Rolling shutter problem - OPPO Find X5 Pro Questions & Answers

Rolling shutter problems show as dark lines in your photos. In the problem image, it's photographed with an led bulb, which may be the source of the problem. Image 1 is the Find x2 Pro, image 2 is the Find X5 pro. Spot the difference?
2nd image is not showing for me, but hopefully it's there to see...

It's strobing it.
Try an incandescent or change shutter speed.

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.

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:

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 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.

P20 Pro Zoom Issue After EMUI 9 Update and Artefacts Present When Zooming

After installing the EMUI 9 update when I zoom, especially at 10x, the photos taken are not what they appear on the screen before taking them. Instead, the photo taken is something that is lower down to what I was trying to take a photo of. For example, if I try to take a picture of the B key on my laptop it takes a picture of the space bar.
Furthermore, whilst this hasn't only been occurring after the EMUI 9 update, very small artefacts that stay in the same position are present at high zoom, especially 10x zoom (they are invisible at no zoom and only become slightly visible at 5x zoom), when the camera focuses on an object. They appear like small white dots (visible when you zoom in on something that is black in colour as the white dots become more visible). However, they don't appear when taking the photo due to post-processing smoothing the photo out. They are not present though when taking pictures in the pitch black so surely they are not dead pixels? You can though see it on video at 10x zoom. The lens is clean. Is this normal?
Any help is much appreciated,
Thank you.
I've investigated the problem further regarding the first issue and I believe it must be something to do with the telephoto lens not always functioning, which happened straight after updating to EMUI 9, therefore, only the main sensor takes the picture, hence why the final photo appears further down than the preview photo. Also, if I take a photo and then look at it in the gallery and then go back to the camera, the preview image is shifted and the image quality is worse, which would make sense if the telephoto lens is not working when zooming. However, it does seem to work sometimes.
Can someone else test this as it must be a software issue.
I'm on EMUI 9.0.0.168
Thank you.
Telephoto lens preview and capturing will only works when the phone decide that the light is sufficient enough. Else it will use interpolated image captured from main sensor.
This been discussed in other threads as well

Monochrome combined with depth feature

I'm considering buying the Nokia 9 and I am wondering if the camera can use the depth changing feature (bokeh) when taking monochrome pictures. I really enjoyed the monochrome camera on my old Huawei P10, and adding bokeh on black and white photos would be nice.
I know it's an old post, but for the ones wondering, there is no Depht setting for monochrome picture. Also, the picture is taken with one of the side B/W sensor, but the screen show what the centered sensor see. So in the end the photo is not centered as seen on screen when the photo was taken.
The thing is ... if the Nokia 9 PureView when shooting in black and white, it does so only using hardware, this is its three monochrome lenses (as it was said that Huawei Mate 10 Pro) or on the contrary (as it seems be that it does) uses the 5 lenses, the 3 monochromes and the two RGB and then desatura with software filter the image ...
If the case, it is confirmed that it is the latter, without problem in the depth map, in fact it seems better option to shoot the Pro mode (capture in RAW) and then in the edition from Adobe Lighroom desaturate the image, without being deceived, since "purely" by hardware, it seems "not to carry it out" in the same way that when the camera captures in color, the five lenses are always used together
it uses the 3 monochrome sensors.. I don't know who tells the opposite... the preview before you shot is from center rgb sensor desaturated.. but if you cover the 3 monochrome sensors and shot.. innthe start you ll see the image of preview.. but when fusing complete you'll see only a black picture

P30 Pro camera issue: Purple tint. Samples attached

Hi, i am trying to figure out if there is an issue with my Huawei P30 Pro's camera or is it a product/manufacturing fault. I was wondering if a few of the P30 Pro owners could post the following:
- An image taken per instructions below
- Market the phone is manufactured for
Depending on the outcome I can then take it up with Huawei in case it's a product/manufacturing issue. Thanks
How to take an image to recreate the issue
- Switch to Pro mode on camera
- Place the camera on a surface so that there's no light getting to the lenses
- Make sure you are not on Wide or Zoom modes
- Change the shutter speed to 125 (ISO will automatically be set to 6400)
- Take a photo
- upload it here
I have attached a few sample photos below to showcase the issue.
Mine is total black.
Did exactly what you said.
P30 Pro 256gb Aurora Power
Its normal, on high ISO you get wrong colors if you push the dark parts too much. Any because its compensating for vignetting the corners are pushed more.

Camera colour sensitivity

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.
