Watermarks on each taken photo? - Xiaomi Redmi Note 4 Questions & Answers

Hi,
I took a few shots using GCam and found strange watermarking on uniform areas of the image - white/blue dots always forming the same pattern. I haven't tested MIUI's camera app yet.
Anyone stumbled upon this? Is this inherent to GCam?

Mine does that too, but only in GCam

[Q] Cyanogenmod 10 camera field of view

Hi. I'm using cyanogenmod 10 for almost 3 weeks . The camera which came with cm10 is showing less field what actually is.
Are the photos it saves a normal field of view? In other words is the problem only with the view in the camera app or is it with the saved photos too
Sent from my GT-I9300 using xda app-developers app
This picture is shown in the gallery. You can see my printer is in view. (left side)
Also you can see the light switch(left side) is in the view
For second picture,
But in this picture you can't see my printer and my light switch.
I didn't move the camera btw just took a screenshot then pressed the capture
Any ideas?
You can't bump a thread more than once every 24 hours
I believe this is done because of the aspect ratio of your screen and the photos your camera takes. If the photo fov were to be used in the camera, there would be black bars in the camera app. You can try using another camera app from the play store to fix this.

I'm sorry. I didn't know that . Do I have to use 3rd party camera apps. Or can developers fix this problem in next updates. And can you advise me a good 3rd party app. Thanks for your help.
Do you have photo stabilization by any chance? That does reduce the fov.
No I don't have photo stabilization.
Try an app in the store called "lg camera" from memory that's the name. It has black bars which is what you want
NO no no this is not that I wanted. Actualy when I take photos with my friends they can't be seen before shooting.so sometimes they seen out of the fov but when I take photos they are in the fov. I don't want black bars or something. I mean I want to take a photo which looks exactly same in the preview.my post which has an attachment will show my problem.

Tips to improve image quality in LineageOS using default Snap Camera

Hi,
I've recently been playing around with various cameras under LOS on the Axon 7.
I've been experimenting with Snap (built in LOS camera), Open Camera, A Better Camera and Footej Camera.
Simply installing the apps and using the default options yields the following order (best to worst):
A Better Camera
Open Camera & Footej Camera (tied 2nd place)
Snap camera
However, by tweaking some of the options in Snap camera, I've been able to get consistently better images than any of the other apps using their defaults.
To improve the quality of Snap make the following tweaks:
- Set Picture Quality to High
- Set ISO to Auto HJR
- Set Contrast to Level 6
- Set Sharpness to Level 3
- Set Auto Exposure to Centre Weighted
I've done side by side comparisons of the four apps and I've found that Snap leads the pack with the tweaked settings. As an aside, I used the app PhotoGrid to create the zoomed side by side images.
I'd be interested to hear back from others re: their experiences using the tweaks to improve image quality.
One final note, I also tried using the Axon 7 stock B04 camera on LOS, but it was consistently worse than any of he other four options so I removed it. There is a magisk module for B04 if you want to try this for yourself.
Regards,
jamesK
Here are some comparison images. For each image the apps are represented in the following order:
Footej Camera - A Better Camera
Open Camera - Snap Camera (with tweaks)
I have tried your settings and the results with snap camera were a bit better.
Because I ve used high resolution mode the differences where less significant.
I tried a comparison with axon 7 camera mod for LOS and it's quality is still the best in my opinion.
1. Snap @ high res settings
2. Snap @ your settings
3. Axon 7 camera mod (Tapatalk app bug uploads media to his own server.)

Hi,
Thank you for taking the time to test.
Your first image was noticeably better than the other two (you could see the marks on the thermometer).
Are you using B05, B04 or some other version of the LOS camera mod?
I tried the B04 magisk version of the mod but didn't find that it produced good results. Perhaps I should try B05.
Regards,
JamesK
I am using b04 Magisk by kingo.
Ive used the screenshot function on my device. Cropping images resulted in lower image quality.
I took a look on the numbers of the thermometer and on my devices screen I had the best images with zte cam.
One small note. The object is appx 3 meters away from me and the pictures were taken after tap focusing the object.

Thank you for the details. The only difference with the images I attached is that I zoomed to 100‰ on the original images.
As mentioned, when I tried this with B04, the image quality was not as good as the other camera apps.
I'll reinstall it and try again. Perhaps. I overlooked something.
Thanks again for your feedback

Working Gcam 6 with manual focus and long exposure!

Mar 12th, 2019
So it has been awhile since I tinker with Gcam, and now that I have finished the modding of it and no longer have my Mix 3, I will upload the final copy of Gcam. As usual thanks to everyone from defcomg, cstark27, san1tyy, xtreme, bsg, zoran.
https://drive.google.com/open?id=1rBUkxfz2IlG_0SGaTlJ2G6mL-16Bx8LY
Changelog:
-added corrected black level for most shots. Bl corrected for 1/30 shutter so you will have slight tint on slow shutter at extreme low light conditions.
-modified xlib2 to remove tint, and noise
-new menu and icons
Bugs:
-sometimes hdr+ enhanced at 40 frames or 36 frames will not save the first shot, but shot afterwards will save. Tried to find a fix but cannot so use lower frames for most stability, ie.. 25 or so.
Feb 7th, 2019
Update: https://drive.google.com/open?id=1IKGyubiBrdqWVp_gQfmTLaA8HErtoyk7
-added lens blur mode courtesy of san1tyy to take picture of objects and animals
Recommended settings:
-Rear camera set to Pixel 3 XL
-Processing set to 2018 zslr hdr+
-set frames to 40 for min and max for best low light shot (will take some time to process), or set to 20 for both for quick shots
-hdr+ enhance and night sight set min iso compensation to 1/3 or 1/4 s for best shot, but hands have to be still as possible
-exposure compensation to +0.6
-chose Xlib for lib choice
So several have stated that shutter isn't working on global rom, and some other Mix flagship such as Mix 2/2S doesn't work so with help from san1tyy, metadata was cleaned up and should be working now
https://drive.google.com/open?id=1hu9tm0ZSMI3F645rSr2wXq3HhMRP5DUp
Feb 4th, 2019
After bunch of trials and error, lib modding here and there, finally got a working stable version with some new changes with help from Zoran, Savitar, Xtreme, and San1tyy . Lib modding for awb using different calibrations from various devices would not play nice due to either unsaturated or nuclear saturation, especially from S9 series, so I just left it stock for now. Here's the new apk: https://drive.google.com/open?id=1scOaLD8_eeZEdlaR6q1lCXzUSLtb6miB
Changes:
-added compensation exposure
-new lib (Xlib) with sharpened decreased
-frames changed to 40 instead of 45 due to exif cache size error and won't save image
-qc color awb works finally without the yellow tint, thanks big time to Savitar
-UI changes
enjoy guys and donation are welcome so I can get more devices to work on. Paypal: [email protected]
The iso slider had an issue, and wouldn't capture. Also sabre and pixel 3 awb was not included so this version is updated to include it
https://drive.google.com/open?id=11ORyhdqIjFXNlZFsdfA0NDEW8auU3aNr
So sliders had some issue of not triggering for both iso and focus. After multiple test trials, san1tyy and defcomg pulled through again and got it working! APK is also cleaned up to only include Edzman v3, savitar v2, and stock google libs. Enjoy guys.

Make sure you are on the latest global beta from Xiaomi, or the latest beta from xiaomi.eu for camera not to lag in viewfinder and processing HDR+. This mod is based on BSG's latest version with working telephoto lens. Thanks to the great defcomg, xtreme and san1tyy over at telegram, here are the changes:
-added 45 frames, and 50 frames. The 50 frames will cause viewfinder to flicker like crazy but it does works.
-removed ISO limit of 9600 because stock camera can go up to 19000+ iso
-long exposure added for up to 32 seconds in hdr+ enhanced and night sight
-manual focus sliders and exposure sliders
Slo motion should work, motion photo do not work because of lib issue from xiaomi. For configs, use Pixel XL for rear camera, processing use 2018 zlsr+, front camera can use Pixel 3 XL. Using Pixel XL gives correct awb vs Pixel 3 XL which gives a true to life color at night time with low lighting (ie.. 5 to 10 lux).

use xiaomi.eu rom or beta chinese
I am on the official global rom 10.0.11.0
I'm on official global ROM as well and the view finder is incredibly laggy
global rom will do this, you need to be on global beta or xiaomi.eu rom or chinese beta rom
Any news on the global stable update?
I find the Xiaomi forums a pain to navigate otherwise would check myself heh.
Hi xterminater07, Thanks for your work! Its impressive! I use this version of gcam for my LG G6 and works great but I have some doubts about the 32s long exposure. Could you tell me what file inside the gcam package can I modify to try other configurations? I decompile the apk but I cant find where the parameters are for the amount of seconds depending on the lux. Thanks!!!
PD: Sorry for my bad english
All the lags and slowness disappeared after the latest global update (received the ota and updated an hour ago), now when I tried night Sight, taking multiple shots in a row etc etc there are no lags whatsoever anymore for me!
I was just about to flash the EU rom to fix the lags but no need anymore!

Does any one find that you have to tap twice on the camera button to take a pic? Very annoying
Thanks for this great port! Is it possible to implement the option that the portrait photos wont be saved in a separate folder? In the port for Pocophone it is...
Thank you again!
How do I enable the telephoto lens?
Sorry, just figured it out. Enable Aux camera in BSG settings, then double tap change camera icon (the one to change to front camera). It changes from back normal > front > back telephoto.

Does portrait mode work on your Mix 3? When i select portrait it zooms-in and only makes one photo while it says 'burst images'. When i disable zoom on portrait the only thing that seems to change is the zoom, but no acutal portrait shot. Well.. it seems the same as a normal photo

I noticed that it does not work for small objects, but works well with people. I guess the subject has to be far enough for portrait mode to actually work.
Regarding the telephoto lens, there seems to be no noise reduction applied to it, unlike the main lens. This results in very grainy photos especially during the night. Can you add noise reduction, or an option for it for both lenses in the settings? Thanks

Works fine for me, but only for actual portrait photography. It can't recognise objects.

have you tried clicking on the resulting image, if you open it, you will see a blurred one and the non-blurred editions.
so the resulting image is like a folder that when you open, it will have the blurred edition inside it.
Ive discovered that the newest Gcam port from the Pocophone thread also works on our Mix 3! It has more options like save in camera folder when taking portrait shots and so on... Everything works, is there any downside using it?

Does anyone feels LG G8x front camera is so smooth on face selfie capture?

It not sharp and little hit blurry if zoomed in there are no details.
Anyone else?
Yes, today got the phone from flipkart and I felt the same. In some old youtube reviews, the photos looked much more sharper.

Ok that means atleast my phone is not faulty.
I tried gcam as well but no improvement.
Are you from India and if you ordered the product via flipkart during big billion day sale? I found similar complaints from three other users in twitter. But for some, they do not have the problem. May be a defective piece?

The exact issue is that front camera is out of focus/always focusing at infinity. It is not getting focused on the human nearby.
Absolutely same
Yes happened to me too, last morning i received and used stock camera and gcam 7.0 too the front camera photos are so blurry if we zoom in.
Poor sharpness, compared it with POCO F1 and noticed LG G8X thinQ is having very dull front camera sharpness
And poor white balance in nights.
Same in night mode in gcam too.
Please suggest some settings to fix this.
As per Lg we are supposed to keep the camera 30cm away to focus.
https://qhelp.lge.com/share.ncd?mode=F&oid=5094M04UN8&sid=6EL
I think all the phones have this issue as its set on infinity focus.
Happened with me too
The so called 32 Mp Front Camera is so poor. No sharpness, no details and poor AWB.
Even Pocof1 did amazing job compared to Lg G8x.
Tried several Gcams but result remain the same
Yes front camera is very poor..no sharpness..even my 4.5 year old redmi note 3 with gcan takes better selfie
Yep, gcam makes little bit improvement in sharpness but that's it.
My oneplus has way better front camera than g8x.
As well I found that wide camera is also not clear, compared to main camera.
And video from wide camera is very bad.
I have read several tech review blogs that the front camera is fixed at infinity, and hence the face is not focused correctly. It's not a defect, and it's not a recent issue. Even Samsung Galaxy Note 8 has the same problem. You have to keep the device as far as away as possible while taking a selfie.

You are right.
I agree that the stock cam is far-focused that results in very (defocused) smooth selfies. Alternate solution that I tried is to install this Gcam version with a xml config file that I created after playing around with the config of it for quite a while. This should raise the quality of selfies quite a bit and feel free to even tweak the settings further to cater to your preference.
Let me know if it helped and how the results are looking after using this.
PS: After installing this Gcam and downloading the XML file, open the Gcam, navigate to the section "More" from the bottom tiles on the main screen. Between the options that appear on the screen and the bottom tile (from where you selected the option "More"), there will be some space/gap. Double-tap in that gap and an option to select the config file will appear. Select the downloaded XML file and hit OK, the GCam app will restart with the config from that file pre-loaded. Happy Clicking.

How To Guide I am fed up of this ****ty camera processing of Nord 2.

The stock camera app of Nord 2 is ****. It over processes the images and the photos don't look like they are taken from a 50MP camera.
Any suggestions on what to do or some good GCam you can suggest?
Some examples? High mp sensors suffer in low light and have a more shallow depth of field especially up close to subjects. An accurate AF lock is important because of the narrow DOF; example, always try to get a AF lock on the subject's closest eye when shooting a face.
Adjust your shooting style according to the camera's strengths and weaknesses. See as the camera sees not as your eyes see. Human vision has exponentially more processing power and an incredible imaging system more so than any camera.
I want a proper gcam version if available or any better alternative that stock.
Always disable HDR option and pictures will look a lot better (sadly the app doesn't remember this setting so you have to turn it off each time) . The HDR process in the Nord 2 is absolutely awful .
Download the first file in this link. Photos taken with the primary camera will be much better, though I don't think Night Sight works. https://www.celsoazevedo.com/files/android/google-camera/dev-wichaya/f/dl5/
DISABLE HDR. It's a known issue.
But you can't disable HDR when taking photos directly in other apps (whatsapp, telegram, etc)? I had OP8T and it had same issue and I had returned it...
GCam won't give you 50MP. AFAIK the only way to get 50MP on stock Nord 2 is by using the Extra HD feature in the stock camera app.
I'm curious to know if people with rooted devices have this capability enabled in the API. Let us know please

I don't think HDR and other processing options are enabled for 3rd party apps (same goes for the ultrawide lens, you can't use it in other apps) for me whatsapp and telegram pictures look good (but they are heavily compressed)

50Mpx is available in some GCAm versions (Wichaya and Nikita if I remember correctly, BSG and Greatness don't have the full resolution option) , but the 50mpx full resolution of the sensor is totally useless (not only with the nord 2 , but generaly with all other phones) , 12mpx pixel bining gives you better image processing, less noise , etc... a quick look at the reviews explain very clearly why is not a good idea to use the full resolution (50, 108mpx etc...) of a phone sensor.
Personally I use the BSG 8.4 v10 version and pictures are great, Google HDR+ implementation give a lot better results than stock app

Was this on stock or rooted? Btw for me the 4:1 binning is not something desirable since I stack very low light photos, run my own denoising and various other process. Hence why I need the full sensor data made available to apps like OpenCamera

Yes, IM apps do compress photos but that's different story than colour fidelity. In my time with 8T the colours in photo app and telegram/whatsapp were simply blown out of proportion: something normal-red in real life was glowing like burning Mars in 8T photos. After disabling HDR in camera app the photos looked ok (though still overprocessed hence IMHO OP3 photos looked better!) but in whatsapp/telegram I still had same issue with stupid extreme colours...
