pixel camera thread - Google Pixel Guides, News, & Discussion

Pixel has the best smartphone camera Google has ever sold, but it's not without its problems. Users have been reporting a distracting halo lens flare in photos take in bright light.

Google will issue a software update in the coming weeks that it thinks will be able to remove this halo lens flare as it processes HDR+ photos.
If you face any problem with camera please share.

Issue with the camera/camera app

See the attached pictures
Anyone have the same issue with pictures having weird pattern/marks?
Also there are lens flare on the third picture taken with oneplus 2. I took it again at the same position with my zenfone 2 without any lens flare problem, in fact i don;t have any lens flare issue like this with my zenfone2. It seems that one plus 2 camera is easier to have those lens flares maybe due its design (the distance between the glass, the lens and the sensor )??I don't know.... Im not familiar with optical physics..:p Is this a deflect with my camera or just a common issue with op2 camera?

It's common with ANY camera.
It all depends on the angle and distance between the glass that is used in the device.
You may not see it on your Zenfone 2 but given the right angle I can assure you it is there.. May not be as prominent but every camera has this.
My advice > Stop pointing the camera at light sources directly or shoot with RAW and post-process it out if you care that much.
Don't ask me how, Google it :silly:
Oh, forgot to mention you can try and cover the light glare using your hand above the camera but be sure to avoid making your hand visible in the shot and depending your angle and subject matter it may not be possible to do it anyway.
Like I said.. Best way to avoid it: Don't take pictures directly aiming towards light sources.
Thanks for your detailed explanation Stevels. I understand that lens flare is a common issue with any camera, what I want to express is it seems that one plus 2 camera is easier to have those lens flares maybe due its design (the distance between the glass, the lens and the sensor )??I don't know.... Im not familiar with optical physics..:p
Also with regrading to my 1st issue if you enlarge the first two pictures you can see weird pattern/marks on the sky, have you experience this before

Yeah, just a processing problem. Will probably be ironed out with future software updates.
To be honest I'm just waiting for CM12.1 to be released for the OPT.
Then I'll be grabbing the MaxxAudio and CameraNextMod apps and using those
Ordered my OPT a couple hours ago

Can you use the wide angle (back) camera to take selfies?

Hi all - it sounds like the front (selfie) camera does not take the best pics.
One of the uses I wanted for the G6 is to use the back camera (the wide angle one) to take selfies instead.
I won't be able to see the screen, but with the wide angle lens, I don't really need to do much framing I'm guessing.
The only thing that I'm concerned about is the lack of auto focus and if the wide angle camera can focus on subjects about 1 metre away from them.
Does anyone have a G6 who could comment / or post a sample pic of this? This is pretty much the dealbreaker for me to get this phone.
Cheers!
I'm interested in the same question! Would be great if anyone could comment on this, hence bumping this thread.
Yes. Front facing camera is not as good as it should be. Specially in low light situation...
This, and lack of LED notification light are the biggest flaw to me
Back cameras takes good selfies though. I don't have any problem with framing or autofocus. Does a good job with defocusing background and shaking effect is at minimum thanks to new image stabilizing system.
Hope this help you
Cheers
Someone here at xda calculated that all things between 35cm and infinity are in Focus for the wide angle camera.
I also made some tests and I think that he is not totaly wrong with his 35cm.
So taking selfies should be ok.

Camera white balance issues

Howdy, a quick question. Has anybody noticed with the Mate 9 camera that the colors get quite over saturated (especially the skin color) when the photo is taken under artificial light (i.e. incandescent or fluorescent)?
I've had the Mate 9 now about a week and otherwise the great camera really struggles with the white balance in certain lighting conditions.
My previous phone was Samsung Galaxy Note 4 and the camera took some really really good photos.
Thanks.
I noticed more general difficulties of all kind of digital cameras with artificial light. Especially with led or energy-saving bulbs or even fluorescent tubes, ranging from focussing problems over incorrect white balance and saturation to some kind of miscolored yellowish waves.
I have almost the same problem. Photos are useless in bright light. whenever there is bright white color the camera cannot handle it. the result is a photo taken with very cheap camera. useless. Anyone know how to fix it? is it a software or hardware problem?
Never got issues with white objects even on artificial light...! Camera performing well... No blur
I have two Mate 9 here. Both cameras working very well in a way that I sometimes let my Nex at home. They do not better than the Nex but good enough. I have the impression that the one with Nougat works better than Oreo in dark situations, pictures have less noise.
White coloured objects are no problem at all.

[Camera issue] stretching sides?!?

hey guys
I have seen this problem in my xc rear camera photos and also in one my friends' xc, so I was wondering if there is a fix or if it is hardware issue or software related,
photos taken by rear camera seem to stretch the sides of the picture and also are a little blurry in sides
for example if you take a picture of a bunch of people standing next to each other, you notice that faces in the sides of the picture are a little stretched and not in real size!!!

I have noticed the same thing. In portrait photos too the heads look stretched vertically. Not happy at all. I'm going to be selling this phone. To be honest my old Xperia Z took better portrait photos than this one.
This is mostly due to the optics of such a small image sensor and super small flat plane lens atop the camera. Anytime the focal length and the lens curvature are not perfect you get some blurring, and they are only perfect at a single point in any camera systems range of focus.
The stretching of the sides is due to the super short focal length/wide angle lens. Same issue happens if you stick a 14mm close up/fisheye lens on a slr camera. This portion of the problem is often corrected for in higher end cameras with software, Sony recently pushed an update to other xperia phones with the same or similar camera to run the algorithm to correct the un-equal representation.
Compounding the issue :
Smaller flat plane optics cause a lot of chromatic abortion as you radiate out, it's the worst in the corners. This gives it a vignette style are of focus and is just not avoidable either.
Sony made the choice to do a lot of image smoothing to hide their noisy camera and it also happens to hide the abortion as a blur effect. I'd rather have the abortion personally than loosing details in a blur.

I know what's wrong with g5plus camera.

The highlighted thing about g5 plus was also the reason for bad camera. The 1.7 aperture and wide angle camera are the cause here. Though it is good for shots within a certain distance like 10-15 feet. But any further the pictures loose sharpness and gets noisy due to which moto decided to use high denoising due to which the photos look soft. My father's redmi 4 clicks better distance pictures than this. It has 2.0 aperture and little less wide angle lens.
Don't forget that G5 Plus have the same camera sensor as HTC U11 or Asus Zenfone 4 (which takes good pictures on stock software).
Worse photo quality is caused by software (Motorola/Lenovo screw it up).
Did you tried any mods/apps? You can find a lot of these, but I suggest you to try Google camera app port.

I use bacon camera on stock Android without root.
I disabled noise reduction and use hdr with manual mode and stable hands to get though grainy but nice pictures. Though the app is not perfect but it works
When I first got the G5+ I thought the camera was too dark... While a lower aperture may help in low light shots it does cause a bit of trouble for highly illuminated scenes.
HDR does compensate but it's nothing like HDR+ from Google.
Plus, terrible sharpen and overdone Noise Reduction excessive Color NR.
I felt quite dissapointed comparing it to my old Titan (G2)
Anyone tried to mod the camera to enable debug mode? You can disable noise reduction from there

Coming from an old school enthusiast of photography background - you're aperture on your lens (in this case f1.7) isn't going to cause noise - that's a function of the sensor. A lot changed when we went from film to digital sensors, but the impact of the f number of the lens did not.
You might be on to something with the with loss of sharpness though. Typically a fixed focal length lens is at it's sharpest at it's only setting... but they very well could have forked this up.
Given that the camera does pretty adequately with other camera software or other hacks - I don't think it's a hardware issue or lens issue. It could be a cut rate sensor...
It could also just be that whomever chose the default settings for this camera did a bad job

What about shadows in bright scenes such as outdoor scenery?
I mean, wouldn't lens aperture like f2.2 preserve more of these details?
That's a function of the film/sensor.
Your f number controls light and the depth of field (area that's in focus) - a smaller f number is more desirable because it allows more light to the film/sensor.
The only thing different here than fine that I can see is the size/diameter of the lens related to the f number. A larger f number, like f 8 or f16 increases the depth of field and sharpness, but at the cost of light hitting the film/sensor. That results in a longer exposure time.
A wide open f stop means more light and shorter exposure times.
One thing we gained with sensors over film is a wider range between highlights and shadows... You could get more shadows and more highlights. Film could get only so much of that before shadows went black and highlights blew out to white. But you still have a limited range. You can't get it all. In order to keep the highlights from going completely white you have to trade off some of the shadow range.
It's early and I'm probably explaining this horribly. Your spectrum between black and white or shadows and highlights is very long. But your camera sensors capability can only encompass a range of that spectrum. If the spectrum were a line of shades of grey from black to white that was, say, 10 units long, the range you could get in one image might be six units long. You've gotta give up somcombo of four units either at the black end of the spectrum or the light side.
If the cameras loaing details in the shadows that's because it's opting to the highlight/light end of the range.
So lens doesn't play a huge role in what chunk of the spectrum the film/sensor can encompass. But does play a role in how quickly the sensor can collect that info. Higher f number = smaller amounts of light on the sensor = longer exposure times.
My guess would be that the sensor or software is biased toward highlights because it results in faster exposures making life easier for snap shots and selfies.
