Camera colour sensitivity - Huawei P30 Pro Questions & Answers

I bought the P30 Pro so I could conveniently document oil paintings for my work, though I've noticed that the camera can't recognize lighter hues If there is a colour of the same value with more saturation in the image. This turns the lighter hue grey instead of green, and etc.
I've tried adjustments using the pro camera setting and trying different exposures, but that only forces the image to lean towards a cooler/warmer grey without registering the colour any better.
Has anyone else noticed this, and is there a way I can correct it?

Shoot in raw and edit later with adobe lightroom.

blueish camera?

does anybody having a problem like mine? my camera colors now is bluish! it looks like it got inverted color.. when i shot at people, they will look like smurf!
go to the options and turn off the effects
There is a blue film on the back camera. You can remove that. It's just extra security for the lens. But this blue is a effect.
lol. that looks photoshopped
suggestion
have you thought about making your own blue movies? good money in that sort of thing
thats not it guys..
when my cam is in that error state (sometimes it works fine), i cant even change the effect.. at the first time I thought it got negative film effect, but when i open the setting it shows NONE, and i tried changing it to GREYSCALE, SEPHIA and others, but it wont work..
after several softreset, sometimes it will work fine.. but sometime it just give that bluish tone
I took some pictures outside with grey clouds, white builting, full 3 MP and superfine settings, and automatic white balance.
On my PC they turn out slightly bluish. So the built in white balance is no good.
Can anyone recommend good and simple to use software that can easily correct white balance, for instance by clicking on something in the picture that's supposed to be white?
Thanks

Note 9 yellow photos in low light.

Hey,
I'm rocking a tmobile 128gb blue note 9 and it takes takes some nice photos but I as I was playing around in my house after sunset(night) I took a photo of my couch. I have my ceiling light on, and low and behold there was a HUGE yellow tint to the photos. Not like a filter but more like the default white balance and tone were completely off. Used my moms iphone 7, and the photo was more natural in color from the same angle and lighting. Also swapped cameras and tried my note's front camera and the lighting was also normal. When I use the camera in natural light, the colors are fine and pictures beautiful.
https://forums.androidcentral.com/samsung-galaxy-note-4/457879-photos-yellow-help.html
Googled it and found similar issues, tho thats a note 4.... Any ideas how I could fix this? The photo still has a ton of detail..it just seems again the default white balance and tone is way way off resulting in an inaccurate color scheme. I can post photos tonight when the sun goes down if it helps clarify
Thanks for reading guys !
EDIT: uploaded the reference images from a later post to the main post. 1st image is the yellow hue one from the back, the front camera is the second image and you can see the image is..normal.
I'd be interested to see an example, are you sure the White balance isn't just incorrect?

Here are two photos using an apple as reference...notice the one w/ the back camera is much more yellow in hue than the front camera. I wish the back camera was similar in color to the front colors.
Found this article:
https://www.androidauthority.com/samsung-galaxy-note-9-camera-review-900461/
It seems the note 9 actually may be crappy at determing the right white balance/temp with poor light which leads me to think, if this is the case then why does the back struggle while the front is able to do it properly?

I agree, lower lightphotos get pretty yellowish. Seems easily fixable with a patch. I hope it is.

Thank you for the reply.
I googled a review and it seems to be the case with low light, easily fixable with any photo editing software. You want 2500k for indoor photos, which is what I adjusted the white balance to and then wham, perfect.
The front camera doesnt have this issue, but the back does? What gives? It's obviously a software issue...
I was worried I had a defective unit, but it's safe to say it may just be samsung's software?
Yeah after reading your comment, I used Snapseed and TOOLS - White Balance - AW (auto) on my 3 previously posted photos. Before/after comparison:
EDIT: sorry Ⅰ messed up, some of them came as thumbnails and the newer ones as full size images. To compare it is better if you click-open them all on different tabs and switch between the tabs.

Can only see the before photos, maybe use imgur instead or upload to the forum instead?
Yeah well, if my unit isnt defective and this is widespread perhaps maybe we can get a few more people to test it and submit it to samsung?
Maybe nothing happens but hey worth a shot....it really does seem like an easy fix(hopefully)

Fixed. Now that I fixed it btw, I guess Using Snapseed Auto White did not really give the best results. Only improved the lighting a little. I should try the 2500K thing properly..
BTW what app do you use? All apps I tried until now do not let me specify 2500K, but instead, have a + / - % adjustment slider.
Low light performance is bad beside my old p20 pro

Low light performance is actually pretty impressive.
Here's DXO's Note 9 Low light test vs P20 Pro Low light test.
Note 9 takes the win imo.

I took my photo originally in pro mode, with 'save jpeg and raw photos' enabled. I used all auto in pro anyways, so it's the same as auto just also saves in raw...
I then edited my photo in snapseed, which then prompts snapseed to open its raw editor. You aren't given as much to work with as with a jpeg.. but you can adjust the basic settings such as temp, wb, etc.
Anyways, when you're in 'raw mode' in snapseed, it shows you the default temperature(i guess JPEG doesnt save that info?) and you can slide it down to whatever temperature and eyeball it to see what looks good. Every one of my photos taken indoors with a yellowlish light, if i simply edit it...it becomes normal.
Here's a chart actually for WB: https://www.shopmoment.com/momentist/how-to-shoot-manual-white-balance
Now the question is, why is it that indoors my front camera produces auto photos with perfect white balance but when I use my rear camera, it has a messed up white balance when taken in a room with yellowish lights? You obviously have the same issue, so I think we can rule out defects. I noticed the yellowlish tint/white balance being off in some example low light photos at night actually where theres yellow light present in some reviews of the camera on various websites. This seems like a system wide thing, and would be great if maybe some others could test it out so we could make some noise?
Nope ....

Nope what? If you're referring to off wb, it only appears to happen when the main light is yellow. Otherwise, the camera works fine. Went outside last night and took a photo, it's very good in low light. Inside with the lights on(mine are yellowish in hue)? Photos come out wrong.
In your case...seems to be no major yellow light source.
My photo, willhemmens photo with the skulls and the photo here( https://forums.androidcentral.com/s...21378-yellow-hue-photos-help.html#post6389992 ) with the yellow hue. For some reasons, photos under yellow light are producing off balance hues. Any other light? works perfectly....
Least my case, but maybe I have a defect? It's what im trying to figure out, but it seems like others are experiencing the same. Don't wanna go in for a warranty claim if I don't have too.

Yes the low light indoors is yellowish sometimes.

What "Screen color" Setting do you use on you V40

I switched from my LG V30 to a V40 about 3 day's ago.
I like the things they improved on the phone like the camera's and the reflectiveness of the screen / min brightness.
The thing that i dont like is the color reproduction i just cant get it right. Web gives the best colors but they are washed out compared to the V30 on Cinema. Moving to Cinema colors are blown out of proportion.
Manual settings have the same issue. Saturation neutral is still to much. One step lower is slightly washed out.
When i think i got red on the right value for pictures compared to the V30 a white screen looks red. If i fix that pictures look to green.
What settings do you guy's use?
Left it on 'Auto'. Never one to over-obsess with minor issues. The display is good enough to do colors on its own.
Sent from my LM-V405 using Tapatalk
Tried different ones Auto has been the best. It's a bit oversaturated but white point is good.
I see Auto setting still gives control over color temperature and RGB colors. You left those default? (neurtal and RGB maxed out?)
The cinema setting looks a bit more natural compared to Auto. (less overstaturation) And if i compare my picture to the real thing in real life the Cinema setting comes closer.
I believe I found better setting for myself to fix oversaturated display.
Expert mode, default color temperature, saturation and sharpness all the way down?
Found some extra information:
https://www.xda-developers.com/lg-v40-thinq-display-review/
Seems LG screwed up the Expert mode an almost all other color profiles. Googles does a better job using the same display.
Most accurate is the Web profile. Expert is not usable because color tempertature is above 7100K in all settings.
After web comes the Photo profile and after that Cinema. But that feels to overstaturated to me. While web lacks a bit of punsh. I guess that the UI was not made for the web mode and it looks understaturated because of that when using the web mode.
But for now i guess i will keep using web mode. I want to be able to see if the pictures that i take have the correct white balance and thats not possible in cinema mode. Faces look way to red. Same goes for photo but its less extreme.
Lets hope LG does a better job with the new android version later this year....
Out of the box the LG V40 ThinQ targets a cool and punchy color profile that is about 25% more saturated than our standard RGB color space. In the Auto and Expert profiles, it is possible to modify the display’s overall color temperature (albeit in a flawed manner) and to modify the relative reds, greens, and/or blues. The handset offers 6 other color profiles, and do provide profiles that accommodate the P3, Adobe RGB, and the sRGB color spaces. However, all three of the reference color profiles have a greenish-white point, and only the Web profile (which targets the sRGB color space) competently matches its target (though as seen in our Pixel 3 display analysis, LGD’s panels are completely capable of having near-perfect color accuracy with more adept calibration). Furthermore, none of the color profiles support Android’s color management, introduced in Android 8.0 Oreo, and even if it did, it wouldn’t mean much since almost no Android apps support it.
-------------------------------------------------------------------------------------------------------------
Starting at the profile with the most important color space to target, the Web profile does an alright job at reproducing the sRGB color space. However, as shown on the color accuracy plots above, the white point has a noticeable color error shifting towards green, which is also observable on the plot chart in the yellow, cyan, and cyan-blue color mixtures. Pure reds are also slightly oversaturated, but not too-noticeably so. Overall, the profile has an average color error ΔE of 1.7 and a maximum color error ΔE of 3.1 at 100% cyan-blue and 25% yellow, which is mostly accurate and acceptable for hobbyist-level sRGB color work in photos and video.
The Cinema profile, however, is not as accurate and contains a lot more colors with higher color differences. Almost all colors, besides the gamut primaries (100% red/blue/green), are oversaturated, and there’s noticeable error all throughout the reds, red-yellows, yellows, and greens. The white point shared with the Web profile is also too green. The profile has an average color difference that is considered just-noticeable (ΔE = 2.3), with a maximum error ΔE of 4.2 all around the red-yellow-green region. I would like to reiterate that this profile is meant for content that targets the P3 color space, and everyday use of it will result in content colors that will appear oversaturated.
The Photo profile is also not too good, beginning with the display’s green emitter not capable of reaching the full chromaticity of the Adobe RGB green primary; however, the 100% green color difference is not noticeable. Below 100% green saturation, however, there is noticeable color error with a high color error ΔE of 5.0 at 25% green. Yellows also show a lot of noticeable errors, a few other just-noticeable color differences are scattered throughout the gamut. The profile has an overall average color error ΔE of 2.1 (which is technically mostly accurate), but the high color errors the profile contains makes it unsuitable for color-critical work in the Adobe RGB color space.

Rare screen effect

Hi, I wanted to ask if you guys, have the same effect on your screen. It happens to me only when I'm in low light situations, and it's like, the dark colors, like, mix together with the color that was before in the place that is now the dark color. Only happens when I move any dark/black content on my phone, fast, or not to very fast, but no slow. The best way to see this effect is on dark mode, and on the status bar. Take a reference the white part of your brightness slider. Then, you moove up and down your statusbar, and if you can see it, you'll see like, the dark part of the brightnes slider, shrinks when it's moving (taking as a mark the thickness of the white part of the brightness slider). At first, I thought that this was like a system effect (animation), but then, I saw it on a photo, the same effect, so I think that my screen is defective. I upload a video in slow motion for a better look, and to understand me. Also, I forget to say, but in the video you won't notice it, but, the part that shrinks on the brightness slider, it color, slightly changes to a blueish color.

haven't watched the video, but i think what you're describing is black smearing, it's an amoled thing becuase when black is onscreen pixels turn off

I don't quite understand what do you mean. But for my mi 9 lite, when the screen is all black and only has a few places of lighted up areas, those pixels seems to last a bit longer after it had brightened up.
Idk if that's just what AMOLED does.
This is normal for OLED screens, i have seen same effect on Samsung Galaxy S3 - S9, Nexus and OnePlus phones. Black = off pixels. When they turn from black to something else, they need to turn on. This causes a delay, which leads to the blurry purple affect. It can be slightly annoying but the colors, saturation and contrast outweight the con's IMO, i dont see myself coming back to IPS.
It also happens to me in the Mi 9 Lite. It seems to be some technology used on the screen.

P30 Pro display's color balance leans too red/pink and desaturated. Calibration?

There are a lot of posts and review mentioning this problem about the camera, photos, and videos, but it's not just the output coming from the lens: it's the entire display.
It's not just that it's pinker than other devices: when you look at photos of humans or things you know were supposed to be yellower, it's noticeable and looks wrong, even without another screen to reference. Humans look especially piggy-pink. Sand looks pink. Wood looks pink.
Yes, it's possible to adjust color balance from the Settings menu, but if I adjust for reds, the whites become off-balanced: too yellow-green.
The color temperature wheel also does nothing for a separate issue: contrast and saturation. In Normal mode, it's too muted. Meanwhile, "Vivid" mode comically oversaturates. Compared to a Pixel 2 XL and Pixel 4 XL (and other screens, mobile and desktop), colors (in Normal) are more muted than expected. Parts of images that should be charteuse or neon are instead just nearly-pastel yellow-green. Darks and blacks are nearly greyish.
Can anything be done to calibrate the screen, via root, apps, or otherwise?
