Low light - Xiaomi Mi 5 Real Life Review

At the club, at the bar, or just in your mom's basement, nighttime is when you come out to play. Rate this thread to express how the Xiaomi Mi 5's camera performs when no or low light is present. A higher rating indicates that the camera sensor "sees" lots of light in dim conditions, and that the resulting photos have minimal noise. A higher rating also indicates that when the flash fires, the resulting photo is evenly-lit without any bright spots.
Then, drop a comment if you have anything to add!

It is so many noises even Mi5 has OIS and f/2.0 and a good sensor in general

Auto is no good for low light, use HHT, always.

Has night mode improved at all with new firmwares?

I dont get the hate for the Mi5 camera, imho its better than most flagships too even in low light(I know it is a flagship but at 1/2 - 1/3 rd the cost of most flagships,its truly amazing)

the aperture is actually lower than stated. i think it is at most f/2.8 or lower. compare to another real f/2 phone in the same environment it will tell.

In terms of darkness or bokeh, cause low-light most likely has to do with shutter speed, maybe Xiaomi put higher iso to combat blur then applies noise reduction.

Assuming the EXIF data doesn't lie, it's indeed f/2.0.

Average.

the auto mode of this phone's camera is not as expected, the shutter speed almost as-if locked at 1/8 on low light (auto mode). but the manual mode tells a whole different story, i really like the manual mode of this phone

This or the Honor 8...?
Can anyone answer a few questions about this phone for me?
1. Would it work properly with T-Mobile?
2. Could I install the Google Camera app and be able to do Photospheres?
3. How does this camera compare to the Honor 8's camera? I know spec-wise, but real world performance?

.....sony camera..... opticalstab.

Almost can't tell the difference when using the flash or not (in a good way). Surprisingly impressed!
Comparable to my iPhone 6 Plus. Colors are more saturated like a Samsung but overall great camera.
I had a birthday party I went to today and it was in a low light situation. The HDR+ photos came out very good to me.
Where my Note 4 camera failed to perform in very low light conditions, the nexus 6p impressed!
Compared to my HTC M8, which took okay lowlight pictures, the 6P blows it out of the water. And with more detail obviously!

Amazing what the larger pixals do. Took a picture in some pretty low light. And the image processing combined with the larger pixals. Made the picture not only brighter but crisper.
Great camera! Still not quite as good as this year's Samsungs but overall very nice

In low light conditions, I paired it against Oneplus One and LG G2 (with Xcamera). Even though the resulting images came out with pretty much the same brightness level of images, Nexus 6P however produced greater details as compared to other photos from other phones. So I would say camera on Nexus 6p is good.
works very well

low light shots are amazing on this camera. Look at this one I took the other night. You can see so much details, amazing for a smartphone.
Great low light performance, no flash just HDR and captured clouds almost clearer than my eye could! I do like this camera....

I also used to have an m8 and I thought that camera took the best low light photos of all time....until this phone. The low light resolution is amazing!
Absolutely LOVE this camera.
overall quality is much better than note5 or iphone 6 in low light condition

Noise clearly visible, even at reduced resolution (the forum automatically resized the JPG file to 3 megapixels). But HDR is pretty good. Also good job on the white balance: getting the bright red light imaged correctly is probably a major challenge for many cameras. Comes out very true-to-life on this shot.

I posted a link to my picture folder I have on google photos under the main picture section of The Real Life Review section. There are some low light photos in there that compare the normal google camera on the pixel to the manual FV-5 app in low light. I have to admit I am throughly surprised by how well it does in low light. Usually you'd need OIS in order to compensate your hand shake for lower light photos to turn out. Using the normal google camera the super low light photos pretty much sucked. But using manual modes through FV-5 I got it to .5 second shutter open (The highest you can set it) and up to 10k ISO. I know 10k is insanely high but when the shutter won't stay open for more than .5 seconds even on manual, you need a higher ISO to compensate. And it allows just as much light in as my LG G5 did on 20 second manual mode. Mind you, the 20 second manual mode at 800 ISO is going to be MUCH MUCH less grainy than on the Pixel.
But the fact the pixel can get the colors right and show so much detail in .5 seconds is nuts. I'm attaching the Google Camera App low light photo and the one for the FV-5 manual photo
There's a bit more noise than what I would prefer, but the colours and brightness are phenomenal.
I was just going to post a question on this. This is the same picture, my front porch, dim porch light behind me. No flash and flash. I reproduced the effect several times. I'm probably going to try and return the phone tomorrow in hopes it's hardware. If other people have the same results though......

There's so much noise because the ISO was boosted to an obscenely high 10k. A third party camera app with manual controls had to be used to achieve that, because no automatic mode would ever go to such a high light sensitivity.
Edit for additional elaboration: I say this because the way you've worded your post leaves ambiguity in terms of whether you're blaming the phone itself for the presence of noise
It's a decent low light performer. Although the lack of OIS shows sometimes if you don't have a steady hand.
I wanted to try low light so I went out of my way to try the camera in a few cheesy museums in Niagara Falls. They were very dark and my flash on went off once. The pictures were great.
Mine is terrible. I get random colors, either washed out white or green. Nothing intelligible in the pics. If I snap the same shot every time I will eventually get a clear one. It's like the sync between flash/shutter is off on most of the pictures.
Can't seem to focus
Did some testing with the XL and the S7 edge seeing a live band and while the XL kickass in daylight, the edge won hands down when it comes to taking pics inside low light....XL produced grainy, slightly blurred pics...XL was set to 16:9 8m and the Edge was set to 16:9 9.1m.....I still love my XL though

Really? In auto-mode? Currently I´ve testing both phones. The S7 really sucks in auto-mode in low light, but with manual controls I can produce better or sharper shots than with the pixel.

Nice comment.. because I like to buy a s7 edge or pixel xl and.. I still undecided.
tried to up load pics but files are too big and i get a error
6:15 am... Some artifacts, but most phones wouldn't have shown anything.
From what i've seen I have yet to be that impressed with low light shots.... i still have one a XL on order, I don't get why google yet again left OIS out. Its not like they were trying to keep the price down this time.
nice !

Probably requires a little work on the SW, as I've noticed it takes great pictures at times, and then bad pictures in the same conditions at times. Misses one star for low light pictures.
I deduct 3 star for low light, EIS doesn't work in still image & there is no OIS in OP5 (OP5 downgraded from op3 in stabilization) so, in pro mode it's impossible to use 30s long shot without tripod or stands(who the hell like to use tripod in smartphone).
And the normal shots has lots of visible noises compared to advertised, portrait mode doesn't work in low light with flash, (missing on background lights bokeh), telephoto lens which is only 1.5x optical doesn't work in low light.

It's great to my untrained eyes. XD

Now I ordered a tripod from Amazon, and a separate smartphone holder. I already got a Bluetooth remote that can be used as remote shutter.
If you are experienced photographer or using OP5. can you tell me what setup would be the best to take photos of half moon with lots of patterned light clouds, I tried to take photo of that and the Moon is all blured out to a round bright circle, I tried on different iso and shutter speed, with focus on that landscape sign ...
I'm very impressed with the low light quality of this camera.

Yes, I provide here the link for the photos.
These are a set of night pictures, all taken in the same place with a tripod and different settings. This was my first test with a lot of different manual settings.
In every picture taken there's the apperture, the shutter time and the ISO in the details.
You can see for yourself which settings took the best pictures.
Remember this was complete night time with just a few street lights.
The download is pretty big, 427MB but they are the originals with the respective RAW files.

Noobs help for manual camera

Hi guys I've just come back to the xzp from my note 8 (hate all the bezeless trend) and the pictures on the xzp are quite noisy especially in low light
I've heard that manual mode is the best but I'm a noob when it comes to manual setting in the camera app
What's a good starting point for the settings in manual mode to get me started with better pics in low light
I don't me night time pics just room lighting types lol
Thanks
Anyone have any recommendations :laugh:
It's easy, lower ISO better quality (but less light). You can compensate the low light by decreasing shutter speed, but then, you have to have a really steady hands, or tripod.
So, in short, to get the best quality, use ISO50 and shutter speed 1s. However, without a tripod, it's really hard to get sharp photo. Sometimes when handheld, you can try shutter speed 1/8s with higher ISO (200 or 400) you will see what is necessary by the brightness in viewfinder.

I think that's just a consequence of Sony's extreme post-processing, along with the the lack of OIS and the longer shutter speeds. When zooming in you'd notice that most detail is wiped out by the post processing even in good lighting conditions. As far as I know this can't be fixed since Sony doesn't give raw files and third party cameras are worse.
If you're using 1s shutter time then it's easy to get a bit of blur from the phone moving if you're holding it by hand but it should definitely has less noise than auto.. Resting it against a surface also helps. I found it better to use the on screen shutter button rather than the physical shutter button to reduce shaking, especially if you're using a case.
But in regards to high noise in room lighting, I find that a bit odd as the pictures I took were pretty clean, at least compared to similar cameras like the OnePlus 3. Maybe you're just noticing it because you came from the Note8, which possibly has the best camera?

It's because of hand shake when taking picture. Bidiminished said one more important thing I forgot, set a self-timer for 3 sec, because it's very easy to introduce slight movement with button press or even on screen touch.
Also, having a mobile tripod is a huge help if you can use it at the moment of taking picture.
Some example, cheap tripod with lenses(lenses are not that useful, but the tripod in this set is good ) for 3,5$ with free shipping.

Still room for more improvement in Essential's monochrome camera? How does P20 do it?

So as seen on dxomark , the Huawei P20 pro is now the king of phone cameras, and one key thing is that it has a second monochrome camera just like the essential. Perhaps they figured out how better to "utilize" the monochrome camera much better than the devs at Essential?
i love my essential and i think is hope that it can be even better!

There are a lot of ways to use the monochrome camera.
You can possibly use the image for increased dynamic range or contrast.
I use the Google Camera port for most shots, and use the OEM camera for B/W shots, which it does very well.

How do they do it? Better hardware that's how
I don't think the way Huawei incorporates both cameras is better hardware, it's much better software. Huawei uses what they have better.

The hardware itself, i.e. the cameras, are better quality. We can argue this all day, but you can only polish a turd so much (fix poor quality hardware with software)
The P20 Pro takes amazing pictures because Huawei put an amazing primary sensor (and lenses) in the phone along with good image processing.
GCam demonstrates the limit of image processing (taking low-light images being more detailed than the monochrome camera on the stock app) but without better camera hardware that's as far as this phone can go.
What better hardware? The P20 can get about 50% more light per pixel which is half a stop which amounts to nothing in the photography world. DSLR sensors gather 10 times or more light than phone cams and yet DSRLs are dying.
In the smartphone camera world, software is everything. Remember that the LG G6 has the same sensors as the PH-1 and yet its DXO scores for texture and noise are way higher than both the P20 and the Pixel 2. And that's the scores for just a single sensor. The Xiaomi 5s also has the same sensor pair in the same arrangement as the PH-1 and the combined output trounces any single sensor in the smartphone world.
Essential is really behind in their software department, notwithstanding their commitment in software support. Despite of the fact the camera designer was the one behind the iPhone's portrait mode, their software still can't live up to hardware potential. The current stock cam app, even with combined sensor output, can't come close to some GCam mods which use just a single sensor.
---------- Post added at 12:08 AM ---------- Previous post was at 12:03 AM ----------
The P20 Pro, on the other hand, got the good low light quality only in 10MP mode which pixel-bins the 40MP down to 10MP. Its texture and noise scores are still no better the than the G6. At 40MP its low light quality is worse than crap.
Yeah no.
You can't go using "it's nothing compared to DSLR's" when the difference is 50% more light per pixel. DSLR's are not dying because of quality but because it's convenient to have a good enough camera in your phone.
Obviously software is the key for modern cellphone imagery, that isn't even the point here. We already know what better processing does for the Essential sensor in the GCam mod. Which also works on the G6 incidentally and yields generally better results than LG's own app. But on the whole it's not nearly as good as the Pixel 2 for instance. Don't give me "but DXO said" because even G6 users don't believe they do better.

I didn't say "it's nothing compared to DSLR's" . If you don't understand, I'll say it again: 50% more light is half a stop which is nothing in the photography world. Do you even know what 50% more light means?
DSLRs have better hardware, but are dying not because of lack of convenience, but because quality from smartphone are good enough these days. Convenience was always there from the beginning of the smartphone age, but quality has only gotten good enough a few years recently. DSLRs always have the hardware advantage, but smartphone have the software and that's what make the difference.
And G6 users can't do better than Pixel 2 like DXO because they don't know what to do to get as good as DXO, at least in terms of texture and noise. "On the whole" is another matter since it's the whole package, which means Google software is much better than LG software. Well, it's the software that makes the difference. That's the point I'm making. It's not the camera hardware, it's the software. Differences in smartphone camera hardware are peanuts.
He also neglects to mention OIS on the g6.
Also, the Xiaomi Mi 5s Plus has the exact same design, with the same two Sony IMX258 sensors, one RGB and one Monochrome, no OIS, and it has the exact same problems with low light, even in daylight, and shutter lag. That phone was released a year ago. So Xiaomi proved this idea is a failure.

Since you mentioned OIS, what does OIS do to make the sensor output better, specifically texture and noise quality? If you don't know, it does exactly jack squat nothing to the sensor. It helps with the whole package, but that doesn't make people like it more than the Pixel 2.
And the Xiaomi 5s is not a failure, at least in terms of camera quality. The least you could do when trying to argue against it is to look up review results for yourself. Look at the comparison tool at GSMarena for the 5s in stereo mode compared to any other phone cam, instead of talking about something you know nothing about. People make the results and tools available and you don't even bother to look at. Sad!
Why people make unsubstantiated claims about something they don't understand or even try to learn about? Opinions can always be different, but at least have some informed opinion.

Lol you're one to talk. You don't think OIS effects low light photos? Interesting. You should do some reading. Noise levels in low light are highly related to OIS.
It is ranked about the same as essential phone by most reviewers.

Absolutely not. OIS reduces vibration from your hands to help getting sharper images. Same exposure parameters with or without OIS give exactly the same noise level. It does nothing to help noise from sensor. If you think it does, explain or cite how it does.
The effectiveness of OIS on smartphones is dubious at best due to the very short focal length on most phones. If it's really effective, those gimbals wouldn't be in high demand or that expensive. But this is another matter unrelated to the photo quality of sensor output.

"If your camera meters the need for a slow shutter speed which will cause camera shake, there are two ways to switch to a faster shutter speed:
1. Open up the aperture. Opening up the aperture (makes the hole bigger and therefore) allows more light to come in and so reduces the time the shutter needs to stay open. ["Shutter speed" is simply the time the camera keeps the shutter open.]
2. Often, especially in low-light situations, this will not even give you a fast enough shutter speed to hand hold the camera, so the second way is to use a higher ISO."
"At this slow shutter speed and without using a tripod, we will obtain a blurred image if we hand hold the camera. But, with Image Stabilization, we are now able to hand hold the camera without worrying about camera shake (1/15 sec. is 2 stops slower than 1/60 sec.).
If the light level falls further and the camera now needs an even slower shutter speed, say of 1/4 sec. (that's 4 stops slower than 1/60 sec.: 1/60 sec., 1/30 sec., 1/15 sec., 1/8 sec., 1/4 sec.), Image Stabilization will not help us eliminate camera shake in this case. It will, however, reduce its effect.
Note that IS works irrespective of the ISO used. Whereas High ISO forces you to use a high ISO (with resulting high noise and image degradation issues *1), IS allows you to keep at a low ISO while still reducing camera shake (thus keeping maximum image quality). That is, it does not mess with your selected exposure settings (you keep the shutter speed, aperture and ISO you want to use)"

Hmm, that's a lot of quote, but not sure how much you understand or believe in all that. How do you adjust any of those settings with any (except one) cam app?
Whatever exposure setting you take a picture at with OIS on, I can take another picture at the same setting with OIS off. The noise level will be exactly the same. There might be a difference in sharpness, but how much difference will depend on how firm I can hold the camera or if I use an external stabilization device or not.
Like I've said, it helps with the whole package, but it doesn't explain how the G6 get higher noise score than the Pixel 2 which also has OIS. It's all in the software.

What that user was trying to convey is OIS let's you use a slower shutter with less motion blur due to camera shake. Slower shutter equals lower ISO, which likely results in less noise. This doesn't help for moving subjects though.

That's the theory. Slower shutter speed *requires* lower ISO for the same lighting level, since the aperture is fixed. But in practice, I wouldn't give it up like that, but rather try to brace myself to reduce vibration or just use a stabilization device/tripod so I can shoot at the same exposure setting and get the same acceptable noise level.

I think you have it backwards.
A slow shutter allows you to use a low ISO.
A fast shutter requires a high ISO.
This assumes shutter an not aperture priority.
Also 1/focal length is the minimum shutter speed to not have noticeable shake at correct lighting.
I feel like this has gone a tad off topic. Not to say its completely irrelevant but I feel the starting point is, us comparing both the Ph1's and the P20 implementation to know whats different.
