Photo selfie. Background always unfocused - Huawei P30 Questions & Answers

Today I realized about the bad selfies on a cloudy day. I've not tested in a sunny day yet.
The issue is in the selfie, the background is always a bit unfocused. And I'm not using any TOF option.
I'm in the mountains, and I want mountains focused in a selfie photo. That is impossible.
The worst thing is a selfie with the colleagues, if they are 2 meters behind me, they never are focused.
Quite disappointed.
Any of you is having the same issue?

First disable the AI option, the one on the upper part of the screen, in the middle. Then choose Photo on the lower part of the screen, NOT Portrait. I hope that will help you.

Hi,
I did it, but same result.. would like to know if you are having the same.
Regards

When Portrait mode is activated it is as you describe it. Also you can try manual focusing, just touch over any object behind you.

I will try. But my approach is due to focal distance for the f2.
Thanks

P30 series don't have auto focus on its front camera, only fixed focus, therefore you won't get sharp photos of your background

Hi, Thank you very much. I think that is the key, is a fixed focus.
I will have to use rear camera for the selfies I want to have.

Yes, it was answered from Huawei's president itself during an interview wherein he was also asked why 5g was not implemented on P30 series.

If I understand correctly, focus can't be at same place on the subject and also on the background.
The focus is at some distance, and autofocus feature only configure this distance.

Camera is buggy - Too much Noise ( High ISO - 2000-3000 )

Hello,
So I received my all new HTC U11 3 days back ( in India) officially. HTC u11 has world's best rated camera but I am not quite satisfied with the results.
1.) Rear camera is really struggling to capture the photos in low light. I can clearly see the noise.
2.) Front facing camera has no OIS so pictures are blurry and most of the times I noisy photos.
Find the attachments below :
1.) Front facing camera
2 ) rear facing camera
See the noise and level of quality.
hm.. photo #1 has the plant completely out of focus. photo #2 has the pot in focus. you may wanna make sure that the subject is in focus before snapping.
did you change the camera settings to "Touch autoexposure"? The default mode of the camera is "Center-weighted"

Thank you for replying. Let me make the things clear.
The first photo was taken from the selfie camera where I tried to focus on the plant/pot everywhere but it was not focusing anyhow. No matter what it wasn't focusing.
In low light, I can clearly see the noise in the all corners.
The selfie camera doesn't have auto focus everything is in focus ( as long as it is at least 18 inches away). Play around with the settings for the rear camera. HDR auto, HDR, so far all my photos are excellent focal point and background.

Well, in the camera app, pull down the slider with the = icon, swipe to the right to reveal "Settings" which is on the left, tap on that and "Touch autoexposure" should be the first option.
This option is important if you tend to compose your shots with the subject not in the middle (rule of thirds) so tapping on your subject will adjust the exposure and focus according to your subject.
My low light shots are all at over 3000 ISO which leaves quite a bit of visible noise in the picture.
Not liking the camera in poor lighting just yet. Hopefully they will introduce an ISO limiter, or simply fix this in an upcoming update.
I also have a lot of noise in low light photos (rear camera). Automode just isn´t usable if you want to have nice low light photos. The pictures look like that of phones some years ago. Light sources are also always blown out a lot. I also think that the OIS of the U11 isn´t the best out there. So far I don´t really think that this is the best smartphone camera and I was hoping for a better camera performance. HTC told a german magazine in May that they want to deliver an update for the camera. But I don´t know if they really deliver or if this update was the small update of June (?) of the camera app itself. I did this update and nothing changed.
Camera is phenomenal with stunning low light performance.
Check one of mine in auto

Guys, I've been into photography for over 40yrs. - shooting at ISO 3000 will give you noise onless you're using one of the latest Pro or Prosumer cameras w/advanced sensors- the Nikon D5 / D500 are full frame cropped frame verions ef virtually the same camera in terms of auto focus, pic rendition, & yes, superlative results w/astronomical ISO's - which both support. This is a phone, not a prosumer or petter camera. 3000 ISO is gonna give noise. There are a number of companies that make post processing software specifically to help w/Noise. That nite shot the other fellow took is good work.
The phone is great. The camera is quite good. Deal w/the technical realities & don't expect the cellphone camera to deal w/noise like a Pro DSLR.

That's great, but the ISO fired at only 1262.
Whenever I take a shot in similar lighting, auto mode uses ISO 3152, which means there will be a lot of noise.
Perhaps there are different software versions going around, because my phone has very poor low light performance in auto mode due to it using a far higher ISO than it should.

I'm not expecting such a small sensor to handle ISO well - I'm expecting that the camera won't default to a ridiculously high ISO like 3152 where my previous Samsung S6 was happily snapping along at ~1000 with stellar results.
Yes, everyone knows that this isn't a DSLR. But when they claim to have the best smartphone camera around I expect better results. I also don't know why they use a smaller sensor than before... This phone goes for 749 Euro and the low light results often look like from an old S5 or iPhone 4. The Automode just isn't usable in this scenarios. If they deliver an update they could solve the issues, I guess.
Turn on pro mode and drop ISO..

And here in the first sample you can see what I mean with this weak OIS...
Zico, as someone else said go Pro mode & get lower ISO, & even if this phone's camera sensor is smaller than prev ones, - compared to a Pro(sumer) DSLR, this fone's cam compared to prev one vs.
DSLR is like the choosing pinch hitters who bat .249 & .253- the smaller fone sensor is just a bit less than the prev *slightly* bigger one- then there is the density of pixels & dynamic range that make for a good camera - Y am I still talking abt this?
Pro mode and manually selecting ISO is not a solution to a poorly tuned auto mode - it is a workaround that is barely tolerable.

FAKE dual camera setup on Xiaomi Mi A1? [Not Really]

Greetings my dear Mi A1 brethren! Today I am the bearer of bad news for you guys. From unreleased source codes to headphone hissing. This problem is the final nail in Xiaomi's coffin for me. I will never ever buy another Xiaomi device again.
I have reason to believe that the "dual" camera setup on the Xiaomi is FAKE! Let me show you. Follow these steps:
1) Open up the camera app.
2) Cover ONE of the two camera lenses at the back with your finger.
2) Zoom in to 2x mode (or greater).
Did you notice something? THE CAMERA LENSES DO NOT SWITCH! The main point of the Mi A1's dual camera setup is that one lens is wide angle and the other is telephoto (as mentioned on their website). When you zoom in, the app should automatically switch cameras.
Another test is that the dual camera setup should provide a background blur (bokeh effect) on objects that are up close to the camera. Cover a lens with one of your fingers and you'll see that either the camera gets blocked by the finger or the blur effect still remains (regardless of the fact that TWO cameras are needed for a proper bokeh effect)!
Both these tests prove that one of the Xiaomi Mi A1 cameras is a dummy. Has Xiaomi lied to us again? Why would Google let them do this?
Or is it that I don't understand how dual cameras work? Someone please enlighten me. I feel I've wasted 250$ of my hard earned cash on a scam
EDIT: Nevermind! I just found out it does work. But only in manual mode or portrait mode. Strange that the app does not switch to telephoto mode automatically. Perhaps in a future update.
Have you tried manual mode
MayanKKaushik said:

Yes, I did. I've edited the OP. I feel like a goof for not trying that first
No its real!
Try that in outdoor lighting conditions.
In natural lighting cover the zoom lens, and then hit the 2x zoom.
You will notice that the zoom lens is functional in good lighting conditions, not in bad light conditions.
Same with the portrait mode, thats why it is recommended to use 2x optical zoom and portrait mode in outdoor lighting conditions.
The camera decides if it should use digital zoom or telephoto lens depending on light conditions. Telephoto zoom only works with a lot of light(like portrait). If there is not enough light, digital zoom from wide angle lens is better. This even happens on iphone 7plus/8plus camera set up(if there is not enough light they just use digital zoom). However, I think that maybe it switches to wide angle digital zoom sometimes in good light conditions.
I can understand that you were concerned but please test things thoroughly before posting (or maybe Google it out). Actually the telephoto camera have a narrower aperture then the main camera. So it captures less light then the primary camera. When who cover the telephoto camera to see if it is working or not, then hit x2, it detects that there is low light (since you are covering the lens) & hence uses the primary camera. Okay, so this is how you should have tested. First go to a very will lit environment, then select 2x zoom, and then try covering the telephone camera. You will get the proper results. Hope this helps.
It's the same in Oneplus 5, for example!
Telephoto works properly only in good light situation

If you want to know before clicking a photo which lens is used for 2x zoom just look at the animation when you use the zoom button. If theirs an animation of zooming then it's digital zoom & if it is directly switching to 2x or 1x then it is actually switching between the lenses. And it won't change with a future update too as the OP hopes. Works the same way even on iPhones. It OK to have questions but you went too far calling it a scam, fake & never buying from Xiaomi again.

How to take best picture in very strong light condition with HRD+/HDR+enhance

Hi all
when i take picture of my yard in bright sunlight, when i open the camera app and choose the HDR+on/HDR+enhance with autofocus, the yard in the camera screen is over-exposure, and when i take with HDR+on/HDR+enhance it doesnt change any thing when i saw in the camera screen, it quite strange, because i thought that function should process the over/under-exposure to keep the best detail, highlight and make the picture as real as it can ? what do i miss ?
and one more thing
when i tap the screen to focus to the sky, all around object and bright become darker and when i tap to the yard the bright around is brighter but the sky is lost detail of cloud and the building, it's normal ?
sorry cause i'm newbie with google pixel
Note: i post my isssue to topic https://forum.xda-developers.com/pixel-3-xl/how-to/share-pictures-pixel-3-xl-t3854033/page12, but i think it would be better if i make new seperatelly topic

Normal camera photos look bit more blurred than normal? Bokeh effect?

Hi,
I received my Mi Note 10 and I've been testing the camera. Am I the only one that thinks that while taking normal outside pictures (27mp mode) the image taken has lots of blurriness and distortion? As of now I'm not really enjoying the phone.
Came from a Mi Note 3 which took amazing pictures.

Yes, I'm going through the same thing ... I can't get clear answers on this subject. Only thing I know the camera aperture is too big so taking close-up shots of the blur is terribly bad, I don't know if future updates will fix it. I came from a Mi 9 and his pictures were better than the Mi Note 10
You need to understand the implication applied when camera using a larger sensor. This is not only about apperture and lenses. I explain it in other thread.
But there is nothing we can do, even in Pro mode? We cannot setup the aperture, so the depth of field is quite ridiculous. Can have a clear picture of a bottle label if the camera is not exactly parallel lol

I think he is being fair enough though. Because what you expect is like using a fix apperture lens on a full frame DSLR, and still expecting a result with wide depth of field unconditionally.
It's simply against the principal and law of the photography physics itself.
If you really need that, then you gonna need phone with either : smaller sensor, or less bright lens, or both.
I don't think it is, it's a question of software. I was sitting at a table wanting to take a photo of our cocktails. Mine was in focus, the one right behind already blurred. I understand that physically this is normal, but software should be able to take a photo with everything in focus.

Nah. You can think what you like then. The physics wont change. And every people who understand the theory behind depth of field, will agree.
I know what you expect the software to do though. Sharpen the object in background or do focus stacking. As for sharpening, it' just a pseudo focus, and i rather not having it at all. Focus stacking, though, is considerable,
If thats what you like, then just get yourself a photoshop and do some layer masking job, because no stock smartphone camera app implement focus stacking AFAIK. The closer you can get is by using "Open Camera" app and use the focus bracketing software.
You can 'kind of' fix the effect in software by using focus bracketing. Open Camera supports this and you specify how many photos to take and it will take that number at different focal lengths. Then you process the images with some stacking software like Helicon Focus which produces an image with a huge depth of field.
Of course, this is all more complicated than just pointing and pressing. A nice feature would be if the camera software takes all the photos and stacks them for you, but I doubt any camera software will do all this for you..

Mine had a focusing problem and what I did? I’ve changed to full mode instead of 3:4. Regarding the focusing around the center, I don’t think there is a solution than using more the portrait mode.
I’m not a camera guy so these setting were enough for me.

Question TERRIBLE photo corner softness?

So I got my S22 ultra yesterday and overall I am very satisfied with it except the sharpness of the corners from the main camera, my old oneplus 8 pro is so much better at that.
It is very noticeable when shooting RAW photos or 108mp.
Is there anyone else with this kind of issue or maybe I got a defective unit?
Left is oneplus right is the s22.
It's the lense. If more than other copies, it's a bad copy. This happens.
Some corner blurring is typical and acceptable. Blurring near the center especially and as it you go outward are far less acceptable.
Every lense has a blur chart that varies by degrees throughout it's image. Even the best primes have blur; this is an exception lense that goes for over $5G! It's blur chart is near perfect.

You need to compare the same lense/cam model. Go to a store and try a demo or two.

They might be the same sensor but the S22U has a wider main lens than the S21U. Wide lenses are much more prone to distortion and softer corners. Definitely hoping future models go back to being less wide.

For wide angle use the save option to automatically apply correction. This is for primarily image distortion though.
Interesting. My camera app does not have the ultra wide correction option. The other two options are under "picture format". My old Note 20 did have that option.

That screenshot is from my N10+ running on Pie... meh, I don't like rude surprises
Both photos (on the link on the end) are in 108 mode, 2nd taken seconds after the first, so conditions are the same.
On the 1st photo I have just pressed shutter button and that's it.
On the 2nd button I have taped with finger onto the TV tower on the right to lock focus/exposure and then pressed shutter button.
Results are interesting. As you can see on the 1st photo, trees are detailed and sharp, in focus, while the TV tower is blurry, without details.
But on the 2nd picture, you can see the TV tower (or windows on the buildings) has details, even it is in the corner where sharpness is lower then in the center.
I don't understand this behavior, since there shouldn't be any difference in focus because of the distance from the subjects. In normal 12Mp mode everything is sharp and in focus across the image.
I don't have explanation for this behavior, since the size of the sensor, focal length and distance from the subject shouldn't have any impact on that. It looks something is broken in the image processing pipeline.

Thanks for the samples, I tried to focus on the corners too and some how it got sharper however the center of the image got worse even though everything should be in focus.
In 12mp mode it just boost the sharpness with processing. that's why everything is sharp.

Yes, you can have sharp center or the corners, but not both. But why?
I don't think in 12mp mode it is just boosting the sharpness, if it is out of focus, it can't be fixed by sharpening.
It may help if you submit a bug report directly from the phone via the member app as I did (still waiting for reply from Samsung) - more reports, more attention.

Because of the blur pattern and dof.
All lens have it and you can't have all points in focus at once especially with a fast lense. They always have a shallow depth of field. Even stopped down only objects at the same distance can be perfectly focus and there's always some blur even than.
You can't stop down these smartphone cams, one of their limitations; you're stuck with a wide open lense.
Multi element (typically 7 elements or greater) lens can correct for it to a greater extent but you see the blur chart example I posted. That's one of the best primes available, all $6G's of that beast.
It's not just the blur pattern that the optic engineers need to address. Different colors have different wavelengths so they want to focus at different lengths. There are many tradeoffs. With only a small number of elements in a very small space the options are limited. Price is another consideration.

Multi element (typically 7 elements or greater) lens can correct for it to a greater extent but you see the blur chart example I posted. That's one of the best primes available, all $6G's of that beast.
It's not just the blur pattern that the optic engineers need to address. Different colors have different wavelengths so they want to focus at different lengths. There are many tradeoffs. With only a small number of elements in a very small space the options are limited. Price is another consideration.

But in the standard 12Mpix mode everything far enough is sharp and in focus, using the same lens, only in 108Mpix mode you see this issue. Your statement is valid, but with tiny sensors in smartphones all distant object must be equally in focus. I can't achieve such blur for distant object with Full frame mirrorless (35mm f1.8) and that is another league.

So I got my S22 ultra yesterday and overall I am very satisfied with it except the sharpness of the corners from the main camera, my old oneplus 8 pro is so much better at that.
It is very noticeable when shooting RAW photos or 108mp.
Is there anyone else with this kind of issue or maybe I got a defective unit?
Left is oneplus right is the s22.

The shaky shot in S22 and steady shot in Oneplus, clean the lens and try without shaking the device, or maybe as you said it could be a defective phone!
After a comparison with s21 ultra there was a slight difference in sharpness, however I don't know why but the colors were much better with the s21.
I'll compare them again later.

Because of the blur pattern and dof.

Just like glackey said, even with my FF camera both of the subjects will be in focus, I don't think that DOF is the issue here.

Both of the phones were steady and the lens was clean.
