whereas a full size dng is roughly 30 MB.

Thanks g3gg0!

Very impressive! First time I get to play with WP DNG.

That was actually not a bad file. Tried some fast settings in acr but it held up quite well.

I found this post searching for information about S6 DNG for a post I wrote this week about shooting in RAW with the Samsung S6.

The post is in Spanish but for those who are still interested in DNG on mobile pones you can find a download list at the bottom.

I'll upload more DNG samples next week.
