P20 Pro Zoom Issue After EMUI 9 Update and Artefacts Present When Zooming - Huawei P20 Pro Questions & Answers

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.

Need camera help

i have the kodak easy share C1013 which has 10 mega pixels apparently. but the problem is my phones comes blurry what ever i do, even if the flash is on for some reason, but this only happens indoors and even if the lights are on...if anyone here is good in camera, can they help me pls

see the third photo on this thread i clicked it with the flash on
Well the third photo the picture is recular out of focus. The problem with Point and SHoots is that they take a while to focus (especially in low light) and (this with all cmeras) the shutter speed has to be much lower for the sensor to gather more light...and P&S's have tiny sensors compared to an APS-C, CMOS, ir a full frame sensor. But you should just retake that shot making sure the camera is focused and maybe add some more light on the subject to make it easier for the camera.
Are you using a manual setting? Have you dropped the camera? How close are you shooting?

i alway focus my camera properly, when ever the focus is right, the box thing becomes green. how to lower the shutter speed i will take some photo with plenty of light. also the the the third photo was taken in a room full of light and also with the flash on
You mentioned that the room is well lit. But perhaps you are standing in front of the light and casting a shadow on your subject?
You mentioned that the camera has locked focus before you fully pressed the shutter. But with inadequate lighting, perhaps the camera is focusing on the wrong spot?
Some cameras have a light that comes on when you half-press the shutter to help the camera focus in low-light. If your camera has this, then make sure you enable it.
Also, if you didn't crop the photo, then perhaps you are holding the camera too close to your subject. Try backing off at least 2 or 3 feet. Then crop the photo with an editor to exclude anything you don't want.
You could also check settings for your focus point. It could be set to spot focus off center, I've seen it before.

i tried what you said and see the pics i uploaded, but still i dont find the quality of a 10 megapixel camera tho
For those types of pics you need a camera with a macro feature/setting.
good day.
The 3rd and 6th photos are blurry because your subject spans a large depth of field. In those two photos, the base of the iPhone is close to your camera while the top of the iPhone is far away. The distance between these 2 points is too large for your camera to handle (especially under those lighting conditions). Your camera needs a smaller aperture setting than it can handle for those shots.
(In the 3rd photo, the camera seems to have focused on the farthest point. Notice that the top is in focus but the bottom is blurred. In the 6th photo, it's the opposite. Notice that you can clearly see the cracks in the cardboard box on the bottom while the top is blurred.)
The others look on par with what you should expect from your camera under those lighting conditions.
Remember that more megapixels doesn't mean better quality.
The following is just a tip. Lighting is important. Try to take your pictures with sunlight. Don't depend on your camera flash. If you use your flash aimed directly at your subject to compensate for lack of lighting, your pics will look terrible more often than not. (I see from the reflection off the rear of your iPhone that you're using a lamp as your primary source of light. That's not adequate...)
Shallow depth of field is not a bad thing with good lighting. It allows you to highlight certain aspects of your subject. See the following examples.
1st Pic, 2nd Pic, 3rd Pic
The 2nd pic draws your eyes to the bottom right corner while the 3rd pic draws them towards to the top left.
These were also taken indoors with a 10MP camera. But I used my Nikon D60 with SB-400 speedlight to bounce the flash off the ceiling.

[Camera] Is it just me .....whats your settings?

Ok coming from Samsung , HTC, Asus and iPhone (I know I here you gasp)
I pretty much use my rear camera alot for work purposes, no selfies
Mostly its point and shoot I do and I know the camera on these are for ppl getting the right shot manually due to the settings
Have tried apps on this phone Like :
Camera FV-5 (same kind of results)
Open Camera (which seems to stay active in the background)
Now heres my question if you quickly take a photo, point and shoot (focusing first) using highest resolution
Once you zoom into the taken picture, its all grainy even if its took about 3-4 feet away from you
Now, if you take the same picture with monochrome its a better pic and if focusing on say a bottle with writing
Its more visible to read compared to the colour as the colour looks like its a water painting
Are you guys getting the same results or know preferred settings to use?
Thanks
Try to set the resolution to 12mp to enable the 2x "optical" zoom.
The color sensor is only a 12mp one, the monochrome sensor has 20mp.
If you enable 20mp in settings, the camera will make a monochrome and color photo and merge them into one. This is also the reason why the 20mp photos are a bit blurry or too bright on edges.
So, use 12mp and the grain should be mostly gone.
Here are three shots by me:
https://imgur.com/a/BYf7kIX - played with focus, no aperture feature.
https://imgur.com/a/xA2qURk - just a free hand picture in 12mp without zoom
https://imgur.com/a/RbEdeiI - and the same with 2x optical zoom.

Everything stock, 8.0.0.370 on VTR-L29C432, stock EMUI camera.
Can you show some examples?
Desk is about 4-5 feet away from me when taking these shots
Sunny outside
Just normal photo and putting focus on the bottles as shown (seen in zoomed photo)
You can clearly see they look terrible apart from monochrome
No settings have been touched apart from resolution
Zoom is about 4.6x
Monochrome
12MP
20MP
Zoomed in
I put some crap on the desk but if you can see the text is visible on some stuff to give you an idea

Panorama mode needs some improvement

Perhaps I'm doing it wrong, but I just can't get the panorama mode to work properly with the S10+.
I have 2 major gripes with it:
The panorama doesn't go all the way around, so I don't get a full 360 degree panoramic photo
The photos always come out distorted/stretched when viewed elsewhere
With issue one, it only seems to take about 350 degrees, so I end up with a stitch that doesn't quite work out when I view the photo later. Apps like Google Photos helpfully turn these types of images into something similar to being there and rotating on the spot but because the phone doesn't seem to take a full photo this doesn't work properly.
On issue two, when viewing the photos in Google Photos or even Facebook, they try to make these images into a photosphere type image, so 360 degrees along the X and Y axis. The trouble is, even though these photos are taken with the wide angle camera, it stretches the image upwards and distorts it to get that 360 view. LG wide angle cameras (at least on the G6 which is the last one I owned) add about 10 degrees to the top and the bottom of a pano photo using AI to match the colours at the top and bottom (e.g. extra blue at the top for sky). This results in a blurry patch at the top and bottom of the photosphere, but also prevents the main part of the image being distorted.
Its a shame about both of these "features" as otherwise I'm pretty happy with the camera, but having distorted panoramas is not great.

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

Mi 9 stock camera app question

I have 16:9 mode enabled, but viewfinder (i.e. the screen) has this big semitransparent black area on the right that makes it difficult to visualize what's in the picture. The shutter and some options are on this big black stripe. But it is really getting in the way.
In 4:3 mode the stripe becomes solid and everything is ok, but in 16:9 part of the photo is actually behind that stripe which really makes it hard to take good pics.
Any solution or workaround? Do most people take 16:9 pictures these days?
I try take 16:9 it's look zoom in on camera app but after take photo it's look normal
