Hello there.
So I might have a problem with my camera, not sure what's wrong, but I will try to describe it the best as I can.
When I'm in the Pro Mode, changing the shutter speeds makes the preview darker/lighter as it should, but only to an extant. For example, if I make the shutter speed 4 seconds, the preview is just like the picture, but if I go above the 4 seconds, the preview remains exactly the same, but when I take the pictures, they look more brighter. Same happens with faster shutter speeds, at some point the preview doesn't get darker, but the actual picture does.
I found this strange at first but thought it was normal with this phone, but then I saw this video https://youtu.be/zoMsu0mnrRE?t=172 where the person goes all day way down and up and his preview gets totally dark and bright as it should, while mine doesn't.
Does anybody knows what's going on? Is it a defect?
It is perfectly normal. In the video you just see him scrolling fast, not going step by step. My Xiaomi Mi8 does the same, only changes until 4S, than the image is the same. Don't forget that an image is captured by light, and by software it can only show you what it may produce, and not the final result.

Does anyone know what the Lucky Shot feature is?!?!? I'm the only one in the world trying to figure it out apparently. I'm wondering if it is on both 6P and 5X. I know that 5x has 120fps slow motion, and no burst mode. but this Lucky Shot thing has me confused, apparently it is NOT the same thing as SmartBurst.
from Nexus enginners Q&A on reddit:
"We've done a bunch of things to provide image stabilization: 1. The Nexus 6P/5X has a large 1.55um pixel camera and the amount of motion blur due to hand-shake is lower when you have large pixels. 2. We have a feature we call "lucky shot" internally. When you take a picture, behind the scenes, we select the best of 3 bursts of images. 3. When you use video, we have optic-flow-based image stabilization. 4. When you use SmartBurst, we select the best image from the burst (for example a shot with eyes open)."
It just means when you take a picture it actually takes 3 and chooses the best for you automatically.. It's not a setting or anything.. Just something that happens behind the scenes
cool, got it, but does it work on the 5X or just the 6P.
Both

I like this implementation better than the Moto X's one. It gets cluttered with double takes of pics, thus having me to look through them to see which to delete. I trust Google to pick the best pic
But I think only HDR+ uses this feature.
Because Google advertised HDR+ with exactly this feature.
http://googleresearch.blogspot.de/2014/10/hdr-low-light-and-high-dynamic-range.html?m=1
"HDR+ also begins the alignment process by choosing the sharpest single shot from the burst. Astronomers call this lucky imaging, a technique used to reduce the blurring of images caused by Earth's shimmering atmosphere."
As they title said I tied to find out but am at a loss in trying to find out exactly what is happening when we use the HQ mode in the camera app.
In night scenes it seems to produce a better photo but the shutter speed is the same. One plus have not really said what they have changed since the HD to HQ update so wondered if anyone could let me know ? Is it an extra stop in exposure maybe ?
Just watch this video:

Thanks for the video but it didn't really answer my question as it was only a comparison.
That video just compared the 2 options of HD (which has slightly changed since they renamed it to HQ) and HDR. It does not explain what kind of post processing happens apart from staying it used a de noise filter. I wonder what "exactly" is happening with exposure, contrast, saturation etc when you use this HQ mode ?
If anyone knows that would be really helpful.
Crap. I read it wrong. I thought it said HQ recently got changed to HD. And does anyone elses HQ lag like crazy?

Mine is rooted and running the Elemental Kernel. So I guess that's probably it.

@jdawgg21 Nope, that's not it.
When using HQ in lowlight, it automatically reduces shutter-speed even more compared to the already lower speed in auto-mode.
Lower shutter-speed = lower framerate
1/30s = 30fps
1/10 (mostly when using HQ) = 10 fps
When others say they don't see the lag, it must only mean they did not test this in the same lighting conditions as you did.
It "lags" here too and so does it on every device which will use 1/10 or even lower shutter speed which shows you a real-time preview of what the image will approximately look like when taking the shot.

Finally a sensible answer. Thanks man. I had been asking around and Juan Bagnel said it's probably doing something like a dslr de noise function so what you said makes sense I have only used it indoors with artificial light so probably had no lag but so is what is displayed on the screen if it is leggy is representative of the shutter speed ?
I have heard from a Carl Pei interview that the camera is the reason for the phone having 6gb of ram because it snaps 4 photos at the same time we snap one photo. The phone then automatically chooses the best one photo of those four photos. I reckon that is also a probable answer due to the lag you are experiencing.

No, this is not the answer for the "lag". Why doesn't it lag in good lighting then?
I already gave the correct explanation for this.
As an example: I don't know if you have experience with the OnePlus One. It also started lagging much heavier in lowlightconditions due to the low shutter-speed.
Eventually, Sultan released his modded camera hal which forced the camera to not go below 1/30s on the shutter-speed.
The result was a perfectly fluid viewfinder regardless of the lighting conditions.
I am only talking about the fluidity of the viewfinder here. (Shutter-speed and video-framerate is a whole different story not to be mixed-up here...)
I've seen this interview too,
but I don't agree with him that it takes the best of these 4, instead I think that it somehow combines them into one.
This often results in more blurry pictures, even in good lighting!
Check this video I did on this issue:
http://www108.zippyshare.com/v/KidtanPE/file.html
As you can already see in the video, all images were taken without HQ or HDR. You can clearly see this when taking a picture and quickly swiping to the gallery.
For an instant, you will see the unprocessed picture which quickly changes as processing is being applied! Sometimes to the worse though :/
This gets more pronounced the more the ISO level goes up on a shot.
I was holding my phone as steady as possible and you can see that the shots which are displayed first look sharp before postprocessing.
So how can this be explained when, as Carl says, "the camera takes the best out of 4 shots"?!?
I first thought that in HQ mode, the camera is doing Dynamic Denoise
Grainy pictures are a thing of the past with Dynamic De-noise, which takes several photos and compares them to reduce noise and improve clarity.

However GSMA review says that the Denoise function gets activated automatically when there is minimum handshake and is not dependent on modes.
A few other things I have noticed.
1) On 3.1.x the noise suppression was very aggressive, almost like a water paint effect. On 3.2.x, the photos are more natural. Still less noise that normal mode.
2) The minimum shutter speed in HQ mode is 1/10 while without HQ it is 1/17
3) RAW is disabled in HDR as well as HQ modes. This makes me think that the HQ (like HDR) is using multiple snaps to filter noise that is Dynamic denoise. If you quickly switch image preview after clicking a pic, you can see the transition from normal to HQ happening. This is definitely not normal noise reduction.

This is exactly what I said in my post right above yours and it even happens when HQ and HDR are disabled.
Check the linked video. I bet this is what you mean.
I hate this behavior, often faces are smoothed out because of this, even in perfect lighting conditions.
Hi, it seems the HQ mode does not generate RAW file, someone He checked?

A raw file is a photographic negative without any processing applied to it.
So even when the app would generate a raw file in HQ mode,
it would not look any different than the raw file created with HQ disabled.
My best bet is that the app is saving its resources for the HQ postprcessing,
thus completely skipping the raw part intentionally.

Hello everyone,
I recently bought an M8 and I'm loving it so far, except for the camera.
I'm not running the stock M8 rom but the S.Team-JW-7.5.0 rom (HTC 10 to M8 port), so am I missing Duo camera features or something?
Do you guys have any tips or tricks to get better camera results? Both for video and photo.
I know the camera on the back is 4MP but maybe there are ways to get better pictures and video.
Thanks in advance.
This may help
Duo camera works fine on SROM. But Duo doesn't make the photos "better", it just enables the Duo effects like Ufocus, or Dimension Plus.
Hard to know what you mean by "better" unless you can be more specific. What exactly don't you like about the pics you've taken so far? Are they blurry, colors look off, too much glare, etc.?
Number of MP has little to do with image quality, especially if you are currently judging the images on the phone's screen (although cropping the pics, or looking at the pics on a monitor is a different story).
While more recent phones make it easier to take a good photo, very decent pics are quite possible on the M8. A lot can be done with technique. Despite what many folks would like to believe, a lot of photography is dependent on practice and technique, rather than hardware. A few tips:
1) Manually focus on a point (your subject) by tapping on the screen, and then press the capture button. Same goes with video. The video recording often has a tough time focusing on the subject automatically, so its often a good idea to force the focus first, then start recording.
2) Exposure (amount of light) will often change drastically, depending on the point of focus. So again, experiment by tapping on the screen, and you will see the image get lighter or darker.
3) This camera has a tough time with glare (washes out the whole frame), especially sunlight through a window, outdoors in the suns direction, etc. Changing your position, and what way the camera is facing can often (although not always) solve the problem, or at least improve it.
4) Tap on the camera settings, and see if manually forcing any of the parameters results in pics more to your liking. Although to be honest, I use the auto settings 99% of the time. But you can often get better results in certain situations (such as low light or night photos) by manually tweaking the settings. In particular, adjusting the exposure (EV) or saturation ("gear" icon>Image adjustments) may yield results more to your preference, if you find those default settings are not to your liking.
Hi all,
Me again. I made the switch from my Pixel 2 XL and for the most part, I'm in love. The camera, however, is leaving a lot to be desired. Colors are oversaturated and blown out, details are blurry or too smooth (my cat just looks like a lump of jelly), and the selfie camera, in video mode, did the attached while at a restaurant with a blue neon behind the bar (attached are screenshots).
What settings need to be changed? The camera hardware is obviously superior on this phone as compared to the P2XL but I just can't get a handle on how to make things look right.
Thanks!
As for the frontal camera, I never use it, so I wouldn' t know, but, for the main camera, I avoid using the "beauty" setting, and, the scene optimizer sometimes yields good results, sometimes not, apart from that, overall, the pictures are almost always excellent
Yeah, the weird lighting glitches are independent of Beauty Mode and Scene Optimizer, which I leave off. I've also turned off HDR, which seems to have helped a bit. The photos in daylight are nice, but as soon as it starts getting darker I lose all detail, with or without any of those settings turned on.

I suggest that you post in the thread linked below.

I would like to hear some opinions on this. I noticed some time ago that my videos had very inconsistent colors - there would be visible change of the balance when paning around or filming different objects to an extent that seems odd. After trying out and comparing I did realise that the main camera tends to very aggresively change the auto white balance, even if the scene is basically the same and the phone just slightly changes angle. It seems as it tries to desperately match white balance to every frame and its content (forgive my amateur vocabulary here), which to me seems strange and looking at other phones they just hold a much more consistent balance.
I attach 2 videos to show the issue - keep in mind that the issue isnt as visible always, as I tried very specific scenes/angles to show it.
When I use manual white balance it works great, so it kinda feels like a software issue (?)
Does anybody have a similar experience?
Would you mind trying to film a video in a similar scenario, but after disabling the option "scene optimizer" in the camera settings? I don't know if it does anything, but might be worth trying.

Thanks for the tipp, I'll try to compare it, although I dont think that scene optimizer affects videos
Unfortunately turning scene optimizer off doesnt change it (video attached).
It still feels like a software issue, but since nobody has yet confirmed a similar experience I'm starting to think it might be a problem with my unit. (Btw my A52s seems to have the Samsung image sensor not the Sony one)
Edit: or, I am exaggerating and this behaviour is actually not unusual - havent had a Samsung phone for a few years before my A52s

I do not shoot a lot of video, but in the few videos I did shoot I never saw what is visible in your videos (Sony sensor). It is indeed very jarring. Do you only have it with footage of grass or just always?
In the Samsung camera app, you can go the "Professional Video" mode in the "More" section (so where macro etc. is), and then set whitebalance manually to e.g. 5500K and see whether it is more stable then. But like I said I do not shoot a lot of video, so I certainly do not have experience with that professional video mode.
Edit: I now see that you already mention manual whitebalance yourself. So are there disadvantages to just using professional video mode all the time then?

It definitely gets more visible in outside scenes, more so if there is a lot of green in the frame - indoors and with artificial light it definitely is hard to spot. As I mentioned above it feels like it tries to match the balance to the content or objects of/in the frame, instead of keeping a consistent balance. I had a video where I stuck my hand in and out of the frame and it would drastically change the whole color to match the hand it seemed (thinking about it, the background was grass also, so ...).
Pro mode is a solution, it's just that I'm not a fan of setting the balance everytime I take a video or photo - and the balance ofc affects photos in the same way, as 2 photos of basically the same scene might have drastically different WB.
Nevertheless thanks a lot for your input - I also very much enjoyed your detailed instructions for Gcam usage

You would not have to set it every time (probably). In the Samsung camera app I have dragged the Pro Photo (not video) mode to the 'main bar' (from the more menu you can hold and drag items in and out of the main bar for quick access), with a changed fixed ISO (for shooting of fast action scenes), and you set it once and the camera app will remember that setting forever. And I think for all outside scenes around 5600K WB will work fine (it's not like the A52s is a high quality video machine anyway).
I didn't want to bring up gcam because I had no idea whether that would make a difference, but now that you brought it up, does that have the same whitebalance issues for you (in video)?

I meant I would have to set it again for every scene, but you are right, something like 5600 would probably be okay for most outdoor stuff. And with rearranging the icons it wouldnt be such a hassle. I'll try that out for daily use, thanks!
I am using BSG gcam also, because I find the nightmode drastically better but unfortunately the balance issue is the same, so I guess the balance gets set on system level. I also tried gcam awb but it always seems to be a bit off no matter the config - but I prefer the stock app for daylight anyway (apart from the wb)
