Improve low light photos/videos - Sony Xperia XZ Premium Questions & Answers

I think this will improve low light quality on our XZP:
https://youtu.be/dz4XoC7ncAI
I had compared xzp with xz2 and xz2 has clear glass on those 3 sensors... Xzp has paint over those 3... one is laser, the other 2 i don't know
We know the phones uses same camera sensors pack, but on XZP the 3 sensors are covered with paint, while on XZ2 it's clear glass.
If anyone has broken back glass, please test if low light photos improve in quality.

the xz2 has better pics not because of this, but because of better software optimizations and better camera algorithms, as you can see in the video clearly, the guy just trimmed around the sensors because nothing is besides glass on them, I mean why would a successful company like sony place them sensors and then cover them? it makes no sense...
just pray sony will release the camera software on the XZ2 for our xzp

One sensor is for laser, one for infrared, and the third i don't know. But the ir sensor is responsible for low light. Xzp has paint over ir sensor, xz2 has not. You judge for yourself ... Also camera software can improve... but i think the software difference is for 4k hdr and 1080 slow motion, not for photo processing...

you could be right, the small sensors on the xz2 (the ones below the flash and the white dot) are showing clearly, on the XZP there seems to be black shadow paint covering them but if it really makes a difference why would sony place that paint tent there? and the video you provided, the guy didnt peel the paint off the sensor just around it...

10MP Camera Hack?

http://forum.xda-developers.com/showthread.php?t=562109
What is the deal with this? Is there going to be a hack that lets the camera do 10MP?
I've not heard/seen that anywhere, nor can I really understand how that's possible, but perhaps that person has gotten confused with this REG edit?
http://forum.xda-developers.com/showthread.php?t=467616
if i'm not mistaking that has to do with the panoramic mode.
Unless they're talking about software extrapolation of the pixels I don't see it being at all possible. If they stuck a cmos/ccd sensor in that phone that had 10mp it would be a 10mp camera phone. I see no reason to spend the added cost of using a 10mp sensor and then limiting it to only 3.2mp.
Besides. If it was a 10mp sensor I guarantee you won't like the image quality compared to a 3.2mp sensor. Having no flash what so ever on the touch pro, anything that isn't direct sunlight would look horrible, if at all usable. Cramming 10mp in a sensor that's about a centimeter square or less would give very poor performance.

Does the Xperia XZ Premium camera has OIS or EIS?

From what I know, the IMX400 sensor has Steady Shot and something called Gyro Image Stabilization. But are those features hardware based (OIS), or software based (EIS)?
Its something like hybrid
No phone from Sony had OIS yet. Stabilization is software only, hence the poor low light performance when handheld.
As far as I know EIS only works in Video mode, I could not find it in auto/manual mode.
After watching this video it seems that the vertical axis has mechanical stabilization while the other 4 axis are digital stabilized. So it is likely to have hybrid stabilization.

Its just EIS on the sony i thought, the S8 has both and this phone blows that away. https://www.youtube.com/watch?v=9sV9Y2kBPr0 go to 3:13-3:44

Video quality

Your friends are never going to believe what you did. The only way to prove it to them is with that video you took. Rate this thread to express how videos shot on the Huawei P10 Plus come out. A higher rating indicates that videos are smooth (and not choppy) and that auto-focus works very well, and that the camera adjusts quickly to different lighting conditions while recording.
Then, drop a comment if you have anything to add!
The quality of video is quite good. It doesn't match up with modern mirrorless cameras, but Leica optics does hand a great value to video quality. This is exactly why I'm so frustrated on the software. Camera on itself is awesome and the quality is top notch, yet deficiency of the camera application renders camera almost useless. Except for the selfie, monochrome and pro-mode parts (which are photography modes) Too bad, video is the worst part of the camera. Only in perfect conditions it will perform quite well, but at least here in Finland Sun doesn't shine around the clock. When using artificial lighting, shutter flickering happens about 80% of time because one can not lock down the shutter speed to match frequency of said lighting. And on normal-to-low light situations, noise and artifacts destroys the video quality to a point you don't ever want to use the phone for video.
video quality is very bad. to the point that i dont like shooting with it anymore. camera is bad as well. it is very frustrating. i swapped out my iphone 6s for this huawei p10 more because i was attracted with the leica branding. and i am regretting it.. it has been 3 months already since i bought this. 2 months of selling it and no body is buying this thing

lol,i'm the same,camera was better on my note 4
Well,
is there a place where one can see other phone's videos, for comparison?
Except gsmarena.

Best photo resolution

Hi everyone!
Which resolution do you use, 12 mpx or 20 mpx? 12mpx gives you hybrid zoom x2 but phone only uses rgb lens, while 20mpx supposedly uses both lenses to create a hybrid colour/b&w pic. So which do you use? I have it on 12mpx in order to use zoom but don't really know which is best.
Cheers!
It actually depends on your preference and the situation you want to create in the photo. I use the 20mp when shooting wide angle landscapes, while im using the 12mp when shooting portraits or closeups

Thanks for replying! I've actually found that shooting a normal close up pic on 12mpx shoots in kind of a wide-angle effect. Last friday celebrating carnival at school, I was able to fit in a whole class of 28 kids from a few feet away. If u look at the pic, it looks like it has been shot on a wide-angle lens!
Any more opinions on camera config are more than welcome!
I don't believe that the 20MPx option uses both cameras. When you partially cover the B&W sensor, there is no noticable effect on the photo. Looks like it is only software based up-scaling and may get you jagged edges sometimes. After some testing with 20MPx and then 20MPx resized to 12MPx just for comparison, I prefer the 12MPx default setting.

Hi Marian, thanks for your reply!
So on a phone with a dual camera, what would be the purpose of the dual lens?? If one is rgb and the other monocrome, don't they both work together to provide depth information and zoom? Or do all colour pics use just the one rgb lens and the other is exclusively for b&w pics?? Seems a little pointless to me...
You are totally right about the sw upscale to 20mp as any other camera app only detects a maximum resolution of 12 mp, but it seems strange to me that even on 12mp colour pictutes, the phone wouldn't use both lens (depth and zoom) because the inferior P20 Lite precisely doess that on all the reviews I read about it (I've always thought that was the point of all dual-lens cameras).
Cheers!
The B&W sensor should provide depth information. You can try different camera modes and cover the B&W sensor. The phone says "Please do not cover the lenses." in some camera modes. But if you don't put finger too close, nothing happens. I can't tell it does anything at all to the image quality which seems strange. Did they made some mistake in latest build? It only does have some effect on aperture mode when you can see heat haze effect on display. It sucks we don't have more options like jpg quality or sliders for post-process filters.

Ultra-wide angle camera color science is off?

Apart from the frustrating fact that you can't record video and that the ultra-wide lens isn't very wide, the colors and seem to be extremely off in the comparisons I've seen to the point that I don't know if it's solvable through a software update. Maybe fixing the distortion and the super low saturation through software will somewhat save it, I don't know. Heck, even Mi 9 has a clearly superior ultra-wide WITH recording. What do you think? Does anyone that has the phone have a different experience? I want to buy this phone, but at this point in my country it's about the same price as a S10+ (Exynos) and I'm struggling to make a decision.
I wish GCam mods come early to save this mess.

I cannot answer specifically to the 7 Pro, but I can tell you that the colour science is off on my now-sold Galaxy S10 Plus Exynos version. Switching between the main lens and the wide angle lens in the same exact lighting and spot yields different colour reproduction. It might be down to the actual lens used in junction with the software, but I can safety say that this problem isn't exclusive to the 7 Pro if anything.
Also, don't buy the Exynos version of the S10. It has garbage battery life, and has different camera lenses to the SD version that have shown to be inferior to the SD version.
There is a setting in the camera called "Ultra Wide Lens Correction." I wonder if testers are switching this setting to see if this is the issue. I just got mine, but it's night time right now so I will need some time to test (but I only have the LG G7 ThinQ to compare to.)

Yes, but at least every other wide angle camera in the market gives decent results. 7 Pro's results are very undersaturated, very soft and sometimes seem like out of focus.
I know about the S10+. If it was a Snapdragon version I would have already bought it.

Great! Post some samples when you can. I'm not that worried about the lens correction, I don't mind the distortion. My problem is mainly the saturation and softness of detail. If you can, post original results + "corrected" versions using Snapseed/Photoshop to check if some post-processing saves the day at least. Thank you in advance!

Beauty of OnePlus and this wonderful community is the fact that there'll be GCam for it very soon, and we'll undoubtedly be able to take amazing shots through GCam using the wide angle lens.

It really depends. It might not be fixable with gcam.
The main camera uses a pretty good sensor. But it is a different sensor for the wide angle lens. So the quality of the wide angle shots will heavily depend on the quality of the sensor they use for their wide angle lens. It might be a weak sensor, we don't know right now. Huawei uses 4 Sony sensors for example, their wide angle pictures are pretty good. And yes, the best hardware is useless without a good software. But the best software also can't fix a bad sensor.
Not saying that it is a bad sensor, it's just that we don't know by now. We might have to wait for a teardown and some talented devs to see what is inside and if it is fixable.
I can only link you the specs from dxomark:
Primary: 48Mp Sony IMX586 sensor (12Mp output size), 26mm-equivalent lens with f/1.6 aperture and OIS
Ultra-wide: 16Mp sensor, 17mm-equivalent lens with f/2.2 aperture
Telephoto: 8Mp sensor, 78mm-equivalent lens with f/2.4 aperture and OIS
