Camera: can't get temperature right - Xiaomi Mi A3 Questions & Answers

First, let me say I'm a camera dummy. This is the first phone I have that I try to take pics with. That said, I can't seem to get indoor shots right with this camera. Pics always too bright and too cool.
My room is well lit with florescent warm lights. But pics come out looking like I'm in a hospital room. Bright, cool. I'm in a hotel lounge right now. Plenty of light, not dim, but warm. Pics come out too bright, too cool.
I've tried using all the temp settings in the stock app. I've tried gcam 6, 7, hypercam. HDR off, on, enhanced. AI, no AI. Doesn't matter.
For reference, with a borrowed iPhone 10, default settings, point and shoot, pics come out looking like what my eyes see in same room. Okay, that's a much more expensive phone, obviously, but seeing posted pics I know this phone can take good pictures.
I'd appreciate any pointers. Thanks in advance

Stock camera HDR definitely produces "colder" pics comparing to gcam. Among gcam modes I've tried the most liked was Parrot's Astrophoto V12. Also I don't like elevated ISO of pics produced with stock camera HDR. Can you try Parrot's gcam with AWB mode set to IMX586 in Photo Advanced Settings?

I downloaded the gcam from the link and made setting change as suggested. Unfortunately it did not make a big difference from the stock camera temp-wise. To make sure it's the camera and not the screen, I looked at the same photos on my OLED TV set to warm 2 (closest to D65), it's still skews blue.
Manually reducing exposure helps with brightness, but not so much the temp. HDR is kind of a mixed bag.
Maybe I just have wrong expectations of what a camera should be able to do lol

From my experience stock camera gets exposure and white balance pretty good (AI turned on), very close to what I see with a naked eye. Pretty much all Gcam apps take very cool and desaturated pictures on default settings. It needs quite a lot of tinkering to get them right, and even then stock camera produces more natural results. Stock HDR is a joke (at least in situations where I tried it). Gcam clearly wins in very low light, otherwise I use stock app exclusively.
I would advise to try manual WB settings in stock camera, but you already did that with no improvement (which sounds a bit strange to be honest), so not sure what else to suggest.
About the exposure - what Auto Exposure settings do you have? Mine is center weighted and works good. If there is a face in the photo, it gets priority and the rest of the photo might be under/overexposed, but that's the point of this feature.

How do I do manual WB in the stock cam? AE is center weighted (it's the default). Thanks

You need to switch to pro mode.
Btw.manual white balance works only in certain gcam versions, more often than not it doesn't do anything. The most easy way is to try some "crazy" WB and tap to focus. If the screen doesn't change the color tint, you need to use different gcam version (or maybe change some low level gcam settings, but not sure which ones).
Edit: in Hypercam, enabling "focus tracking" breaks manual white balance settings. Without this feature white balance can be changed.

X10 Camera questions/problems.

Hi,
I'v noticed some potential problems with my camera, and I have a few other questions too to help make me get the best out of the camera. This is all using 2.1 ROM and SE camera app.
1.When my camera autofocuses, sometimes it emits a light 'clicking' noise from the inside. I'm not sure if this is only me, and I want to make sure it's not an oddity.
And about the autofocus, it's terrible sometimes. The autofocus bracket turns red quite a lot, meaning it's not got a lock on focus and sometimes it shoots with the red bracket meaning it's not focused (this happens on touch to shoot mode). Sometimes, it says its focused on something when it isn't. This usually happens when close up, like 15-20 cm away from the object.
2.Image stabilization- is it good or bad? I've noticed camera shots are a bit more grainy with image stabilization on and it takes a bit of time to process the shots too. Does image stabilization make any noticable impact on quality of photos?
3. Metering:Center, spot vs average. Which is the best?
4.How exactly does Macro mode work? I've not seen any noticable difference of pictures using it and normal mode.
5.Is there a way to remove the jpeg compression, or at least reduce it? I think photos could be MUCH better if sony hadn't implemented that.
So those are my questions. Thanks for any help on shedding light to the issue(s)
1. I noticed that click on K750 also, and I think that autofocusing mechanism. And yeah x10 has terrible autofocus, especcialy on macros
2. Image stabilisation is used mostly in night/low light images and it compesates hands shaking when holding camera. It does not do wonders, but it is much easier to take night photo with stabilisation on. Also when its on, pictures are not sharp as they are without stabiliastion.
3. generaly:
average - for landscapes and well lit shots
centre - portaits
spot - macros
4. you cannont autofocus on macro distance(10cm or so) if macro or auto mode isnt turned on
5. only way to reduce JPEG compression is to use vignette aplication with super fine quality (check Camera 360 app also)
one major tip, play with EV always and youll get much better results
cheers mate

28spawn's modded stock camera for 2.1 has somewhat less compressed jpegs and some other improvements. It's in the Themes & Apps section.
I have had a couple of autofocus camera phones now and they have all done the clicking noise during the focusing, so I am guessing that is completely normal. Image stabilization does make the pictures turn out a lot worse, try to avoid using that. And as hibiskus said, the EV controls make a world of difference! Check out this link http://www.digital-photo-secrets.com...xposure-value/ It has some useful information on the EV controls.

[Q] Lock Exposure, Shutter and ISO?

Since the SGSII has a pretty good camera I was wondering if it is possible to manually lock exposure, shutter and ISO settings?
With a full HD resolution I would like to get some nice filming done but without the camera automatically adjusting settings. It ruins the look.
Maybe there is already software out there which I havent found?
Cheers!

The main thing is seems that you'll want to do is to manually adjust the white balance rather than keeping that on Auto.
Exposure lock: There's no exposure lock. However, you can manually adjust the exposure value. So if you want to shoot something bright, you can lower it. If you want to shoot something dark, you can increase it.
Shutter speed. There's no way to manually adjust the shutter speed. (So you can't capture something like a waterfall with slow shutter speed to get the motion effect.) Like most non-DSLR cams, the shutter speed is automatically adjusted depending on lighting conditions, flash, and ISO.
ISO. Yes, ISO can be manually adjusted.
The cam is great and can probably replace most people's dedicated point&shoot cams. But it's definitely not as versatile as even a budget DSLR cam.
The camera changes exposure wile you are shooting. That my problem is.
When I walk out of my flat with my camera switched on I don't want to see the automatic exposure correction. Dunno how to describe but have you never seen the effect when you pan from a window to your wall? It must be possible to lock these settings to eliminate the automatic correction.
What I like to see as an option is the autofocus, I got lot's of refocussing in low light conditions when focus was actually perfect
Also would be really awesome if you could set the exposure time to image starry nights, I mean, the device is called Galaxy is it not
Unfortuanely I am not a developer so I cannot contribute to these options and can only hope some cool devguy with the knowhow has the same wishes as me

Gcam MOD G7 working on V40 (not everything)

Hey guys, last update of GCam for G7thinq working on out device! (not everything is working obviously).
Working:
- main camera with HDR
- wide angle
- portrait
- video at 1080p
- H265 video recording
- night sight (but lags)
Edit: apk with working wide angle (thanks to @Whoareyou)
https://drive.google.com/file/d/1kQq...w?usp=drivesdk
Enable Add AUX
Now switching between front and back camera twice is your switch to wide angle and back!
https://forum.xda-developers.com/lg-g7-thinq/themes/app-google-camera-gcam-lg-g7-thinq-t3855081
Cheers!
Here is an example of stock (top) vs Gcam (bottom). Gcam preserves more details (check bricks for example), and makes low light images a bit more clean overall.
https://drive.google.com/file/d/14j-1hnBAVNeIdqufDQP8F3UeH4swnZ7x/view?usp=sharing
The v40 has a very similar night mode, it just doesn't do much and conflicts with the flash. They seem to have tried but quit
I have an apk I found with working Wide angle but I am not sure which one it is (I've got a few in my downloads ?) I'll upload it here when I figure out which it is.
Edit: https://drive.google.com/file/d/1kQqhAxvcDEQZN8MGu1Qg3WgtuiI7Cyex/view?usp=drivesdk
Enable Add AUX
Switch to wide angle:
Switch to ffc
Switch back to rear
It should now be using wide angle.
@Whoareyou great find man! Works well!
For unfamiliar folks, what makes Google Camera great is the software post processing, particularly Google's HDR, which I never turn off, and portrait - great results. Also somehow GCam manages to preserve more details compared to LG's camera. Now we have working wide angle, I can switch to GCam completely, at least for photos. Night sight working as well, we just have to deal with lag in viewfinder.

Thanks for the link, but am I missing something as far as fixing the extreme lag with the view finder and image capture? Between hitting the capture button and the actual image being taken is several seconds, and the viewfinder lag makes it very hard to use.
I have lag only in night sight mode.
Shutter button works only on second touch for me. And yes, GCam takes a moment to take a picture compared to stock camera, that's just how it works on on phone.

The viewfinder is laggy no matter what for me, and it takes much longer than a moment for the shutter button to register for me. Oh well, maybe I'll have better luck with some future modded APK. The camera that comes stock with the V40 is already pretty good, but having night sight and Google's HDR would be the cherry on top.

P30 pro features/issues people don't talk about much

Hi there,
I wanted to start a discussion about stuff that we like/dislike about this phone, but not the obvious stuff - rather things that are not much talked about. When I read about this phone, most popular topics are about fingerprint sensor, screen resolution, 50x zoom, night mode...
So first, things I don't like:
1. Aspect ratio issues:
- No 16:9 photos aspect ratio.
- Screen 19.5:9 aspect ratio can cause issues in games/applications that only support 16:9 aspect ratio. It's not a huge issue, because most apps support wide screen. It's also the same for other wide screen phones.
- Screen mirroring to TV - because of 19.5:9 aspect ratio, there are black bars on top and bottom, so when you are viewing 4:3 photos on 16:9 TV, the photo is very small and shown only in the center of TV with black bars around it. I don't know how other wide screen phones work, but I guess the same way.
2. Camera:
- There is no way to force the camera app to use the optical 5x zoom in photo mode/videos when the light is low. For me it was a huge issue when I was recording a concert and the camera was jumping constantly between 5x optical and digital zooms. Digital had more view on scene where the light was good, so it jumped to optical lens, optical view is out of sync so bigger part of view was on the dark crowd and it jumped back to optical again. There was no way to record it with zoom.
- How different lenses view is synced - widescreen and normal 1x are in sync when changing between them, you get basically the picture in the same position, but 5x optical and normal are just so much out of sync, that it is very very visible how it switches when you go from 4.9x to 5x. Not a huge issue, but it could be better.
- There is no level indicator in other modes than pro.
3. Speaker:
- The quality is OK at most, when compared to Samsung for example (Samsung S10 has amazing speakers), but it's a phone after all, so I don't expect much anyway.
Now things I like:
1. Huawei Share. My god, this thing is amazing. You can just connect your PC to your phone with WiFi and browse files normally as if it was connected with a usb cable! That is truly amazing. I didn't have it in Xiaomi, newest Samsung phones also don't have it. Why nobody talks about this amazing feature?
2. Camera app:
- Amazing zoom possibilities, 5x zoom which I'm using constantly during my trips and I don't know how people can say they don't use it much. There is something called perspective and this photo shows what I'm talking about. You can get especially amazing pictures when you have mountains in the background. So much discussed 50x zoom is not really usable, but 20x still has amazing quality.
- All different modes, especially the light painting/silky water is nice. Also the pro mode with so many different settings and 30 seconds shutter time. There are much more modes and possibilities than most youtube reviewers show us. They usually just show night mode, 5x zoom, 50x zoom and that's it. Like that's just 10% of options in that app! When you really start knowing the app, it is just much better than Samsung or Xiaomi camera apps. You can shoot much better pictures when you know what you are doing.
3. EMUI:
- I really like this system, the icons, design, features, it's really nice. I don't know how anyone can 'hate' this system? I came to EMUI from Xiaomi and Samsung phones and for me it's just better.
Huawei P30 Pro is my first Huawei phone and I must say I'm really impressed by the price/quality ratio. What are your thoughts?
Point 2: tray to rec videos with opencam or edgecam. You can choose 1x camera and zoom in or you can choose 5x camera. No changes between they.
"2. Camera:
- There is no way to force the camera app to use the optical 5x zoom in photo mode/videos when the light is low. For me it was a huge issue when I was recording a concert and the camera was jumping constantly between 5x optical and digital zooms.

There was no way to record it with zoom."
this to me is a huge issue...as i was trying to photo one of our dogs in evening time and it would only zoom via digital.....every now and then it would flicker to ultra clear optical but not for long enough to get a shot.
no workaround at all for it ?...i see no mention of it in google searches.
i can imagine being in the same situation as you recording a gig and that would be troublesome.

Open Camera allows you to cycle through the lenses.
ID 0 is normal mode with multi-lenses
ID 1 is front camera
ID 2 is main lens
ID 3 is wide angle lens
ID 4 is zoom

You just tap the icon to switch to the selfie camera and when you tap it again it takes you to the next lens. I discovered it by accident

Yes, for photo it works, but then you get no AI... Also normal photo AI handles the 5x zoom when light is low better than pro, I guess it takes digital zoom which is bright and merges it with optical which is dark
As for the video, I tried the open camera, but from what I can see, it only allows to switch between normal 1x and 5x zoom, but when you zoom to 5x it works the same as huawei built in cam app... So it switches to digital and back to optical all the time.
Edgecam also allows you to use all the lenses
---------- Post added at 05:08 PM ---------- Previous post was at 05:05 PM ----------
With edgecam or opencam you can choose the lense.
If you choose 1x lense an make zoom is only digital zoom.
For 5x optical zoom you must change to 5x lense.

Mine stays on optical all the time in video.
Yes pictures are generally better with AI but OC enables you to stay with optical even when light is low.
Issue :ghost notifications.
By ghost notifications i mean there is a sound and vibration but nothing else. Now I am pretty used to them, but from day one and after a couple of updates, they are still present. I have disable notifications from almost all apps except messaging ones, but ghost notifications keep going! Even during night with flight mode on. ?

Actually you can turn it off.
Go to Settings ---> Sounds (or Tones) then pick the last entry and deactivate Lockscreen sound.
I don't know how it looks in english, as my native language is German

[GUIDE] A hint to get maximum detail from the camera

Some reviews as on Notebookcheck.net noted that the P30 Pro camera has a problem with fine details. It can't be noticed on the phone's screen but viewed at 100% magnification on a larger monitor I initially discovered the same.
Investigating the issue further I discovered that when in the default "Photo" mode you touch to focus or use other modes the camera triggers a heavier noise reduction and rough sharpening but when in default "Photo" mode you just let the phone focus without touch focusing it delivers much better fine details. Again this difference is hardly visible on the mobile but magnifying to 100% on a computer or TV screen the quality is very much better.
I am using the 11.0.0.146 FW and camera version 11.0.1.135 but I guess this behavior is valid for other versions too.

There is some issue with the algorithm for sure and while hopefully they may fix this it is good to know and account for. Switching and shooting between modes, e.g. photo-night-photo seems to trigger this difference too.
It is a shame that there is no root since the camera settings for each mode's sharpening, noise reduction, jpg quality/size, etc. are all in text format files and could easily be changed to get much better quality out of the very capable hardware.
