Samsung SM-G970F dng files: wrong colors raw

@ggbutcher
thank you
It looks logical that the software does not support the camera.
I thought so too at first. but as I already wrote another software is much older, and also can not have camera support ā€¦
and not only in that photo where the sky is gray, not pink,
but also regarding the profile editor, the RT does not understand the profiles made by it, and this is also a problem, because I can not even manually correct them.

anyway, I just want to get an off answer from the developers, if itā€™s really problem only in camera support, or not, and help them to more speedy implementation of it if I can.
regards

Youā€™re looking at this the wrong way. Developers add support when users provide the sample images necessary to do so or when a user requests it.

it is good if it like this! ill do provide of any specific samples if i can.
but i cant know problem from startā€¦

The metadata tags your camera as ā€œSM-G970Fā€. I Googled it, and it appears to be a Samsung S10 cellphone, no? Thatā€™s somewhat new territory for us old folkā€¦ :smile:

Nominally, what it takes to insert minimal camera support is to shoot an image of a color target and use it to produces a camera profile. My granddaughter has a S10, next time she visits in the daylight, I can make such an image. Assuming the US version has the same sensorā€¦

As cellphones incorporate the software to shoot raw, thisā€™ll be new territory for supportā€¦

it good news but it looks like snapdragon and exynos versions have different sensors, and US have snap, i think.

also its no new territory is already 5 years here :slight_smile:

@dssdd I will answer later in the evening. Supper time now :slight_smile:

After reading this I loaded both examples into Darktable for an analysis of the material.

Im my opinion it is not an issue of the camera support, it is an issue of the massively overexposed image.

The squares in the upper image part represent overexposed areas within the RAW data. Which means the light was so bright that the sensor data is corrupt.
Programs like Rawtherapee or others can only try to ā€˜imagineā€™ what data could have been there.

Resulting problems often are flawed white balances:

  • To set the white balance I first tool a sample from the ā€˜greyā€™ sky in the top-right. The result is a greenish image, which you can see in the left half of the screenshot
  • On the right side you see the white balance taken from a sample from the stonewall in the center (where the small rectangle is). Here the white balance looks good.

What works different in various programmes are the algorithms for highlight reconstructions for overexposed areas.
Sometimes they look good, sometimes they create weird colors.

My recommendation: Take a properly exposed photo and load it into Rawtherapee and Photoshop. I donā€™t think that there will be bigger problems.

Edit: For highlight reconstruction programs look for colors around the overexposed areas and try to move them into them. Could be that some details like these fine lines are lost. In these areas it is not easy to detect valid data.

Iā€™m guessing that this, plus the fact that the Galaxy S10 has three back-facing cameras (plus 2 front facing, although itā€™s hard to imagine taking the selfie cameras seriously), will make things difficult unless each camera/sensor combination can be identified.

Cameras:

  • 12 Megapixel f/1.5-2.4 variable aperture camera with 960 FPS slow-mo, 4k, etc
  • 12 MP f/2.4 telephoto zoom lens
  • 16 MP super-wide angle camera.

is true, but not affect our case, bc only one camera can shoot in raw in all devicesā€¦
and different models have different code name SM-G9*** but only two mods.

@heckflosse
its ok, im wait, but please just dont forget about me compleatly :slight_smile:

Thanks, good infoā€¦I may be buying a S10+ soon.

@heckflosse

it looks like 5 supper times gone :cry:
can you light something?

Not yet. I would have done.

Too many irons in the fire, almost forgot to follow up: turns out she doesnā€™t have a S10.

looks like it was compleatly forgottenā€¦
@heckflosse
please say atleast how it going or not? when comes or not comes?

you see, i looked not wrong wayā€¦
no support, no answer about plans, no timemap, soon 2 months gone and nothing.

Please donā€™t make your prejudice about open source projects into a self-fulfilling prophecy. You need to adjust your expectations for open source projects.

  1. There are usually less than a handful of active developers who need to divide their time over many different issues with the software.
  2. Itā€™s entirely up to the developers to decide if they want to work with timelines and so forth, or just cherry-pick issues along the way. You might think this means a project is badly organised, but thatā€™s the reality whenever something is done entirely by volunteers.
  3. Donā€™t assume your issue needs priority, simply because it affects you.
  4. Keep a constructive dialogue when the developers arenā€™t as quick as you would like, donā€™t get defensive.
  5. If the information necessary for a fix to your issue is actually not yet provided, not a lot can be done. @Morgan_Hardwood and @heckflosse, what is still needed?

The simple reality is that adding camera support is usually a bit of a tedious thing to doā€¦

hey bro, with all respect, but what the hell self-fulfilling prophecy???
from the start i ask only for easy and short answer that clear situation -
ā€œyes, we will take about for X-weeksā€
or
ā€œno, we will not take, until there is no possibility and we do not see it in the next six months, later - perhaps.ā€
like that, itā€™s so simple and itā€™s damn banal politeness.
I do NOT command ā€œquickly add urgently, bastards,ā€ NO.
Iā€™m not aware of your situation, right? simple explanation of intentions, and approximate timelines ā€¦
why make me a villain?

This link was needed from the beginning!
we would not have lost almost 2 months ā€¦ then you answered me about the color target, I thought that it was necessary to have it ā€¦

So I took pictures, because the article does not contain words about white balance, I left the auto.
I hope I did everything right, shoot all in 1 sec, for all available modes of ISO, for each available aperture (there are only 2).
but there is one photo exception.
The fact is that the stock camera in manual mode has a restriction of only ISO800 when the module itself and third-party applications can choose FREE value up to ISO1250! but at the same time 1s, can only be selected in the stock application, and the rest are limited to 1/10.
so please let me know if i do something wrong or need something else, i do again.

ps i have error upload for Filebin, so i put files here GalaxyS10.7z (268.6 KB)
