Anyone here still having the excessive lens flare issue? It's hard to tell if this is just a handful of unlucky people with a bad camera assembly, or is inherent in the design of the camera, but Google's supposedly promised a software fix -- somewhat laughable considering such flare is most definitely a hardware/lens issue and lens flare is highly variable. If Adobe cannot come up with a one-step flare-eliminating filter in Lightroom or Photoshop, I strongly doubt Google can come up with one in a phone.
It has lens flare. All cameras do. This one is a little more obvious than some. They plan to mitigate it with the HDR post image processing, but I doubt that will completely eliminate it. That's fine, because any camera will show some lens flare when shooting at a light source.

Google have an advantage over Adobe though - they have access to all the RAW camera data (multiple frames for each individual photo) and also the various other sensors and can actually alter the camera behaviour in response to it (i.e. like changing aperture to move the position of the lens flare).
HDR+ already takes a succession of shots, they could always take one shot with a different aperture setting and use that to "heal" the lens flare if one is detected in HDR processing. Probably won't be perfect 100% of the time but would be an improvement over what is happening now.
The low-tech workaround for now is to put your hand at the side where the strong light source is originating (being careful not to get it in the frame) so it acts like a lens hood.
Hi all, I did a thorough analysis and posted it in reddit so the Essential staff can see it. Here it is... Please post your replies and comments here along with your comparisons and settings listed please. Thank you!

I have read your post. I did see the update that Essential released and although the file size is about 1 MB bigger than before the update, still the image quality didn't change. I am using this version: MGC_5.1.016_7.0+C2API_v.1.3a_AllinOne. How is it different from your version of Google Camera app?
why do you think the portrait mode does not use the second camera?

Well two reasons, they never really mention what focal length the second camera is, most flagship say its a 2x optical which is a typical 52mm lens. Second, you can see the stapphy's pic, the bokeh is way off.
well i can not fully agree with you. i admit that i have no technical details for constructing pictures with two cameras but i made a simple test: i put my finger on the mono cam:
monochrome cam covered:
both cams free:

Interesting, I was only saying that because most true portrait set up needs a telephoto lens bc of the focal length 52mm used. The latest OP5 removed their telephoto lens and created portrait solely by upscaling pixels taken by the second lens. There is a article on gsmarena that explains this, so maybe essential is doing the same?!? But to me, anything not using a 52mm setup for portrait is all software emulated.
Essential had mentioned that both cameras are the same focal length (or at least appear to be, they didn't give specs). The difference is color vs mono. And if you look into stereo photography, which has existed since almost the dawn of photography, it's composed of 2 lenses at the same focal length slightly offset from one another similar to the dual camera setup on this phone. It produces 3d images. This is because each image is slightly offset from the other, producing a slightly different perspective. This is also how we see depth with our own eyes.
If you can produce 3d/stereo images with 2 lenses next to each other, then you could calculate how far the images are offset from one another by overlapping them. Where the offset is further, you might assume the object is further and thus produce a shallower depth of field there.
Where I'm unsure is how the expected to combine the 2 images because they won't match identically. Either they're so close that stereo imagery as I described has little to no offset, making my point above completely irrelevant and allowing them to be combined as originally planned, or there's enough offset that they're having difficulty in combining the images which is why there has been very little confirming it's actively doing this.

Excellent analysis! The prior 2 lens system that existed was used for 3D purposes only. However, now there's softwares involved that pretty much said to ignore anything that is behind the main focus point regardless of how minimal the depth differences are. The 7 Plus didn't even make use of the telephoto until it detects an X amount of lighting present. There was a video just surfaced to show how the iPhone X turns on it's telephoto at a lower lighting than the 7 Plus or 8 Plus, I forgot which one. Most dual camera phones without telephoto lens is pretty much just like you said color and mono, and the mono allows for better color. The camera system would merge the two together to enhance color, not needing a larger aperture for low lighting since the mono takes care of that.

I don't think you're accurate on one aspect, but otherwise yes. The mono camera doesn't do anything for color. It is physically impossible to capture color data on the monochrome sensor. Rather, that sensor is missing the layers/components that filter light into red, green, and blue. The benefits are less objects on the sensor blocking light passing through and possibly (depending on design) more surface area to capture light. So the mono sensor captures more light and more detail. Combining the 2 images is supposed to offer more detailed images and help with exposure. Anything to do with color is from the color sensor and post-processing. Quality lenses can also help the color accuracy, but it's unclear if the lens on the camera is as good as it can be or not.

Oops, I don't mean enhance color as in Saturation and color itself. What I mean is like making the pictures more details with color and contrasts that sort, shadows and lighting. However, it is interesting the guy above cover the second lens and bokeh went away.
Don't know about you but what we have "selective focus" or whatever they call it is a complete trash 99% of the time. We have 2 cameras and they can make great photos. They are perfect for Portrait mode but there is no one to add it I guess.
They added Live photos - Another thing half baked. Can't be used outside of your phone... At least Huawei phones are feature rich, they could make some way to export them as a GIFs or ot export the video so we can share it on another places.
Now they are adding 3D Panorama Camera Mode (there is XDA article about it) another thing NOT SO needed.
Why not invest some time and do a Portrait Mode so we can make great photos?
If you agree with me, send your feedback to Huawei from HiCare app.

Who knows maybe they will add it later if we give enough feedback.

Wide aperture mode and potrait mode are similar. I think the only difference is you can alter the blur in wide aperture...
Trick with two cameras in P9 is that they are not used at the same time even to create bokeh effect. It was tested many times with covered lens or even when putting some bright thing to fool camera not to show info "dont cover lenses".
So sadly we talk here only about one sensor that still is damn nice, so at least for me its not big deal.
As for portrait mode... It would be nice to have but what we really expect from it?
Most of portrait modes on phones are actually the same as "beautification mode" where camera just slightly blur skin color and do some really small blur on background.
Its not really much and I actually found out that "beautification mode" in our device at level 3-4 do the trick just fine. Also "Food Mode" is pretty nice for portrait, it bump colors and(not sure if its me or that function) focus more on close objects so background have that light blur.
Other thing is that if you really want to make nice portrait mode... Expert mode is best to do it. Yes it need that few seconds to get set it up depending on lighting condition, but for most of time its a matter of selecting aperture mode, AF to manual(its tricky on phone but you can get used to it) and correction of exposition.
Also people should not be afraid of post processing. This is something that actually distinguishes professional photography from amateur. Whole magic of nice image is correcting it after taking picture. Not some heavy photoshoping, but "correcting image".
People today want everything automated and expect professional results. They take 100000 pictures and want them all to be nice.
Yes, photography is about taking lots of pictures, but what matter is to choose that one best, and polish it as much as possible.
Taking portrait is not different, you take few pictures, choose best one and polish it a bit after that.
You will never get perfect result with automatic mode in first try, this need some luck or proper preparation of scene, that no one really do when take pictures using camera.
The wide aperature (not called selective focus) is actually the portrait mode, similar to the one on iPhones(also on Note8).
It does use both cameras to percieve depth and create a bokeh/blur effect.
And if you are talking about P10's portrait mode, it is just the wide aperture mode along with beauty mode combined, and is inferior.
I think P9 does a decent job with it's potraits. It's not the best when compared to Pixel, iPhone and Note 8. But a little bit of tweaking and manually taking the photo at a good distance from subject. You can get great results. Plus you can't expect everything to be in the phone, as there are certain. limitations hardware wise. Best you can do is to see tutorials or find ways to manually tweak camera settings. Or you could get Autofocus, terrific free app that allows you to make potriats out of normal photos and it's very good.
Personally I don't find it the same as Portrait Mode on other phones. Especially with objects it's ridiculosly bad. About the two cameras I guess there is a way to make them work together and give great results. But even if they add it only for the one camera I would be really happy. It's not necessary but would be nice to have it. We see they are adding new things this one will be wellcome.
It's simple. Instead of using a button named "Portrait Mode", use the manual Settings to create portraits and bokeh effect on your own.
Because everyone knows how to use manual settings to achieve it right? Not so simple. Mode is better.
If you managed to ride a bike, create google account, register on xda forum and use phone it self at all, manual mode will be peace of cake.
Its a matter of just remembering what option do what, and you have really just 6 options where 2 of them are really clear to understand and not used too much(White Balance and Focus Mode that is just manual and auto).
Separated modes are handy, but they often "try to hard to be inteligent" and mess thing up. Its especially frustrating when you transfer images to PC and realize that image on phone look totally different than on PC, especially in terms of contrast and details...

Are You sure? I tested it on my P9 and covering one lens (mono) has an effect... Just look at the file size and histogram. I can clearly see the diference (with covered lens there're less highlights).
Of course in PRO mode without RAW. RAW is taking photo from ONE lens.

There was few comparisons topic even here on XDA, but here have another one. Taken in a bit dark room near the window with just natural sun light. I used small tripod on table.
Normally I would use big one and take pic outside, but I dont have big one with me and its windy as hell and Im not in the mood for going outside
Beside here we focus on details of image, not on bokeh effect, so such close up is enough.
I used both method to cover BW lens. Simple thick tape, and second one that prevent phone from showing warning about covering lens: Bright single small LED diode facing straight in to the BW lens(its really tricky to set it in way that it dont reflect in to the other lense...) It not cover image but give big bright white blurred blob in the middle of image.
Image is saved in PNG format so it should not have additional compression artifacts.
https://goo.gl/DK1rjR
(of course download it for 100% size)
As you see... all images have almost the same amount of details. Of course BW look best especially with help of lower ISO.
Overall only auto mode lost some details but you need to stick your face to the screen and literally look for them, so I call it draw for both auto and manual.
Of course we need to remember that scene it self have lots to say, so with different lighting and scene you will get different image size and auto mode settings, but overall you will get the same results: There is no difference in image quality if you cover BW lense, even with bokeh effect.

Hmmmm... Im not talking about human eyes
The difference is too small to catch it, but if You look into file sizes and at histogram there IS a difference. Not huge, but there is.
The problem is... Huawei told us, they're using two sensors to produce one image. And its true, but its not like as twice as much light unfortunately. Difference is too little to catch it and say that. Covering the second lens is cutting some highlights, thats all... (right side of histogram).
I would love to, that camera is taking light with monochrome sensor and then putting colors on it... It would be AMAZING! Just take color and monochrome photos with same scenery. The monochrome photo is almost twice as fast as color (or has twice less ISO).
Why is that? I dont know, its a shame. Anyway its super camera still.
EDIT: Maybe for different ROMs its different?
Honestly I dont really care if it use both sensors to take pic or not. Its nice camera and that what matter. Many people including me tested it many time, and difference is non existing if you compare them, for most of time difference in size or histogram is a matter of just different settings and small changes in scene lighting, even small tilt or movement of camera can change it. Even if you just focus on different part of scene, there will be change in light expo(it will bright or darken some part and you will get totally different histogram and size). I can ensure you that if you put your phone in tripod and take proper test images without changing scene lighting too much you will never find a real difference, even with slightly different histogram(I actually dont get focusing on it that much... its like rating music relying on its spectrogram)
As for using two sensors and blend both images to create one... Today cameras and hardware is fast enough to take even 3 pictures instantly with different settings(exp, focus), so even with just one sensor you can get nice images that have nice dynamic range, bokeh effect and details.
So dual camera with both the same sensors are really just marketing gimmick and some people get that bait and spread false info about "superiority of dual cameras". Its a matter of creating ONE good sensor with good image algorithms to get perfect image(like proper cameras doing for past decades?). And I dont afraid to say that P9 have really nice camera and monochrome sensor is just additional feature, cool to use but not needed at all.
Yeah mulit-lenses have their pros, but we talk here about phone... you can stick on it additional wide angle lens, but beside that playing with blending images from few senors is overkill.

You can't reproduce wide aperture effect with pro settings. You can't adjust focal length or aperture.

I happen to disagree, multiple sensors can be useful for zoom without losing detail (that's no gimmick), monochrome let you take pics with less noise in darker scenes (I really like that) , the bokeh effect normally use both lenses to create the image. In other phones, LG's for example, the wide angle lens may come handy in numerous situations. Sure, you can have one great camera and be satisfied but I don't think that multiple sensors are just pure marketing.

eh... I said that, quote: ""So dual camera with both the same sensors are really just marketing gimmick"". I was referring all the time to two identical sensors. Read whole topic...
I mentioned that having telephoto is different story, quote: ""(...) you can stick on it additional wide angle lens, but beside that playing with blending images from few senors is overkill.""
But still as I said al whats matter is quality of that sensor and software side of it(algorithms), there is lots of phones and camera with just one senor but because of quality of optic and optimized software it give you better end results when you compare it to any dual cam in 1:1 comparison
This question is especially for the S8+ and upcoming S9 or new iphone. The sensor on the telephoto lens is always much smaller and quality much worse than the main lens so far.
Also, any luck on whether S9 will support 4k60p at h265?
Any comments?
Well, when you zoom in, you lose some quality by "cropping" the incoming light. Resolution is dependant on sensor, but if you zoom in you are taking a smaller portion of the scene that you see, if you get my point. It's not that tey don't want to, it's just physically much harder to make a zoom camera the same quality as a wide angle camera on such a small form as a smartphone camera.
Enthusiast cameras can have variable focal length lenses, they have complex lens combination that are physically adjustable (so called tele photo), when you 'zoom' there's no loss of resolution.
All cameras on mobile phones are to my knowledge fixed focal length lenses, the only zoom is digital which as Ertogrul implies reduces resolution.
Digital zoom is very much the poor relation in terms of image quality, but then we get what we pay for and a good tele photo camera lens will typically cost considerably more than any high end phone will cost.

Hello,
I have bought just yesterday the normal version (non pro) and I would like to ask if anyone knows the differences at the pictures between the 7p and 8p lenses? In theory the 8p can capture more light, but how is this translated in real life? Does it worth the extra money for that difference? (I have a 14 day window to return it this is why I ask)
Thanks
You will be blown by the photos you take with the normal version so you don't need to buy the pro version 6GB ram and 128GB Storage is enough for everything from gaming to taking photos, browsing and anything i can say.
No I really don't care about the more RAM and Rom. Just curious about the photos only!
I ordered the Pro. Should arrive next week. Frankie Tech on youtube will upload a camera comparison of the two very soon.

amount of lens group doesnt mean you can capture more light. Extra lens is used for correcting distortion, color aberration etc. The apperture itself is the same pro or not pro. So it should be able to capture same amount of light.
in daily usage, difference in camera result will be minor
Xiaomi said it should capture more light.
Why did I go for the Pro
Sorry if out of topic, I have a plan to buy this device, at the moment speak about lens (and apperture), some one says (mkbhd & droidlime) this device have a small focus area, and create a small focus object and large blur area, event the object is large in frame.
Maybe it's personal preference, but can this character can fix (create focus area larger) by software update or it's a hardware character and cannot change with software ?

If anything, extra lens element is actually one extra layer of glass/plastic that will filter any light captured. So, better image maybe yes (by slight), but more light ? Am not sure how that works in photography logics, lol

To understand this, you will need to understand the correlation between sensor size and depth of field.
Put it simple, bigger camera sensor have capability to geta shallower depth of field.
This is an advantage if you like to shot some scene which have a distinct foreground object, and want to have good separation with background. Think portrait, for example.
But this might become disadvantage when you try to get a lot of object to be in focus. Example would be a group shot with some people standing behind others. The one stand behind might be already out of focus range.
This is hardware characteristic, which applied to any camera out there. Back in film era, this happen to medium format cam. In digital camera era, you can compare the depth of field between full frame camera, APS-C camera and Micro 4/3rd camera. Image from full frame camera (which has bigger sensor than other) will always have smaller focus area (shallower depth of field) when being used in same apperture setting.
This is physics. Even if you try to compensate it using software (by put sharpening in object that located further from camera), it still there, the effect.
The only thing can change this is if smartphone camera start having an active apperture system (you can change F value). But since by today, all smartphone still using fixed apperture in its lenses, nothing can be done related to what you ask.

yeah doesn't make sense but at the same time Xiaomi didn't add another lense for the lols and didn't give that exact version to Dx0Mark for no reason...

The extra lens definitely not for lol. Extra lens element is used for variety of reasons, mostly to correct distortion and color aberration. But definitely not for extra light reasons.

Usually in a Lens group, more len can capture more light is true.
for example, 8p lens maybe capture 99.5% of light, but 7p lens maybe only 99.2%.
The different is not big.
But "more light" is not the major benefit.
Usually more lens may correct the image better to fit the sensor.

This is physics. Even if you try to compensate it using software (by put sharpening in object that located further from camera), it still there, the effect.
The only thing can change this is if smartphone camera start having an active apperture system (you can change F value). But since by today, all smartphone still using fixed apperture in its lenses, nothing can be done related to what you ask.

Hi otonieru
I appreciate you explaining the relationship between sensor size and depth of field.
My new note 10 pro main camera seems to have trouble focusing even in good day light, it repeatedly focuses on the background instead of the person i want to photograph, even though i physically tap the person's face on screen. The 5x camera focuses fine though.
Do you think this is a hardware or software issue?
Many thanks!
