Front camera exposure control - Huawei Mate 10 Questions & Answers

The cameras on the Mate 10 are great, but would definitely benefit with some more tweaking. The primary camera performs really well and offers fine tuned control over almost all the variables. I've found that the auto-exposure in low light raises the ISO quite a bit and the picture ends up looking fake, plastic and grainy. This can easily be fixed by under-exposing or by lowering the ISO in manual mode, but only with the primary camera. The front camera always seems to expose for the face. There are no controls to set exposure or focus, and there is no manual mode. Although it performs well in good light, the results are poor in low light and the lack of any control restricts any creative photography. For instance, if I move the camera off my face, it exposes for the background but it doesn't lock. The exposure switches back the instant I reframe the shot. Is there any workaround for controlling the front camera besides using another camera app?

Front facing camera manual focus
I have the same problem, the front facing camera is almost unusable where there is a lot of light.

I have installed open camera, and this app let me lock the exposure of the front facing camera.

any solution found of this? i can hardly use the front camera because of this issue

The front facing camera on the Mate 10 Pro is great for taking outdoor selfies, as long as you want a solid white background behind you. I can't believe more people aren't complaining about this and that there isn't an official fix.

Low light

At the club, at the bar, or just in your mom's basement, nighttime is when you come out to play. Rate this thread to express how the Xiaomi Mi A1's camera performs when no or low light is present. A higher rating indicates that the camera sensor "sees" lots of light in dim conditions, and that the resulting photos have minimal noise. A higher rating also indicates that when the flash fires, the resulting photo is evenly-lit without any bright spots.
Then, drop a comment if you have anything to add!
Low light need Improvement
Low light is pretty week. Camera app is slow to capture and subjects need to be dead still to produce a usable picture
well overall device is great only weak spot is camera in low light outside in daylight camera performs great but in absence of light there is tons of noise it's like a 3 mp camera image don't know whether a software update can fix that and when mi will provide that or just camera sensor is not capable. i think xiaomi should have asked google to modify camera app also
In low light the cam is more or less unusable.
Yeah, we know the problem. It is not camera itself issue, it is camera app.
Low light performance is just Terrible, no escuses for that.
Low light camera performance is nowhere. Not even low light even in indoor location camera sucks.
Low light photography with the inbuilt Mi-ported camera app is terrible. Pictures clicked had a high amount of noise in manual mode and focusing too was bad. In the HDR mode and with flash, pictures had unrealistic tinge and destroyed the quality. The Portrait Mode works comparatively better however the light entering the photo lens somewhat decreased.
Overall, the app itself needs improvements. The hardware is more or lese fine.
Hardware camera is good for its price. I compared side to side with my old Samsung A710 (f/1.9 vs f/2.2), and the stock camera APP beats the samsung hands down. In low light, Xiaomi pics are darker but with more details. Samsung night mode makes brighter images, but more blurry and with more noise.
Then, if you root (systemless with magisk works great) and use the ported Google Camera then it's a completely different world... Pics become even brighter and more detailed. Different versions could give smoother images or more detailed but noisier ones, up to your choice.
We can't compare vs an Iphone or S8 camera ofc... but in its mid-tier range camera is great for everyday usage.
PS. Using Oreo build, never tried Nougat stock cam.
The Mi camera app considered good enough, though I admit the low light photos are terrible. What's more worst is that the HDR image is really bad compared to non-HDR in quality.
sideport with GCam HDR+ whichever version that suit you.. then have fun with it, if you're not satisfied with the result then it is time to use a DSLR with a 50mm 1.4 or the L series 1.2 for those low light moments.. :angel:
For me, the build is just okay, I'm like holding my OnePlus 3T.

to me its not that bad , use google camera , lowlight photo seems better than stock camera
But the front camera is really bad whether it's gcam or stock. Most of the time it produces blurry images.

from my perspective and experience, the front camera with only a 5 MP resolution, using the GCam resulted in a much much better sharp and crisp image.. especially the portrait mode.. (compared to the stock camera app)
it goes back to HOW we take our photographs, steady hands and a moment (around 2-3 seconds while it process the picture) and I never took only one shot, I took many shots then pick which is the best, delete others..

During low light i can't have a good group selfie neither from stock nor from gcam. Most of the time it's blurry.

have you tried using the GCam with flash?
if you have, then there's nothing at the moment an option that I could recommend using :angel:
while using the GCam, let the auto focus (the circle thing) do it's work untill it dissapear.. then press the shutter :fingers-crossed:
I really don't understand. The camera module itself is pretty capable, but the software is putting it back. God I hope G Cam supports dual lens.
Is bad, is real bad

Terrible camera quality on stock oreo

After oreo update my camera quality turned from great to sometimes impressive to pure disappointment. Photos come out blurry with no details on objects or faces or hair. Is there a way to fix it? I took a look at the settings everything is set to its max quality setting. Hdr did nothing to improve results, same bad quality with auto, on or off. Google camera app also produces similar quality results. Any suggestions?
I can say, without doubt, it has something to do with your phone specifically.
Have the stock Oreo update here, both front and back cameras work fantastically. Nothing like you describe.
First, I'd try a factory reset, make sure the lenses are clean, and re-check them.
You didn't mention if you were referring to the back or front camera.
Selfies with the LG app are still awful, as they were with Nougat, although in Oreo there is a slider to adjust the level of image processing, But even at the minimal level when you zoom in it looks like a brush drawing.
The above problem can be completely overcome using the ported GCam app, discussed extensively in other threads.
In contrast, the native camera app does an excellent job with the main cameras in most scenarios, especially with the new "bright mode" in very low light situations.
Again, in certain situations the Gcam does a slightly better job. The main issue with GCam is that it uses "bursts" of photos and then HDR processing to make these great sharp photos. This works great in static situations but if the subject is moving (like with children) there will inevitably be blur of the subject. In these situations the LG app does a better job.
Since you are reporting a problem specific to your device there is probably no "fix" other than try resetting it, use Gcam, or there is physical damage to your camera.

Haven't run into that problem with the Gcam I'm using. Though I use normal HDR+ and not HDR+ enhanced.
Yeah sorry for not fully describing the issue. I have some pre update photos from the back main sensor as well as the wide angle one that look fantastic , after I updated to oreo , everything turned blurry and washed out. Will try to factory reset the phone and take some sample shots to check if there is any difference . Thank you all for the replies.
Let down by the same issue.post oreo update the photographs from back camera are overexposed and washed out and the colour accuracy and clarity has taken a kick in the gut.
Same here, since the Q Lens option has appeared on the screen.I still have my lgg4 and thats crystal
What about try to replace Oreo camera with Nougat (7.0) one? It would be nice to compare pics from both versions in Oreo (any download Nougat camera only?).

low Light problems photos from stars distorted with S9Plus

Hello,
i take photos from the night sky since serveral years (with smartphones too).
Unfortunately with the Samsung S9plus the stars are not pinpoint like as they are on the Samsung S7. They apear very distorted with a kind of a halo.
Ofcourse the smartphone was not moved during 10 seconds of exposure time.
I did layed it down and used the self timer mode to prevent shaking.
I tried it serveral days in comparison with the Samung S7.
The S7 is always much better and show pinpoint like stars.
The distortion of the stars is visible in the RAW files(DNG) too so no jpeg problem forced by the compression.
Could you reproduce the same problems?
I am not allowed to post links.So how to show you the photo?
Could send you the link of the uploaded photos for comparison.
The dual camera variants of Samsung phones tend to overexpose shots, especially during darker environment.
That's what I noticed, and I'm waiting for the update they sent to Note 9s.

Are you using the telephoto camera? It has OIS driven by digital gyroscopes. Those gyroscopes aren't effective at low frequencies so the OIS will slowly drift around a small amount. 1/5 second is usually the limit for sharp photos. Even when the gyroscopes are turned off, OIS lenses are VERY sensitive to motion because of the lens being on a soft suspension. Walking next to the tripod could wobble the lens.
You also can't expect clear images if you use F/1.5.
Try using the wide angle lens.
I would send a photo to someone of you so you can post it here into the Tread.
Who like to do it?
The camera was layed down on the ground so no shaking or vibration ppossible during the exposure time.
I found no setting that the OIS gyroscope is working in photo mode. OIS is probably only working in video modes.
Even if it works in photo mode, the camera was layed down, so no shaking could happen.
Who of you could make a photo from the stars with the following settings?
Pro Mode
Camera mounted or layed on the ground with direction to the night sky.
Self timer to prevent shaking
Iso 800
10sec shutter speed
F 1.4

Antwort unfortunately the tele lens only works in very good light conditions.
Even in a bright lighted room there is no way to activate the real Tele lens. The camera automatic switch to digital Zoom.
Also in pro mode its not possible to use the telephoto lens if the light condirions are not perfect.
This is very bad because if the cameras is standing still completely and the object doesn't move why not using the Tele camera lens in pro mode?
Very interesting Thanks for the link

Wide camera and selfie camera has fixed focus

I got my G8X yesterday. Overall it is a great phone. One thing I noted was only standard camera can do autofocus, while wide and selfie camera doesn't. For example, using selfie camera, if I put the phone at the distance I would normally use, I got a blurry image because it does not focus. You can tap the screen, all you get is adjusting exposure. You dont get focus sound. This is not a deal breaker for me. But just would like to mention to you guys.

Question Camera quality?

How is the camera quality? Im coming from S22u
Battery is ok. Zoom definetly not the camera to shine. Ultrawide and standard lens are very good. However, coming from an S22u you might have a downgrade..
Main camera captures a lot of details and offers a very good (and bright) night mode. Ultrawide and tele are "ok cameras". They can take good pictures in some conditions but don't expect much, they are not in S22u or i13 Pro territory. You'll notice too that the default camera app tends to oversaturate colors. Sometimes overly So. I got Gcam for that reason. The front cameras for selfies are also ok cameras. In poor light they are almost unusable for me. I recommend using the main camera for selfies. Find N is a great phone but the cameras are not the highlight.
Cameras on this Oppo are very good. Samsung S22 Ultra is plagued with horrible shutter lag nobody talks about. Not anymore since I upgraded to Oppo find N. And here you have proper 50mm portrait focal length unlike 75 (3x) they now put in every flag****.
