Guys,
I've started a multi-part article series discussing how the Note4's camera should be used (and how it compares to other high-end phones, cameraphones or even standalone cameras).
The first two parts in the series have already been published:
Part I: http://www.dpreview.com/forums/thread/3781966
Part II: http://www.dpreview.com/forums/thread/3782300
This series will be of particular interest to Snapdragon 805 users. Exynos users, at the moment, will find the series less interesting, as third-party apps, currently, can't access the (almost) non-processed image stream and they, consequently, can't export non-overprocessed images.
EDIT (2015/01/17): Part III is published on HDR: http://www.dpreview.com/forums/thread/3782850
EDIT (2015/01/24): a brand new writeup is here at XDA; you should start with it instead of the previous ones: http://forum.xda-developers.com/note-4/general/shooting-light-best-image-quality-note-4-t3012008
Great. Thank you

So which app we must use for normal photos ?
How to manually change shutter speed to 1/8s in Snap Camera HDR app? Thx

Basically, if you have an Exynos device, the stock Camera app unless
- you're absolutely sure you don't need shutter speeds under 1/30s (the restriction of many apps, incl. FV-5) and
- you do need the on-screen controls of that app.
Otherwise, the image quality will be the same so there's no advantage in using any third-party app for shooting, as opposed to the Snapdragon case.
If you have a Snapdragon device, you can get far-far better image quality out of your camera in both still and video shooting mode because of the lack of noise reduction and oversharpening. Then, using third-party apps like Snap camera HDR is preferable, assuming, of course, you don't need features like dual camera.

I have the s805 model....there are some settings with this camera to set? Or it will be good with the stock one ?

You can't - the pre-Lollipop API doesn't let for directly setting the shutter speed. The device will automatically use 1/8s when there's little light.
You'll need to make sure you do enable the Photo > “Samsung Camera Mode” checkbox; otherwise, it will NOT be able to go under 1/15s, resulting in a complete loss of no less than 1EV. At least on Snapdragons; I couldn't test this on Exynos devices.

Then, if you really want to see in which cases third-party apps can produce significantly better images, you really want to compare my example shots of the stock app to those of, say, Snap camera HDR - see the crops in my article.
Basically, the stock Camera app applies far too much noise reduction and oversharpening, pretty much ruining fine detail and introducing ugly oversharpening halos. Photos produced by third-party apps, incl. Snap camera HDR, are far more natural.
Just writing my HDR article. The first two parts of the new article is already published: http://www.dpreview.com/forums/thread/3782850
Very nice articles. Thanks for doing them.
Is there any way to get rid of the cruddy yellowish look I get on low light photos on my phone? My wife's phone doesn't have this at all, and both of the Note 4s that I have had do. I've been very unimpressed with the low light abilities of this phone, so far. I'd love a solution that doesn't involve sending the phone in to maybe be fixed.

Thanks! Today, I've continued working on the HDR article.
Thanks for your work. I don't know if I understand correctly but the play store version is 6.2.0. Can this version take pictures under 1/15s? Or we still need a test version for this?

Yup, 6.2.0 has just been released. I've tested it; it works flawlessly, at least on Snapdragon:
1/8s is supported
almost-RAW output is supported
Hi there. It's a nice report! However i do have some input
1. The stock camera does do 1/4s in rare occasions , happens for me when I do shots in not-well lit conditions and yet insufficient for camera to engage in night mode.
2. I have no idea if its just me, but night mode does not downsize my photos to 6mpix no matter how dark the scene is. It still stays at 5312x2998. N910G here. Details of photos on poorly lit scenes do not have significantly worse detail for me as compared to well lit ones and file size is in fact larger by a bit. (the room is still not too dark though).
IMO the stock camera does some sort of multi frame noise averaging technique (similar to canon's and sony's "Hand-held Twilight") to reduce noice.

Wow! Haven't ever seen such an image from my European Snap 805 (F) model. Could you post the original to, say, flickr, or, here as an attachment? (Of course, feel free to remove the location info first from the EXIF data.)

It'd, then, exhibit a much higher probability of camera shake / stitching errors. The relative noiseless-ness is because of the very-very strong noise reduction. (Or, maybe, because of the "G" model you have is somewhat different from the European one? I wouldn't think so - after all, both are Snapdragon-based.)

I've tried all of the settings in the phone. Nothing makes the problem go away. Using the same settings as my wife's phone, and there's a huge difference in the quality of indoor pictures between the three phones.
It does take quite nice outdoor pictures.

Could you take low-light images with an LCD computer screen displaying white
- without(!) using f.lux or other tools to decrease the white balance (this is equal to about 7000K) and
- at both a very low brightness level (to "kick in" night mode) and a high one (to avoid night mode)
with both phones? Preferably in "auto" and "incandescent" WB modes on both phones.

Unfortunately, I deleted those photos as it was blurry due to the unexpectedly low shutter speeds or that the picture sucked. I will post if I can reproduce that setting again.
As for the noise averaging mode...
1. It will not cause camera shake/stitching errors even if you hold still. Why? If you were to shake your phone violently, the software is smart enough to abandon image stacking altogether & the final image produced is the result of just 1 picture that has a little fine bit of extra noise reduction maybe.
2.Samsung's night mode is not well documented, unfortunately, despite them having this mode since Galaxy SIII.
However, the answer lies hidden in one of their support page for galaxy S4
http://www.samsung.com/us/support/howtoguide/N0000003/10094/120418/SGH-I337ZBMATT
"Night: Take photos by combining them to get a brighter, clearer photo in low light, without flash."
Now, you may think that perhaps this mode only applies to the S4's night mode, so I did a mini test.
(click on photos to zoom in)
(1)
Image taken with night mode
(2)
Image taken WITHOUT night mode under same conditions (This is done by tricking the camera to first take a photo in bright light,continue holding down the shutter button to engage burst shot, quickly direct phone to subject and wait for phone to adjust to the right exposure)
(3)
Same image from (2), but edited in Lightroom by dragging the luminance noise slider to like 40.(there is little or no chroma noise, so I did not touch that slider)
As you can see, despite their photos taken under the same conditions, (1) is the best as it as less noisy compared to (2) and sharper than (3).If Samsung really did engage in strong noise reduction at night mode, much fine detail would be lost and the photo will look like an oil painting when you pixel-peep. Thus , night mode photos you take will look more like (3) than (1), when (1) is the actual night mode photo in reality.
3. Another good guess that Night mode is actually a multi frame mode is that, all night mode's photos have their EXIF data eroded.
(Fun fact, dpreview says iphone 6+ does this too)
"the built-in, stock Camera app may have too strong noise reduction and oversharpening"
IMO, Im sorry but I disagree, too strong noise reduction would mean that photos from the note 4 would be too smooth and would lack any fine detail at all, which from my observations isnt true. Samsung excels in that area. Also, oversharpening is also not the case, oversharpened photos often result in false detail and look contrasty/frosty which is again, not the case to me.
EDIT: oversharpening and noise reduction could be a matter of taste so it could be true for some

Ι think this is how stock camera works then it goes under image-processing from sony(BIONZ or something like that) which removes all this noisy noise ...
I don't think there would be any good solution for this.

The noise will disappear once you shoot. I think it is just how the camera shows stuff, then it gets "fixed" by BIONZ.
Bionz has nothing to do with it.The preview is working on different parameters than the camera,so that you can see what you are shooting in low light.The final shot is looking normal.Bionz kicks in after that.It applies the"fix" on the image and it is being saved in the memory.There is also noise reduction processing which only removes those awful white dots the morons from sony havent fixed(making fun of all their customers).In good lighting conditions custom roms perform better,produce sharper images,better colors,etc.
"The noise will disappear once you shoot."
Yea, but before shoot example in Snapchat it's irritating. In Snapchat it is like it was before.

Hello people! I'm trying to record video with my new OP3T, but when I watch the recording, the video frame size (or field of view I suppose) is smaller than what it looks like when I'm shooting. I mean the video resolution is still 1920x1080, but things at the edges of the screen are now out of view. I'm using 1920x1080 @30 FPS, stock camera app, Android 7.0. Same thing happens with other resolutions and FPS settings, and with OpenCamera app for example. But it does not happen when taking pictures, and even when I take a static shot WHILE shooting video, that picture comes out fine.
Is this a known issue? How could I solve this? Is there any modification that could help?

It seems so, yeah. Do you know if this sort of cropping happens during shooting or is it a separate process that's done afterwards? I figured this might be solvable somehow, since you do see the whole picture while you're recording. So it's not a physical limitation of the camera lens or anything.

Noticed that OpenCamera has a function to enable Camera2 API, which fixed the cropping! Also I found that on stock camera app, recording on 4K UHD (3840x2160) doesn't crop the video frame. But it limits to 10 minutes per shot (also workable on OpenCamera due to its restart recording function.)
It's the electronic image stabilisation. It needs to zoom in a little bit to stabilize the video. That's why the 4k isn't cropped, because in 4k, there is only OIS, and not EIS.

Exactly what I thought was the cause of it, thanks for clearing this up ??
Is there any way to disable stabilisation? Different camera app, some mod or something? Even OpenCamera doesn't specifically have a setting for that, but I guess Camera2 API doesn't support EIS or something, which feels like a crutch "solution" at best.

Hi
Will Huawei fix the overexposed soft image quality of the selfie camera on this phone.
I am still on 8.1.0.103 and wondering if its been fixed in one of the newer updates as it is really disappointing
Not sure they think it's broken, it was obviously designed to do this on purpose. I know a lot of people that use beauty mode. It is rather annoying though as it can't be disabled for those that don't want to be enhanced to Ken doll like proportions lol
If you hit the photo mode rather than the default portrait mode for front camera it does help a bit. Definitely better than portrait mode. I do hope that a future update will add more control over the processing, but I won't bank on it.
I've tried many different camera apps, and the overexposure and softening occur as soon as the camera detects a face. Haven't been able to find a solution yet.

im 99% sure it can be disabled with root - its got to be a setting that detects faces.
we;d need someone to go through the source (if they ever release it)
once i root my p20 ill stalk around to try and find a property.
Sorry, i dont have phone yet. But, if you use some other camera application, will it be the same problem?
Its definitely a setting built into the kernel/source code because using another camera app will not override the setting. It only focuses on the subject (face) and blurs out the background which should not be the case
I have rooted P20 pro, and there is a ton of properties and definitions xml files for different modes and effects in odm/camera folder. For example there is something called "casiobeauty" among others But, to mess with those parameters someone has to have knowledge. So, i guess effects can be modified, if there ever will be someone of knowledge and will to do it
You all may want to install CameraMX from PlayStore.
It gives out high resolution and high qualoty images. Selfies taken by it are noticeably sharper than the p20 pro stock camera. Also, there is a slider to adjust exposure for the front cam (something that is missing from the stock). In addition, the app also supports HDR for the selfie cam as well.
You can give it a try...

For the photos below, the washed out one is taken with the front camera native app. The better one is with cameraMX app.
Note: No editing done, same lighting condition, almost the same hand position, same angle.
It is very evident that the native camera app is washed out/overexposed.
Well, the CameraMX photo isnt perfect but for me, it is 80% better than the stock camera.

Hi, I'm pretty much sure it's a software issue as the original photo can look so much better when you edit it. And, you can also use other camera apps
There is a workaround on the overexposed p20 front camera images using the Google Photos Editor App
(I've read it from another XDA thread).
The results are stunning! It's almost as if the photos were taken using an actual Google Pixel front camera! (In my opinion)
I suppose the image enhancement algorithm for the Google Photos app is similar to the image post-processing of Google Pixel phones.
Note: Google Photos is commonly preinstalled along with Gmail, Hangouts, GMaps.
Step 1 - Snap a selfie using the native app
Step 2 - Preview the photo and click the (...) at the bottom right
Step 3 - Click Advanced Edit ---> Select Google Photos
Step 4 - Select the second icon next to the filters menu.
You will find 3 sliders (Light, Color, and Pop)
Step 5 - Slide Pop all the way up, as well as Color.
You may tweak the settings more for Color and Light too!
(There are more options when you expand it)
Step 6 - Click Save.
Find sample photos below:
Just got a P20 Pro and this is seriously my biggest hate with this phone! The rest is great (except my google pay not working) but the front camera makes me look like a ghost on any image!

Yes, I second that.
Whenever I shot a photo from front or back camera, it either doesn't focus at all or takes shaked photos, even when I seem stable with little motion, resulting in bad photo due low shutter speed. Does anyone else experience the same? Is it some hardware issue or it is software? The photos are usually blurry and overexposed. It seems like phone needs a tripod even with 'good light'. It results when I shoot the photo only, because in preview before I take the photo, everything seems focused.
The configuration I see in metadata is usualy 1/20 of shutterspeed with 400 of ISO, AI desabled. Mate 20 lite supports 3200 ISO, so what's the deal? I had Nexus 5X before, and I never experienced such an issue. In low light it was grainy, but focused with 3 years old Nexus 5X, what's with the mate 20 lite?
1. What are the results with the AI mode enabled?
2. Have you tried using the 'Pro' mode where you can adjust the ISO etc?
3. Can you upload full resolution images somewhere? I use imgit.org as it keeps exif data, but whatever works for you.
Hi, having the same "issue", also when trying to capture details (almost Macro photo) camera cant focus correctly....i went from a P9 to the Mate 20 Lite and i'm a little disapointed with the camera quality....hope that the problem it's some sort of configuration....
I always use Gcam.
I use stock app only for extremely lightened scenarios, not even with night mode (with AI stabilizer) because the quality's not the best.

In some dark pictures, the difference is bigger between stock app and gcam app. Try taking a picture with flashlight with both apps in the night and you'll see the difference. (The difference is not only in that case)

Maybe you're right, but i didn't use flash too often. In other hand, maybe have little more details in low light situations but with more noise compared to stock camera app. Even on day shots in shadow area visible noise to me.

In some pictures I take with stock camera (specially in dark situations) there's a blue tone rounding the photo and it's horrible. I prefer to take photos with gcam than Huawei cam. I hope Huawei solve the low quality of the cam in an update.
I had the P20 lite before Mate20 Lite and it took better pictures than Mate20 (even with the higher specifications of the Mate 20)
