Wide angle camera is darker than normal camera - OnePlus 8 Questions & Answers

Hello to all,
Just got my OnePlus 8.
When checking the cameras, I noticed a significant difference between the normal and wide angle cameras.
The wide angle is much darker and sometimes seems to have problems focusing.
I have not found many threads on Google (and the few that I found mention blurriness, not darkness).
Does anyone else have this issue? Could it be a hardware issue?
Thanks for any advice.

So very strange. After a lot of trying last night, I wrote the post above.
This morning, I can't reproduce the issue. Both images look very similar in terms of lighting.
Il post back of three issue comes back or if I come to understand what happened in the first place.

It's normal due to hardware limitations. The wide angle has a much smaller aperture (very common in camera lenses and phone camera).
Smaller aperture means less light can be captured, think of it as your eyes
If you almost close your eyes (small aperture) what you see is darker.
That's why despite the same megapixel count etc, wide angle photos are darker and noisier, and if the software try to compensate , it needs a longer shutter speed (longer shooting time), longer shutter speeds means shakes and movements are captured, resulting in blurry photos, and since the wide angle has no OIS, it's even more likely to come out blurry if you aren't super still while shooting.
Hope this helped

Over sharpening of camera image

Can anyone confirms this? Almost 4 units i tested from sony stalls has this issue.
The photos taken by camera turns out to be overly sharpened, with lots of artifacts.
Turning on or off image enhancements does not help.
I am seeing this as well. And most of the reviews I saw also reported this.
Currently I am trying a few third party camera apps to see if they do the same
Haiz.. Why can't they make the camera right for once?
I concurred this. Mine focused good. I learned a trick that you actually have to tap the screen then press and hold the camera button on screen or side until it is clear. When i first got it, all my photos was focusing on the wrong spot. However, now with that trick i could get sharp images but zooming in they look very blurry and a lot of noise.
Do you experience this is good or low light? You do have to work a little bit harder with the camera settings as the light drops off to get the right image. And use the designated camera button too rather than the on screen one.
Good lightings... Not to mention if its poor lighting conditions. Guess have to wait for a new firmware.
Yep so much sharpening in all lighting conditions. Hoping for a software update soon.
Here is samples pictures from my XZ. It has undoubtedly the best selfies camera under daylight. Lowlight shooting takes a bit to get used to it. It was bad as first but if you toggle on "tap - focus and brightness" in setting it will improve tremendously as it uses it light sensor to automatically brighten the photos. Overall, I'm happy with the camera. It beats Iphone 7 Plus and on par with the S7Edge. My beef with the XZ is the small size and 3GB. I would prefer 5.5 and 4GB for a $600 phone. But if you can get it for $450 or $500, this phone is definitely worth every penny.

I am not talking about selfies. I am talking about the main camera. Very bad quality here. So fall 8 sets i have tried, same issues
Noticed this myself, not impressed with the image quality. Seems to be worse than my Z2. Hoping when they eventually drop Nougat it'll iron out some of the issues.
About blure and noise, increse ev to +0.7 or 1
A very good example of xz camera samples. You can guess which photos are by xz. The oversharpening of images when zoomed in.. Soo much artifacts.

Christmas light "flares" in pictures?

I have an S7 and iPhone SE. Generally speaking, the S7 does better (though a little more yellow) than the SE in lower light scenarios. However, when it comes to these lights, the S7 keeps adding this awful flare or reflection or something. The SE doesn't do it. My wife's iPhone 7 doesn't do it. It really ruins the photo. I've attached an example (cropped) from a family member's house... but it's consistent in other scenarios similar to that - lower light, some dynamic range in the photo overall, etc. It does seem to only be in the portion of the photo (again similar elsewhere) that's closer to me as well. I'm about 4 feet from that front post.
Is this normal? Is this just an inherent part of the way the S7 camera handles things? It's perfect in every other situation and this is the first time I've come across an issue like this with it.
Thanks in advance for any input.
Obvious question but is the lens clean?
And HDR disabled?
Lens is clean, and HDR is on Auto. I never turn it off as it's been reliably good up until now.

Test it with HDR disabled, HDR takes 3 images with different exposure settings and merges them iirc
And it is well known to be a little buggy anyway, leaving pink dots on photos
Might not be that, but if you want to narrow down the issue you need to test everything

Agree, but based on the stats on the photo, it's looking like HDR was indeed disabled (or it would've indicated HDR right?)
I've read about the pink dot issue and never seen that on mine - and this doesn't appear to be the pink dot issue. The spots are clearly reflections or flares off of the lights that are closer. They're just so significantly worse than other phone cameras I've used. On the iPhones I referenced, you can see small tiny light dots in other parts of the photo, but they're much more inconspicuous and don't take away from the photo.
I'll keep playing with it this evening and see if I can narrow things down any more. I just wanted to see if others had seen this or had an "issue" like this, or if it was just a difficult spot that the S7 couldn't handle while other top-tier phone cameras could (if so, that would be a first in my experience).

I think so honor 8 camera dual tech is fake

I've been honor 8 since one week and i have found one thing that when even i cover right side lens it capture black image but when ever i cover left side sensor it's take snappy sharp image like it's ideally take . So i think so it's just fake second camera is dummy or any other problem ? please let me know i'm worried for my money
Are the pictures good? If so then don't worry about it.
Sent from my SM-T713 using Tapatalk
From my experience the second camera is mostly used for background blur effect. If you cover the lens, everything is in focus.
It is also used for minor noise reduction. If you take a picture in low light and cover the secondary lens there is a little bit more noise. But you won't really notice it unless you enlarge the image.
well the fact that when you block one lens, the other works is proof that neither is dummy. perhaps the post processing is not that dramatic as you were expecting. try taking low light pics with both and just the normal lens then compare them by zooming.
no difference found
I've tried in low light too but second lens is just a fake . it's don't enhances quality i think so i have to wait for android N update

I love the pictures the Honor 8 takes when using the Wide Aperture mode. It seems the second camera is essential for creating the blur effect. If you haven't noticed you can go into the Stock Huawei Gallery and adjust the wide aperture pictures after the fact. Even if you took a picture that looked like you focused in on the wrong thing, just go into the Gallery, click on the wide aperture button (only shows up on wide aperture pictures) and select what you wanted to focus on.
Sure enough, without the second camera the wide aperture mode doesn't work properly if at all.
Second lens is for focusing, depth of field, and additional light. As well, when covering the second lens, it persistently gives a warning about not covering the lens while shooting, especially when refocusing. I think this should be enough to disprove your "fake camera" theory.

Camera vs S10?

Any one able to compare the camera with the Samsung S10? Is it better or worse?
Having both phones, I can say it's worse.
The main issue really is the exposure and whatever HDR+ algorithm they're implementing in the stock camera app. Even though they said it's the same HRD algorithm that was applied by google for pixel phones, I still think it's over exposing everything especially the low tones and shadows - this produce a very unnatural looking picture. (If I wear a black shirt, my pic came out as if I'm wearing a gray shirt due to overexposure on the shadows).
On the other hand, I'm really loving the flip camera and the ability to use wide angle for selfie/group selfie and video. That is definitely the highlight of this hardware. But I will be lying if I say I'm not struggling to love the quality of the pictures produced by this phone.
Have you tried the GCAM port? for me it produces better pics...
The Asus stock camera is hit or miss. Too inconsistent for me, especially the HDR++ mode.
But with arnova's GCam port it is simply amazing and blows away even the pixel 3 cameras.
The wide angle camera in our Asus does not focus as good as the main camera ..try it..also the slow motion videos are not that sharp and crisp.

Agreed, that there is sometimes overexposure, but I like more Asus camera's bright photos instead of GCAM darker photos. GCAM is better in very dark, but I prefer Asus camera often, specially for low light photos. Well, I have exposure compensation + 0,4 in GCAM, but still ...
I can easy say that this is the best cellphone camera on the market now, I installed Gcam and activaed raw.
I have never seen a phonecamera produce such a good raw files, even in low light.
Skintones, natural colors is great on this camera, Samsung, Sony, Huawei. and lot of other manufactors are terrible when it comes to natural skintones, overuse of noisce reduction....
Also the 4K 60fps is very natural and doesn't have the unatural look that almost every other brand have.

Camera OIS/sharpness?

Hi folks,
I am presently playing around with my P40 Pro, especially the camera as this is of special interest for me.
I am comparing with a Oneplus 8 Pro.
What I noticed is that the P40 Pro camera is giving a lot more blurred images at medium to lower lighting, in fact it's surprisingly diffcult for me to get a sharp indoor shot.
This is on .122 Firmware and I am bit at a loss on how to tackle this, in fact it's a bit disappointing for such a hyped camera.
Isn't the P40 pro camera supposed to have OIS?
And this is with very comparable aperture and shutter speed between OP8P and P40P...
Am I the only one? Any suggestions?
Thanks,
Axel
Are you using Google services?

Yes... Why?... Is there a known influence?
What do you exactly mean by blurred photos. Motion blur or out of focus blur? Motion blur is caused by slower shutter speed. Focus blur by focus failure. There is also blur(bokeh) caused by much bigger camera sensor used in P40 PRO. So depending what your subject is you may experience different results. Longer shutter speed and lower ISO is preferred for best image quality as long as you have static scene. But in scene with moving object, object in motion can be blurred. Personally I am on .121 and I rarely get blured photo due to any phenomena described above.

To me it seems like motion blur from camera shake... But images at around 1/30s with OIS should normally be fine - at least they are on the other handsets I tried...
This is why I am asking, maybe OIS is not working... Anybody got an idea to test this with some tool?
Have you contacted Huawei customer support? Could be faulty, it also may be worth checking out the huawei community page to see if that is the case

Yep, that's my fear.... Well, I am still within the return period, maybe it makes sense to go back to the dealer instead...
EDIT: seems a factory reset fixed it, now I need to discuss with myself whether I try to go without Google for the time being....

Well, it fits to my experience, as written above. Sadly that nails the coffin then, the P40 Pro is going back Thanks for sharing, though
Yeah, firlando code method creates on my night shots some effect lines and on a1234567 method i have good night shots but blurry fotos on daylight... Today i will try to use my phone without Googleplay services...
This installing method on Google services witch you need to go on apps and delete playstore etc i think is the keys for the problem... We need a clean installation without deletations..

Wrong
Observation about the lines in the foto. Lines are reflections from lights. I realised it today. Im testing camera without Google services. Tomorrow i will test on daylight.. I think 121 update is bad update.. is there any way to roal back to 112?
Here its a foto without Google services... Still no sharp almost blur... I think is Just the 121 update is worst than out of the box 112 version
We just w8 the 127 update

I am also disappointed with this update (121) pics quality is average but video quality is lower than on p20 pro.
Zoom doesn't seem to work properly either - it's digital up to 8,5 -10 x then periscope kicks in.

Erm ... I don't see anything wrong with that picture.
You focused on the closed petal at the left side, it's perfectly sharp, rest blurred as it should be. Not the prettiest bokeh, but okay.
Do I overlook something?

Again, I don't see what's wrong with that picture. Maybe you could point out the problem a bit more in detail?
It would also be quite helpful for sorting out culprits if you (and anyone else) accompany your pictures with some EXIF data, like shooting mode, AI on/off, ISO, exposure, aperture and zoom factor. Unfortunately, XDA seems to remove that data from posted pictures.

That's indeed the case with firmware .121. And it's far worse in the "Pro" mode, rendering "Pro" mode almost useless.
Let's hope the next updates home in on that fault.
Look the sharpness on 112 version

EXIF data? Answers to me previous questions?
These are important information, e. g. telling me about the aperture of the lens used, making a difference regarding depth of field, possibly explaining why you *perceive* a picture as not okay.
Besides that:
Similar quality, similar sharpness - if not identical.
This time, there was more distance to the subject, widening the depth of field, the "sharpness range."
Let's assume the picture was taken with the main 50 MP camera, having an aperture of f/1.9 - a big difference to the aperture of the telephoto lens with f/3.4.
The smaller the f-number, the larger the physical lens opening. And the larger the physical lens opening, the shallower, smaller the depth of field.
Meaning: With a shallow depth of field, a few millimeters more or less distance to the subject can make the difference between razorsharp and blurry. Result: Only objects exactly within the depth of field are rendered sharp.
With a wide depth of field and a larger distance, like with the telephoto lens, it's less crucial, every part of the flower will be sharp.
I would show you example pictures if I was allowed to use external links - but my post count is still too low.
Just try taking pictures of the same flower with different lenses, one with the 50 MP main camera, one with the telephoto lens. With the latter, increase the distance till the flower roughly occupies the same space in the viewfinder as with the main camera.
Important: Use a zoom factor of 10, not 5 - this makes sure your really switch to the telephoto lens. At present, there's a software bug causing the camera to often use horrible digital zoom for 5 x instead of the real telephoto lens (seems to be connected with the metered subject's distance). You can check this by covering the rectangular telephoto lens with a finger. If the picture vanishes, the lens is doing it's job.
You'll find out that the photo taken with the main camera has sharp and blurry areas, while the photo taken with the telephoto lens is rendered sharp everywhere.
That's the results of aperture and distance.
And that's why I don't see anything wrong with your first flower picture: Wide open aperture, small distance = tiny depth of field = tiny area of sharpness.
The way it should be because we all like that bokeh effect (blurry background, making the subject stand out) more than typical "flat" smartphone pictures.
But this benefit is paid with a drawback, the small depth of field, rendering everything outside that "sweet spot" blurry.
Perfectly normal, nothing to write home about.
Oh wait, I'll dare to post a link anyway - hope the moderators won't kill me for that impertinence.
Just took two quick photos right outside my house, clearly showing the effects I explained above.
http://waagerecht.com/kram/Flower_comparison.jpg
Picture is quite large, so be warned.
Telephoto: ISO 50, f/3.4, 1/196 s. Main lens: ISO 50, f/1.9, 1/846 s. Both shot in Photo auto mode, no AI.
About that numbers: ISO 50 tells me there should be no grain in the picture; the higher the ISO, the more grain in the picture.
f/3.4 tells me there's a wide depth of field, so there should be no greater blur. Also tells me the telephoto lens was used. f/1.9 tells me to expect blur everywhere outside the "sweet spot", main lens used.
1/196 and 1/846 tell me about very short exposure, so in-motion unsharpness (camera shake, moving subject) is very unlikely.
And because the telephoto lens has a smaller aperture of f/3.4 (and lenses with a higher curvature), less light reaches the sensor, thus exposure time is greatly increased, 1/196 s versus 1/846 s.
See why I asked for that data?
You'll see that the telephoto shot is all sharp (until you zoom in; lower sensor resolution plus digital zoom, today's modern pestilence), you can even see the structure of the green leaves, while the main camera shot has everything blurred except the flower's pistils.
That's just the way cameras work.
So enjoy your fine camera, it does a great work and does it right.

Jeasus Christ i never used 50 mp sesnor i use the normal sensor for the red flower and also same sensor with pink flower... im changing so many phones every year and i can clearly understand what a foto needs! P40 pro with 122 version is less detailed on normal shots than with 112 , i need t use night mode on day light fotos to get some sharpness..
Also the foto you have posted there is no detailed at all i can taje same photo with my xiaomi mia 3 Stock camera apk... and i can get also much better shots withy GCAM on mia 3!
