Hi,
I am curious to know if anyone has tried comparison between superior auto and manual 20.7MP
Superior auto takes 8MP photos only using 20.7MP sensor...so which is best way to get best quality resolution and maximum size of photos?
Please share your thoughts and ideas.

the number of MegaPixel is not that important for quality of pictures
the image saving process is more important about it
and Auto Mode suppose to set best setting for scenes But sometimes setting manually is better
i always prefer manual mode
:good:
in 20.7 mode the ISO 12800 will be gone... Don't forget this dude
I have purchased a Lumia 1520 , because it is greater than 1 inch , the Lumia 930 , which has a knowledge. I knew that the 1520 has the same camera as the 930. And the PureView camera it was me.
Now I found out that the 930 has a much more extensive camera . Things that only have the 930 pureview camera, and not at the 1520 device: autofocus, smile detection , Scene , Exposure Compensation , night mode , continues autofocus , video calling and video sharing .
How can i extract the camera main app from the 930 and place / port this into the 1520? Both camera's are technical the same. Why not this software options?
They have absolutely the same system app (provided your OS is the same, the latest) for the camera!
Check which camera app is launched as a default.
Also remember to update both OS ( to Windows 10 Mobile ) and that camera app.
I set the Store to auto-update the apps.
You may also look for other camera apps in the Store.
Hi,
decided to start a thread hoping for somebody can help to resolve the issue since xiaomi doesn't submit it as a bug.
Only few of MIUI forum users submit the bug of low FPS video recording - http://en.miui.com/thread-182997-1-1.html You can find there links to videos shared on youtube.
The issue is that when you shoot video HDR off with rear camera on 4K, FullHD, HD modes on DEV ROM you will have video with extremely low FPS (20max on sunny day and 10max in low light scenes). However if you turn on HDR option the FPS is fine at any mode - 30FPS as it should be.
Stable ROM which is 5.0.2. Android has no issue - 30FPS at every camera mod.
So what I tried to do:
1. Clean install (delete everything) and flash China DEV ROM via MiFlash/FASTBOOT - no result.
2. Tried different Camera apps like MX, OpenCamera, Google Camera - no result. Though some of apps show progress - Instagram built-in video mode, lgcamera (but quality is crappy) but they are not very usefull apps for video shooting.
3. Tried to tweak build.prop and media_profiles.xml - no result (some tweaks caused Camera crashes).
4. Tried to change MIUICamera.apk and camera.msm8994.so from MIUI Stable 5.0.2 Android - no result (Camera doesn't work).
Any ideas please?
I'm wondering why nobody cares and not too many users confirm that bug. Nobody shoots the video with Mi Note Pro? Really? It is impossible not to notice such choppy scenes.
Tried to replace camera.msm8994.so file with a file from OP2 (which has the same CPU and camera unit) - no result as well.
Futhermore, OP2 file size is 0.59Mb and Xiaomi file size is 2.62Mb.
News about this bug? It's very annoying...and I don't know why HDR mode makes better FPS, maybe because it decreases the camera exposure, infact images are darker...surprising nobody talks about it and fix it...maybe with kernel source release we will move to a new great ROM

Meizu Camera: ~22 fps (Full HD), quality ~ 3,5/5, bit rate ~ 2,2Mbps.
Stock Camera: ~14 fps (FullHD), quality ~ 4/5 bit (program more sharped), bit rate ~ 1,8 Mbps.
Camera API: ~16 fps (FullHD), quality ~ 4,5/5 (no program sharp), bit rate ~ 5,2 Mbps!
Camera API, 4K (4096x2160), bit rate ~ 5,2 Mbps, but more detail with noise, quality 5/5! ~ 16 fps.
In Stock camera 4K = FullHD, quality, fps very poor.
In Mi Note Pro great sensor's, but software is poor.
Front camera work good, but not smooth ~ 23 fps. And not smooth auto exposition.
Thanks what to do with these camera apk? Are they better from stock? Have to put in system folder with root or just install?

Just install
Note: on 7.3.1.0 stable firmware, no problem with fps in rear camera.
Same problem
I also tried to change my low fps problem on redmi note 3g. I tried many roms, flash zips, build. Prop & init.d editing but nothing was happened. I'm feeling jealous when seeing my friends cams. Pls pls help me to solve this. Thanks in advance..
The pro mode on the nokia 7 plus is not really pro. It has limited options. I tried all the apps in playstore but didnt find anything and my 3 years old huawei has more settings in photo and video. Ishere another camera app/port that supports slower shutter speed?

Try ProShot
Why 3rd party camera apps have limited low shutter speed? Example open camera only 0,3s vs stock camera 4s.
I found out that 108 MP mode only works with ISO <=100 on the Redmi note 10 pro.
Attached are crops from 108MP with ISO 100, 108 and 125. It is clear that after SO 100 the quality drops significantly. I shot the photo in 12MP as well and upscaled the photo in the PC. The resulting picture corresponded to the 108 and 125 ISO.
It would be nice to shoot 108MP at least up to ISO 400 or 800.
Moreover it seems that sometimes the 108MP is fake even though the iso is below 100. I did not find the cause of that yet.
Finally, the 108MP photos often have a green cast. It would be nice if that could be fixed as well.
The ISO_100_cr photo has a lot higher quality than ISO_125_cr and s_1_400_cr photos.
The ISO_100_a and ISO_100_b are taken about 3 minutes appart using the same settings and the same lightning conditions. However one of them uses the fake 108MP. I have no explanation for that so far.
I reported the bug using the Xiaomi Services & feedback. So far I did not get a reply.

Use pro mode. Its there.
In all of the photos above I used the pro mode. Otherwise I would not be able to set ISO manually. However the issue is in both normal and pro mode.
The phone acts like using 108MP, but in some cases it indeed used 108MP, in other it just upscales the 12MP photo.
Try clearing system cache and cam data.
Try rolling cam back to factory load if it's been updated.

I do not think the cam itself got updated, just the system to 12.0.10 MIUI Global. I cleared all the caches and the issue persists. Using pro mode 108MP with fixed ISO 100 and 125 there is a huge drop in quality in the 125 ISO.

What about using it in ISO 200?
The drop in image Q is very small or should be.

The pictures look almost the same for ISO 50-100. Then there is a sharp drop in quality and than the pictures are almost the same for ISO 125-500. ISO 1000 is noticeably softer, but that is to be expected.

If it's native ISO is 100, don't drop below that unless the ambient light is too bright.
Use at it's native ISO # or higher whenever possible. Its native ISO is probably 100 but never assume...

The automatic mode tries to use ISO 50 if there is enough light, so I guess that is the native ISO. However that does not solve the issue that for ISO > 100 the photo looks suspiciously similar to what I get when I shoot 12 MP and upscale the picture in the pc. And unfortunately even for <=100 it is not guaranteed to shoot the true 108 MP.

You need to see what its native ISO is speced at to know.
Poor focus* and cam shake can be factors.
The 108 MP file size should be significantly larger than the 12 MP one.
*the wrong AF lock on point can trash images taken with a fast lense; the focal range is quit narrow at close range. Try some shots at 50 feet out.
All the photos mentioned above are at least 50 feet away and all have shutter time 1/300 or faster, so shake should not be an issue. The two last photos with the cherry tree even have ~1/1700s time and the issue is still visible.
Finally the picture size of the real 108MP files is 23-25MB, whereas the picture size of the faked ones is 14-18MB. Even there there seems to be something wrong.

Size of the file varies by the content, sometimes drastically. It still could be an AF issue, try manual focus if you have that option.
Cam shake can happen at almost any shutter setting; brace the cam on something solid.
Because there is no weight to the phone compared to 2-7 pounds of a pro- cam means little inertia to over come and no good handholds... cam shake is more an issue.
You can get cam shake at 1/1000 @Sec with a pro cam if your technique is sloppy.
Review the cam settings carefully and double check them.
I don't know, you could be right. It seems like it be a poor business plan though. It may be an inadvertent flaw on that production run and/or the firmware for it.

Just to be sure I did the test again using a tripod and a self timer. Still the same results. I could not use the manual focus mode, because the "infinity" seems to be only a few feet and my objects came out blurry.
The file difference was on the same scene, taken 10s apart. 24MB real 108MB, 14MB faked 108MB.
I have taken several photos in 108 in low light and the behavior of the Iso is correct.
It always maintains 108 and the Iso obtained go from 581 to 12800, I suppose it can go up a little more.
Logically, the higher the iso, the lower the quality and more with such small objectives.
I am very happy with the camera results and I come from a Pixel 2.
Well for one thing use solid objects that aren't able to be moved by the wind as subjects preferably with the light source in back of you rather than in back of the subject.
A wrought iron fence maybe.
24 mp is actually a lot. It's not just the pixel count but also the quality, grey depth, color accuracy that the individual pixel can capture.

I selected branches because there the difference was the most obvious. There was no wind at all. I attach different part of the picture with a solid object.

The camera reports all of the 108MP photos to be 108MP. However I believe that sometimes the picture was taken using 12MP and then just upscaled to 108MP using a software.
Good obsevation. I can't get my phone to make 20+mb pictures. I tried with your setting so: 108MP & iso 50 but no luck. Photos still come out between 14-17mb.

Sometimes I get the fake 108MP even with small ISO. I don't understand that. Or maybe your scene is not that complex and the file is smaller even though it is the real 108MP. Try using ISO 125 if you see a size and quality difference. You can also try shooting 12MP and upscaling the picture in PC to see if it is the same as what you shot in 108MP.

MP=megapixels
MB=megabytes
The correlation between file size and the number of megapixels is a not strictly a ratiometric one.
Without the manufacturer's white papers it's hard to know exactly how they are processing the image. Companies like Canon and Denon usually exceed their specifications, and often share detailed information beyond just the specs.
♤Does the cam allow you to shoot in RAW mode?
Try that if so. That should give a more revealing look at what's going on. RAW's have the least post processing and contain much more of the image data.
