I have a note 3 sm n900.
But in my camera if the turn image smart stabilisation off the photos sre taken are very fast but they start cracking if i zoom in.. if i take a pic of a book or something the words arent very clear,i even tried keeping my hands very steady while taking the photos.
On the other hand enbablimg smart stabilisation, camera takes around one second to take a photo and the photos arr very clear.
This shouldnt be happening, right?
Whats the point of having smart stabilisation off if the photos look like taken from a 2MP shooter.
Please help.
Please reply.
I have been hurt by the community as my last problems didnt even get a reply.

Are you aware of how camera sensors work?
Smart stabilization is meant to offset the use of higher ISOs/lower shutter speeds so that your pictures turn out less noisy. Given that the Note 3's max aperture is f/2.2, let's make an example.
In the daylight, your ISO can drop and thus picture quality can improve (this is very barebones, but it's for conceptual purpose). In essence, higher ISO = more noise, especially the smaller the sensor size. You can visibly see that the Note 3 has a very small sensor. In fact, even on APS-C cameras, noise performances starts to suck around ISO 3200~6400. ISO is meant to make each pixel brighter (or something to that effect), and the smaller those pixels are, the more noise you'll generate (again, not exactly, but that's the gist of what you're experiencing). So, with 13 megapixels fit onto the small sensor, you're likely going to start seeing noise at like, ISO800 (this is a random guess, but it's probably true).
Anyways, so during the daytime, there is a lot of available light, so the ISO can be reduced and exposure can be adjusted using shutter speed (assuming aperture stays the same). This improves picture quality as lower ISOs generally equate to less noise. However, as you get later into the night, less available light means that one of two things has to happen. Either your shutter speed gets slower to let in more light, or your ISO cranks up to become more sensitive to the available light (and thus more noise). Usually a combination of the two occur to get a trade off between quality and shutter speed.
A quick browse on google gave me, 1/15, f2.2, ISO 1000, as EXIF data from an iPhone 5s taking a picture at night. As you can see, the ISO is pretty high for the small sensor, and the shutter speed is quite low. As a rule of thumb, you generally want at least an equivalent shutter speed to the focal length, but given the crop factor of this lens, I have no idea what that'd actually be. But 1/15th is very, very hard to hold without some form of IS/OS, even on full-frame cameras. What you're experiencing is this effect. The low shutter speed to let in more light means that even if you breath and shift the camera 1cm, you'll get blur. It's not out of focus, but the subjects weren't in the same place because you moved, causing them to be rendered in shift. The noise is the result of the ISO being too high; the pixel sensitivity isn't that great, and so you're getting all kinds of weird colours that the phone is trying to represent without definitive data. Again, we're assuming that the aperture stays wide open under these conditions to let in the most light.
I hope you got the answer you were looking for. Basically, what you want is pretty hard to do, even with a full-framed DSLR (although it's becoming less true with recent image processing). You can't really turn of IS/OS and expect the pictures to be great. There's a lot of other things that are taken into account behind the scenes that are usually beyond your control on your phone. Smart stabilization using image processing algorithms to help mitigate the impact of higher ISOs and lower shutter speeds by post-processing the images you take on the fly. Such is the cause of the delay.
What version you're running , do you try to use any third-party camera app results may vary , did you increase exposure value, try to reser all camera setting to default

Got it sorted out. In not so bright conditions the pictures start breaking and by turning on smart stabilisation it gets fixed. Credit goes to the last persom who explained. Best explanation ever. Hats off to u

Today on my walk with the dog I was lucky enough to take a photo of him "Uwe" during run, I really like it but after back home and uploaded photo to the computer I've quickly notice there is a very bad pixelation all over the photo visible at 100% size with my 32'' 2560x1440 monitor
there is lots of hair / grass details destroyed by the huge pixels! so I am asking is this normal ??? photo was taken in HDR mode 5312x2988
there is the photo:
http://f.cl.ly/items/0P2w1W2D461i3L2E1V28/20141103_151549.jpg
and this is zip file with the original jpg taken from phone, this is probably the same as above quality but just in cast server side compression
http://cl.ly/2Q0A2M2v2C2l
This picture has to be considered excellent!
The N4 camera managed to capture the action and the focus is perfect on the dog.
Regarding your concerns, you can NEVER, and I say again, NEVER judge a smartphone (or even point&shoot) camera by looking at it on 100%.
This is because very heavy noise-reduction algorithms are applied to the picture, and this results in smearing of details when looked at 100%.
But I can assure you that if you print it as big as poster size (A3), the result will still be great!
Only cameras with big sensors can produce excellent quality at pixel level (when viewed at 100%).
So, rest assured that you own a phone with a very capable camera.
As a rule of thumb, always try to have as much light as possible in the frame, this will reduce this "smearing" effect.
I have to agree with the original poster. There's something odd going on with this camera. It's either over-compressed at higher resolutions or they're playing some kind of game to simulate a higher resolution than the camera can achieve clearly. Or maybe they have a really bad high-pass filter on these.
Also, I doubt that these will look good when printed at A3 but since I don't want to use the ink to find out, I won't argue that point.
One thing I've found is that the images are sharper and less mottled looking when I use a lower resolution. 5 or 8MP. It's also very sensitive to light levels. In typical Samsung fashion not all Note 4's are created equal. I've got the US T-Mobile SM-N910T. Other versions may behave better (or worse).
I'm putting together some comparison shots and will post when I'm finished. I've taken shots with the original Galaxy S, original HTC One and my Note 4.
A lot of my pictures look way over-sharpened.
Maybe another camera software could fix this, but I haven't played around with it yet.

Yes, HDR is known to degrade the image quality if there's a lot of movement. I only use HDR for still scenes.

I'm in a dim room.
Testing picture quality
Consistently, auto mode producing the better pic. Manual mode without any adjustments on my part is very grainy.
Checking on the details of each pic, the manual pic shows an ISO of 4k. But the auto shows an ISO of zero!
can you guys reproduce this
A) Can't reproduce.
B) Max setting accessible in ISO is 3200 according to the two camera apps I have.
C) Since you are not getting an accurate readout of the ISO, I can't comment on why one is grainier than the other.
I mean open the pic in gallery and choose details. That's where is saw I so 0
But taking a picture outside in bright daylight both pictures show ISO 100 in the detail screen. I can easily reproduce this by just dimming the lights, and again, the one taken in Auto mode has iso 0.
Ok, I had to shoot in a room way darker than I'd ever shoot with a phone to get anything to happen as far as ISO. I still have no idea how you are seeing ISO 4000. Max setting is ISO 3200. I am not seeing ISO 0, it just doesn't show an ISO listing if I'm shooting in an excessively dark area. Like I said though, I wouldn't shoot with a phone, any phone, in this kind of light. I'm not sure I'd even shoot with my 1" sensor camera. I'd probably grab my full size camera.
As far as "grain", what you're seeing is noise. That's what happens when you exceed the physics of the sensor. There's two ways to go about it. Either you live with the noise in exchange for a little more detail or use noise reduction and smooth the detail into oblivion. Auto is definitely using a lot more noise reduction and killing detail that manual isn't quite doing. Overall, the noise profile in manual is actually pretty good for such a tiny sensor at such a high ISO and it makes for a really good old school film look.
I think I vaguely remember the g2 showing ISO 0 or no ISO at all when in auto in certain situations. may be an LG thing.

Hmm..also...it seems iso 600 noise is more dots like, while 800 and 400 seems splotchy...like...wet paint. (For dimly lit images).
As for the weird iso numbers..dunno..that's what the details say
splotchy is the noise reduction. g2 had it too. we called it the oil painting look lol

I think we can all agree that the camera's auto mode can be a little weak on low light, fast moving objects, and focus.
However, I have gotten ridiculously amazing results using manual settings. To the point where I wish (if anyone from oneplus is seeing this, please please implement it) I could set up various quick-access custom manual mode presets. It would be a very good feature (does anyone know an app that has that btw?).
With a little tweaking, you can find a super sweet spot for a picture on certain conditions.
The following are examples on a very low light scenario with no image movement and minimal hand movement (exact same environment conditions on all):
- Normal mode
- Normal mode with HDR
- Normal mode with HQ
- Manual mode with ISO at 400, and shutter speed at 4s. Then touch and raise finger on screen to place exposure point, and then touch same spot and drag to place focus point.
I was shocked to see that this camera could actually capture something like that last shot in my home's corridor at 2am, when the normal modes barely gave me anything visible.
That setting is working very well for me on multiple very low light situations. Really wish we had some quick-access presets.
There are also settings which can capture images with fast moving targets (with low shutter speeds and a little higher ISOs), and usually I don't get blurry shots with focus on infinite or when selecting focus point.
Things to avoid are super high ISO's like 6400 which for some reason the normal mode is very fond of using even though on manual we can only get up to 3200.
Not sure why you would prefer blurry 4s shot over noisy high ISO shot? Yes auto mode isn't as good as the one compared to LG or Samsung flagships but even manual mode has its limitations. 1/8s is pretty much the limit of what you can shoot with OIS and that is only if you have super steady hands. Most phones with OIS can give quite good results at 1/16s and ISO 100 onwards depending on the lighting. Anything else like 1s or longer exposure and you'll need a tripod . By the way max ISO is only 3200 so you can't go higher.
Oneplus 3T noise reduction algorithm is quite bad and even at 100 ISO which should be super clean in daylight is probably one of the worst in the class.

maybe RAW is a solution here?
I have been trying Open Camera for the last couple of days. Seems to take much better low light photos. Not as good as my 6p but at least the photos dont look over processed and washed out.
Say "cheese", then rate this thread to express how photos taken with the Xiaomi Poco F1 come out. A higher rating indicates that photos offer rich color (without over-saturating), sharp detail (with all subjects in-focus), and appropriate exposure (with even lighting).
Then, drop a comment if you have anything to add!
I find the front cam can't even handle small shakes.. I need to be very careful to take a selfie. Does anyone else face this? I'm not sure if it's only my device.

Same here, you have to keep the device very still while taking pic..no EIS and OIS.. have to live with it... But camera quality is good..

Well, not really . My 6p nor my Zenfone max pro m1 had ois or eis. Both took unshaken selfies. I also checked with few others using Poco and they can't find any such issue. For me the problem is when we use volume rocker, we tend to push the phone a bit. And that shakes. I always use volume rocker and asked other Poco owners to do the same and their selfies are not shaken. I think it could be individual device's fault.

No such problem in my phone, captures stunning selfies and rear snaps without any trouble. You might have tremors.
anyone try to take a photo of the imei at the back of box, cant seem to focus well
I bought POCO F1 during 1st flash SALE. I'm not satisfied with the camera performance especially the edge detection is very poor during portrait mode..
Even though the reviewer are showing good portrait mode with better edge detection...
Can anyone help me with the settings or is there anyone else who is facing the same issue.?
Please suggest whether or not i should replace my phone..??
I agree about the camera issue with slight shakes, the default camera app can't handle it well.
Bought it in 2nd flash sale. Camera quality is below par (rear camera). Focusing issues. My 1 year old lg g6 is way better. Im not talking about OIS. But taking still pictures with default settings.
Has anyone tried different camera app?
Does any one face the issue that in Portrait mode (rear camera) the faces are too beautified and they lack details.. i mean no sharpness.
Any one knows how to solve?

So far so good, if you wan't not shaky photos, don't use volumen up or finger print, try to stay steady, don't be afraid to take more photos of same subject and delete bad ones.

So to conclude, pocophone has decent camera. In good light and in controled light it has good dynamic range, lot of details and focus is fast and accurate. In low light, noise reduction reduces amount of details, and photos can be blury due to longer exposure and lack of ois.
Solution?
GCAM
It is in earley stages of porting for poco, so give it few weeks, but already it gives better results in low light than stock camera. Best thing about it is that you don't need to root or flash anything, just install it and that is it.
Oneplus 3 with Gcam takes 12MP photos much better with sizes ranging from 6 MB to 10 MB which is a result of capturing higher details. While the poco stock cam takes 12MP photos with size less than 4MB and portrait photos are less than 1 MB. There is either compression taking place or some aggressive noise suppression that takes away all the details thus resulting in smaller file sizes. This problem exists even with the redmi note 5 with 12MP photos taking up less than 2 MB space. Can somebody else test this with their poco and see if they are able to get a higher file size?

From the stock cam, I see reasonable amounts of details in the images and file sizes range from 4-8 MB in varied conditions. I have a protraits that are around 8 MB, perhaps you may want to check the settings if there is something amiss

Ok so here are my observations. Poco's AI or auto mode uses fast shutter speed and low exposure to reduce blur and compensate for the lack of OIS.This results in loss of details. I see the oneplus 3 use slower shutter speeds and higher exposure to capture a lot more detail using its OIS. I used manual mode in Poco to mimic Oneplus's setting and took photos with 1/15 shutter speed and 800 ISO. Oneplus 3uses these settings on non hdr mode.
Oneplus captured a bit more detail but with more noise than poco with a file size of 5 MB and poco had less noise and lower details with a file size of 3 MB. These are indoor shots.So poco uses noise suppression resulting in loss of detail.
Gcam HDR mode dramatically improves image quality in oneplus 3 with higher details and lower noise with a file size of 7 MB for the same photo. Hence we can expect Gcam mod to do the same wonders for poco F1.

That's where I feel the poco stock cam does a fine job on the software to overcome the hardware limitations, for most of our normal day to day use, these pics are quite good, the dynamic range is impressive on many occasions.

I personally feel the auto mode on stock cam is very conservative on the settings resulting in an almost unusable indoor and low light shots. This can be overcome mostly by manual mode but I still feel this needs a proper gcam port to unleash the true capabilities of this sensor.

Agree on the indoor picture quality, good thing I have the Note8 for that and the low light shots
Poco is good for all day browsing, chatting, and some decent day light clicks. As a daily driver there's enough things on the phone to like it.
Does anyone have Direct experience taking pictures with a Galaxy S7 and this one? I would like to change my mobile phone but I wouldn't like to lose a lot in camera experience. Thank you very much
