Is the 48 mp camera real or fake? - Xiaomi Redmi Note 7 Pro Questions & Answers

Hi everyone. I'd like to know if anybody could get a 48 mp dng file from this phone. It is strange that raw file is only 12 mp. The quality of the 48 mp jpeg image is poor and seems rather an interpolated from 12 mp. How is possible to get a raw file smaller (12mp) than the original (48mp) ? And many camera aps won't give the jpeg 48 mp option but only the 12 mp. Comparing an original jpeg 40 mp from p20 pro with the one that this phone offers, the difference is tremendous on details and structure. Thanks for reading.

non-pro --> fake
pro --> real

For what reason then, it won't give a 48 mp dng file? And also you cannot have from 48mp jpeg the option 16:9 ? If it was the stock camera limitation, why then, all other camera apps behave the same way?
Speaking always for pro model.

I did not quite understand what you were saying. The 48MP shots are "real" as Xiaomi claims. For non-stock camera apps, just make sure you have Camera2API option available and enabled to enable 48MP mode. For instance, I enabled the same in Open Camera, and I had the capability to shoot "48MP" in RAW dng format.
And I kinda sorta get what you are trying to say, but I do not know enough about the topic to comment.
Here is one shot from RN7Pro with Open Camera app with Camera2API enabled, saved in jpeg and raw. One is the standard jpeg with resolution 8000 x 6000‬ and 6MB in size, the other is the dng of the same shot with resolution 3984 x 2984 (11.9 MP) as reported by Photoshop with a file size of 22.9 MB:

DNG: https://drive.google.com/file/d/1Y6Xrez8sjFBP3HWI1__HchVtZ7unBTRr/view?usp=sharing
If you plan to compare the RN7 Pro, which costs as much as an early mid-range device, against the Huawei P20 Pro, which is top tier flagship from last year, then you will definitely be disappointed. One phone costs a couple of times the other. So that comparison does not make sense to me.

For a moment I was happy to hear that you were able to shoot 48 mp in raw dng format with open camera, but then I saw the dng file you posted was only 12 mp (a little less perhaps). So, unfortunately, I still am suspicious about what xiaomi claims for the camera since it is not possible to get 48 mp dng file with any app. The size of such a file should be about 45 mb. The quality of images of not 7 pro is excellent but the details are of 12 mp level. I posted an image from mi note 2 (21mp camera) where you can see the difference in details. I wonder if I get such an image from an older phone what should I expect with a newer with the double size of mp in the sensor. I'm afraid we have to do with a xiaomi's trick ......
Ps. Now I see that system made my image much smaller. 243 kb instead of 12 mb (original). you v\cannot get conclusions this way.. sorry.

I had the idea to post a crop of the original image. Take a look.

Ok, I'll explain.
It's a Quad Bayer sensor, what typically results in lack of raw output availability in case of the full res. That's due to the fact that OEMs assume no app would be able to process non-standard array, else they would have to process it on their own, through utilizing stacking (superres?) or simple remosaic. The latter would result in artifacts or loss of quality.
Because of that, all available raw streams come from binning (pixel "merging").
About the quality tho, it's just a Xiaomi thing. All you can currently do is disable the edge mode and denoising in Open Camera. Then your results might get more detailed, possibly at the cost of color fringing. At least, that's the case with Mi 9.
But about RN7 non-Pro, uhh. It has S5KGM1, which doesn't even support any kind of 48 MP mode, so the 48 MP images from RN7, Oppo F11 Pro, Vivo V15 Pro end up being a placebo.

Sorry that I saw your answer after I started a new thread with the same subject. Thanks for all your info. Still I wonder, why we cannot get a 48mp DNG file with any app, like for example on p20 pro that has the same quad bayer technology. And how is possible to get a 12 mp rawfile, from a 48 mp sensor? With p20 pro we can choose between 40 mp dng or 10 mp jpeg with binning technology. Why this is impossible with RN7pro ?

Another question that I have is that: If all available raw streams come from binning, then the 48mp jpeg from where it comes?

Sensor mode itself is a raw stream (typically 10 bit), but drivers are constructed in a way that filters out any quad bayer raw access from third party apps. The 48 MP JPEGs come from processing applied on it by the camera stack.
For further data, you can look on Camera2Test and most importantly, "dumpsys media.camera" command. "sensormode" is the keyword you're looking for in case of the latter. Then you'll get a 8000x6000 mode listed with a third number, which means the framerate, probably around 24 fps.
And anyyyway, disable edge mode and denoising in Open Camera if you want to see something about IMX586 with bare eyes.

Thanks, I can see what you mean. It's a pity thow, that there is no a 48mp dng file which, in bright light might be very interesting , offering hight level of details.... I guess that with 1,75 f and binning, xiaomi's goal is a brighter image in the shortest shooting time. This kind of images are very good for internet media use, but in a big screen they are worse than images from older phones .

Well, as said before, try setting edge mode off with denoising off in Open Camera, with Camera2 mode enabled and 48 MP resolution selected. You'll notice a rather good difference, but be aware of the color artifacts. BTW, the best 48 MP outputs available yet are coming from Honor View 20. Maybe Google will outperform that on Pixel 4, but it's just a guess.

Is there a RAW capture mode?

GSMArena's review just came out and they state that there is no option to capture raw files with this device.
That's sound very odd. Can anyone confirm this?
Thanks.
It's not true there is a option for pro mode which captures in raw
Their article said two things :
There's a Pro mode for those who want more control over the camera. It comes with adjustment sliders for white balance, exposure compensation, ISO, shutter speed, and focus. RAW capture is available as well, although HTC claims the majority of consumers don't use this feature.

So, in camera PRO mode, RAW mode is here
Then,
We can almost overlook the absence of RAW, but it is signifficantly harder to swallow the fac that HTC's camera app does not offer the ability to change the frame rates that video is recorded in

So this part is only about taking a video in RAW mode. This mode principally exists fir DSLR cameras, and if I don't mae mistake, never have been introduced on smartphones
The only regret I have with the camera PRO mode is that the U11 only takes RAW+JPG photo. You can't take RAW pictures only so .... we have to take care at the storage

Thanks for the clarification! Glad that raw capture is available on this phone.

48 megapixel RAW Support

Is anyone aware of a mod that would enable us to save to raw format with full 48 megapixel resolution? That would be amazing.
It's not a "full" 48mp sensor anyway. The color resolution is 12mp only, so I doubt you will get much better images using 48mp Raw :good: Quote:
"The sensor is characterised by its 48MP resolution and ability for 4:1 pixel binning into 12MP. The actual sensor’s colour filter is a quad-bayer setup, meaning the real chromatic spatial resolution is 12MP anyway, and the 48MP mode is enabled via pre-processing on the sensor itself, really only achieving chromatic spatial resolution equivalent to about ~27MP. OnePlus here does things better than a lot of other vendors; the 48MP simply isn’t available outside of the Pro mode, and I suggest users to just avoid using it at all."
(From Anandtech review, it's very thorough, as ever)

Which photo editors work in full res (27MPx)?

And are they responsive on the Mi note 10?
Lightroom? Any other? What about Snapseed ,does it keep the 27MPix? Thanks!

in snapseed, just make sure you choose "Do not resize" option in export setting.

Unfortunately, that isn't the case for a full 108MP image. 27MP seems to be fine, just a little smaller sometimes, but I think the phone hardware isn't powerful enough to process a 108MP image without reducing the resolution and quality.
Quick update: Photoshop Express retained almost all of the resolution and detail of a 108MP photo. The resolution went from 9024x12032 to 9000x12000. That's a negligible difference.
I prefer Snapseed as an editor (I love the masking and curves), but maybe it's time for me to learn more about the Photoshop Express app.
Thanks!
I researched and Snapseed apparently supports a maximum resolution of 20MPix. So I guess good for slightly cropped images to save original detail
https://support.google.com/snapseed/answer/6202870?hl=en
PS Express is 30,000x30,000 max:

Update: I tried editing a 27.1 MPix sample (I haven't got this phone yet) on Snapseed, PS Express and Lightroom, and LR kept the original 27.1 MPx while both Snapseed and PSX resized to 25 MPx. VSCO also keeps the 27.1 MPx

well, even whatsapp sometimes crashing when i tried to send image from this phone. 108MP is indeed way too big for most of current app design

Open Camera now allows P20 PRO to record video using all lenses

Hi all, you might know this already but I just found out and it seems like absolutely great news for this phone. The latest Open Camera update allows you to record video using every camera on the phone. Even the monochrome one works. No need to have perfect lighting conditions in order for the camera to switch between main and telephoto. You now have a dedicated camera button which lets you select what lens to use. Did you get the chance to try it out? I didn't have any issues yet.
Link please
Here it is:
https://play.google.com/store/apps/details?id=net.sourceforge.opencamera
Is the recording quality improved?
I'm not sure. You do have to option to record with maximum 80Mbps but I I find it hard to tell if that is any different from the 30Mbps standard rate. Video looks crisp and clear, colors are very good, especially if you lock the white balance.
Quality seems not as good.. Also can not use Camera API 2, for high res to get extra control in manual mode.
I'm not sure why you can't use camera2 api. For me it works and I can select iso and exposure during filming. I have a CLT L29.

whats your max resolution for recording video using Camera2 API?
For the 40mp lens and the telephoto lens, I have 3840x2160. The monochrome camera however has a resolution of 3264x1840 for video.
Sorry for necropost, but anyone tried open camera for B&W photos? Does it allow exposure bracketing? Raw or at least png for file saving? I would like to try p20 pro just for that monochrome lens...
You can save RAW with the B&W camera but for some reason the pictures appear purple.

Question Expert Raw 50Mpx RAW

Hello everyone,
Is it possible to tweak, bring 50MPX raw from the S23 Ultra for S22 Ultra? Or even 24Mpx would be great.
Thanks
none ?
I believe you only have two options, or 12 or 100 mpx maybe some additional app from the play store ?
I got an Update yesterday, bringing OneUI 5.1 and Expert RAW and many more features from S23 Ultra to S22 Ultra. Check for Updates maybe

The 3:4,108MP option is not available in Expert RAW.
Choose in the normal camera save raw and then 108MP and you get a jpg and dng file for each photo. Sadly Pro mode is locked at 12MP.
Yes it locks to 12Mpx in Expert Raw, so that's why I asked if someone can tweak it to make 50Mpx possible like S23Ultra, or at least 24Mpx...

"Normal" camera mode does not save any image in DNG. Only Expert RAW and Pro mode does. The phone does not save any images taken using the 3:4, 108MP mode in DNG; only JPG.
