[GUIDE] Screen calibration: DCI-P3, sRGB - Huawei P30 Pro Guides, News, & Discussion

The "Normal" display mode of the Huawei P30 Pro is more or less correct in terms of sRGB calibration as reviews already found out, but for those who prefer the "Vivid" mode, want to have a wider color gamut, watch DCI-P3 video content or Adobe RGB photos - reviewers just noted that the "Vivid" display mode is not well calibrated in terms of grayscale but didn't propose a manual calibration setting using the color wheel.
I worked with a colorimeter until I came up with a setting maximally close to the correct 6500k whites and neutral grayscale and thought that it may be useful to other users too, after all there is so much wide gamut photo and video content nowadays.
Here is the manual color wheel setting for the "Vivid" mode resulting in a deltaE of 1.5 on my P30 Pro:

Images of bright objects(TV/Lights) taken in dark look very flashy

I noticed it when I was sitting with a friend watching a match on Projector and we decided to click a pic of it from my cam. And you know what I was so disappointed and later he used his moto defy to take pic and it was perfect. The screen looked so clear that we could read the score as well of a cricket match.
Any suggestions?
Tap the screen on the point where it displays the tv. This will set the focus and exposure for picture.

[APP][P]Screen Filter Reduce brightness

Our Xperia P has WhiteMagic technology, Even if we keep brightness to 0% screen will be still bright,
So i found New app on Playstore called Screen Filter.Which works very well on our xperia P
Features:
Reduce the brightness of your screen, save battery.
Applies a shade that acts as a dimmer to ensure your eyes don't hurt. Far more powerful than Android's built-in brightness setting. Great for low-light gaming, web browsing, and eBook reading.

This app cant save battery
It dont reduce the brightness, but just adding a grey filter on the display
I would recommend ScreenDim or RootDim

I don't seem to find any distortion in the above images. Please explain more.
Yeah I had the same on my 7t (regular). Even hq pictures set as lockscreen background look like LQ oilpaintings (painted with 256 colour palette ).
It can be related to buggy iplementation of dark mode.
IMO it's normal. Like a "feature"
Color degradation "feature" ?

A95X F3 RGB bright video in YT

Dear all,
I tried to find solution for my issue without opening new thread but without success.
Namely, my A95x f3 RGB has an issue with Youtube and Video played. The picture is so bright, so I cannot reduce to normal brightness. When I go out from YT, the picture is regular again. In YT the picture is ok before I start the video. And also, picture is OK in bottom bar of YT during video playing but when bar is removed, the whole video is bright again. What could be the problem? My tv is LG 43H6027V.
I have settings YCbCr444, YCbCr422, YCbCr420 and RGB but some does not give signal, and all does not give a soulution.
Here are some pictures where we can see bright and regular color:

Question Color banding with alternative photo apps

Hi,
I have a problem with third-party apps using any "flat" video mode using Camera2-API (e.g. OpenCamera or Cinema 4K): they all produce ugly color banding in the video. An extreme example can be seen below. Did someone find a solution against this? Also it seems that these applications cannot access the image stabilizer.
Sadly, the Google Camera app is unusable for me because it creates over-sharped and over-saturated images and videos. While I can use RAW for images and get decent images, I didn't find any solution against the over-saturated videos - even reducing the saturation afterwards does not make them look natural. At least, the over-sharpening seems to be reduced in 1080p.
All in all, my old Google Pixel 1 did deliver a much better image and 4K video quality which was often hard to distinguish from DSLR images or videos.
