Question Photo's corners softness - Samsung Galaxy S22 Ultra

Hello, is the softness/blur normal at the corners or it is a defect?

Optical limits of the lense.
All lens have a blur profile and are not equal across their fov especially in the corners.

I can see some corner blurring in the link shot, normal.
Brace the cam before shooting test shots so there's zero cam shake, use the spen bt as a remote shutter release. The cam's IS may be at play here.
If you look at blur charts for Canon L lens costing thousands of dollars you'll see similar results especially wide angle lens. Blur is a problem when it's not sharp near the center even by a small amount.
You can return it. No guarantee the next one won't have a worse blur profile though.

Vote please

I can't vote because I would not use a shot like that to test for corner softness. Remember the main camera is an f1.8 lens, so it is going to have significant depth of field focus differences. I'm assuming that you used the main camera. In your shot you are focused on something at middle distance, while the right side is close and the left side is pretty much at infinity. I'm just saying that it complicates evaluating your shot for corner softness. You could do a better test by taking a landscape where everything is far enough away that focus distance does not make a difference. Also, Samsung made the s22U main lens a little wider (23 vs. 24mm in the S21U vs. 26mm in the Note 20) so that isn't helping because the wider the lens the softer the corners, generally soft corners are the price for wider angle. Just an opinion.

I saw a 22U where the softness didnt visible at the corners...So I think there are some better quality lens in s22U phones. https://imagizer.imageshack.com/img922/448/7VEHLp.jpg
Strange I cant see the softness here on my Ultra's shot :

A simple image isn't a proper blur test.
All lens have corner blur to some extent and this isn't a high dollar lense by any stretch of the imagination.
Here's how a wide angle high dollar prime lense for a full frame sensor stacks up.
A interactive blur chart for a Canon L lense:

Notice how some corners have less blur. No single or compound lense is perfect. Blur is only one optical considerations of the many optical properties of a lense system

This is normal. You aren't aware of it but there's a subtle blur pattern across the whole image.
Blur is always present to a greater or lesser extent.
All lens have this. There is no perfect optical system.

I noticed something strange.. if the corners are softer the middle of the photos almost perfect. If the corners are fine there are a lot of random blurred area on the shots. I think the corners softness is "better
So I can keep the phone if Im right.

A typical blur pattern.
The way you grade blur is by center sharpness, how far it extends and the evenness of the blur pattern. Unless you're looking for it, it blends right in. If it really bugs you, crop it out.
The worst spot for blur is dead center, hard to work around a soft lense...

I think so honor 8 camera dual tech is fake

I've been honor 8 since one week and i have found one thing that when even i cover right side lens it capture black image but when ever i cover left side sensor it's take snappy sharp image like it's ideally take . So i think so it's just fake second camera is dummy or any other problem ? please let me know i'm worried for my money
Are the pictures good? If so then don't worry about it.
Sent from my SM-T713 using Tapatalk
From my experience the second camera is mostly used for background blur effect. If you cover the lens, everything is in focus.
It is also used for minor noise reduction. If you take a picture in low light and cover the secondary lens there is a little bit more noise. But you won't really notice it unless you enlarge the image.
well the fact that when you block one lens, the other works is proof that neither is dummy. perhaps the post processing is not that dramatic as you were expecting. try taking low light pics with both and just the normal lens then compare them by zooming.
no difference found
I've tried in low light too but second lens is just a fake . it's don't enhances quality i think so i have to wait for android N update

I love the pictures the Honor 8 takes when using the Wide Aperture mode. It seems the second camera is essential for creating the blur effect. If you haven't noticed you can go into the Stock Huawei Gallery and adjust the wide aperture pictures after the fact. Even if you took a picture that looked like you focused in on the wrong thing, just go into the Gallery, click on the wide aperture button (only shows up on wide aperture pictures) and select what you wanted to focus on.
Sure enough, without the second camera the wide aperture mode doesn't work properly if at all.
Second lens is for focusing, depth of field, and additional light. As well, when covering the second lens, it persistently gives a warning about not covering the lens while shooting, especially when refocusing. I think this should be enough to disprove your "fake camera" theory.

Yea the S9+ has almost double the bitrate, and fps. Sound quality does seem a bit better on Note 8.

How did the file sizes compare at the end ?
One's using h265 and the other h264 ?
4k means huge sizes. I recorded an hours worth of 1080p 60fps on my v20 and the total size was 16GB
When the lights go dim, the 9+ walks away from the pack. Party's over, there's simply no comparison!
S9+ not quite walking away with much here is it
The Note 8 looked better to me until it started moving. Then it was much better on the S9+, I think.

That's not low light LOL.
I'm talking sub 1 lux levels. Think a 10x12 room with a night light or clock radio in the corner.
Also, his lens isn't clean *enough*.
If you really want to make sure your lens is optically clean you MUST use a lens pen. There are other ways used by laser techs but aren't even valid outside a class 100 clean room anyhow.
Anyhow, under low light the S9+ most certainly walks away from the Note 8. I have both phones and honestly was surprised at the difference.
The only thing I haven't tested is audio zoom and distortion at high levels. At the next warm up I will certainly zoom into one of the subs and see if it turns into clip city.
Excessive AF hunting seems to be reduced. Now if we could get rid of the AR artifacts and rolling shutter distortion we'd have some serious reasons to leave the pro gear at home. (haha I kid, but hey it's getting closer all the time!)
FYI indoors is low light and that scene is as bright maybe a little more. But the point is in such a situation anything from the S7 on up is fine. With LG's G4 and upwards. That is perspective. Comparison. Not just seeing something alone and imagining how much better it must be which is hype
His lens is clean enough for the purpose. Its called micro fiber, you should try it some time.

I'm not saying it's not fine, I'm saying the S9+ is demonstrably superior to both, enough to warrant purchasing even if you own the 8+ based on the camera alone. And indoor lighting certainly can vary from overly bright or totally dark.
There is no imagining anything here. I own the devices and can clearly see the differences in processing both on stills and video.
Additionally, if I can easily see artifacts produced by a FOD covered screen, it's definitely NOT clean enough! Microfiber is nice and soft and won't scratch delicate surfaces/coatings however if it's not clean it's not going to produce a clean surface. A lens pen will. They are cheap and no one that's even a bit serious about photography shouldn't have one!

Which lenspen do you use with your phone ?
https://www.amazon.com/Lenspen-NMCP-1-LensPen-MicroPro/dp/B007G620ZE
or
https://www.amazon.com/LensPen-MBK-1-Camera-Cleaning-Kit/dp/B0010HAAIO
hopefully these aren't knockoffs with pads that come off after a few uses
Never heard of these products in mobile camera space.
How do you tell its clean, eyeball it at an angle like with any lens.
You're saying a lens pen will do better than microfiber. Well, i've ordered the first one since it works out to a quarter of the price of the second on amazon India and has a pad small enough to fit.
Hard to tell what coatings these phone camera lenses have, i'd imagine something that makes them resistant to scratching. Whether a lens pen will be safe to use in that case
Yes there are knockoffs but the lens pen brand, Nikon, etc. are OK.
The smaller pads work best but a 10mm pad still works. Use the brush first to remove loose dust and then use the pad.
I usually swipe across a few times.
You will know when it's "optically clean" when you can point the camera at a bright, pinpoint source of light (streetlight at night, etc.) and there's no halo or line shaped artifacts. The pens are quite gentle as they are designed for cleaning optics with AR coatings which are much more sensitive than the outer glass cover. If you look at the camera lens on a phone at a slight angle you will notice a purple looking color. That's the coating on the lens. Fortunately, this is protected with a window.
And this is why I use a UV filter on my expensive Nikor |N| and Canon L glass because a $30 filter is much cheaper than repairs that can cost $1000 or more!
I think S9+ is designed for better camera compared to Note 8

Camera OIS/sharpness?

Hi folks,
I am presently playing around with my P40 Pro, especially the camera as this is of special interest for me.
I am comparing with a Oneplus 8 Pro.
What I noticed is that the P40 Pro camera is giving a lot more blurred images at medium to lower lighting, in fact it's surprisingly diffcult for me to get a sharp indoor shot.
This is on .122 Firmware and I am bit at a loss on how to tackle this, in fact it's a bit disappointing for such a hyped camera.
Isn't the P40 pro camera supposed to have OIS?
And this is with very comparable aperture and shutter speed between OP8P and P40P...
Am I the only one? Any suggestions?
Thanks,
Axel

Yes... Why?... Is there a known influence?
What do you exactly mean by blurred photos. Motion blur or out of focus blur? Motion blur is caused by slower shutter speed. Focus blur by focus failure. There is also blur(bokeh) caused by much bigger camera sensor used in P40 PRO. So depending what your subject is you may experience different results. Longer shutter speed and lower ISO is preferred for best image quality as long as you have static scene. But in scene with moving object, object in motion can be blurred. Personally I am on .121 and I rarely get blured photo due to any phenomena described above.

To me it seems like motion blur from camera shake... But images at around 1/30s with OIS should normally be fine - at least they are on the other handsets I tried...
This is why I am asking, maybe OIS is not working... Anybody got an idea to test this with some tool?
Have you contacted Huawei customer support? Could be faulty, it also may be worth checking out the huawei community page to see if that is the case

Yeah, firlando code method creates on my night shots some effect lines and on a1234567 method i have good night shots but blurry fotos on daylight... Today i will try to use my phone without Googleplay services...
This installing method on Google services witch you need to go on apps and delete playstore etc i think is the keys for the problem... We need a clean installation without deletations..

Wrong
Observation about the lines in the foto. Lines are reflections from lights. I realised it today. Im testing camera without Google services. Tomorrow i will test on daylight.. I think 121 update is bad update.. is there any way to roal back to 112?
Here its a foto without Google services... Still no sharp almost blur... I think is Just the 121 update is worst than out of the box 112 version
We just w8 the 127 update

I am also disappointed with this update (121) pics quality is average but video quality is lower than on p20 pro.
Zoom doesn't seem to work properly either - it's digital up to 8,5 -10 x then periscope kicks in.

Erm ... I don't see anything wrong with that picture.
You focused on the closed petal at the left side, it's perfectly sharp, rest blurred as it should be. Not the prettiest bokeh, but okay.
Do I overlook something?

Again, I don't see what's wrong with that picture. Maybe you could point out the problem a bit more in detail?
It would also be quite helpful for sorting out culprits if you (and anyone else) accompany your pictures with some EXIF data, like shooting mode, AI on/off, ISO, exposure, aperture and zoom factor. Unfortunately, XDA seems to remove that data from posted pictures.

That's indeed the case with firmware .121. And it's far worse in the "Pro" mode, rendering "Pro" mode almost useless.
Let's hope the next updates home in on that fault.

EXIF data? Answers to me previous questions?
These are important information, e. g. telling me about the aperture of the lens used, making a difference regarding depth of field, possibly explaining why you *perceive* a picture as not okay.
Besides that:
Similar quality, similar sharpness - if not identical.
This time, there was more distance to the subject, widening the depth of field, the "sharpness range."
Let's assume the picture was taken with the main 50 MP camera, having an aperture of f/1.9 - a big difference to the aperture of the telephoto lens with f/3.4.
The smaller the f-number, the larger the physical lens opening. And the larger the physical lens opening, the shallower, smaller the depth of field.
Meaning: With a shallow depth of field, a few millimeters more or less distance to the subject can make the difference between razorsharp and blurry. Result: Only objects exactly within the depth of field are rendered sharp.
With a wide depth of field and a larger distance, like with the telephoto lens, it's less crucial, every part of the flower will be sharp.
I would show you example pictures if I was allowed to use external links - but my post count is still too low.
Just try taking pictures of the same flower with different lenses, one with the 50 MP main camera, one with the telephoto lens. With the latter, increase the distance till the flower roughly occupies the same space in the viewfinder as with the main camera.
Important: Use a zoom factor of 10, not 5 - this makes sure your really switch to the telephoto lens. At present, there's a software bug causing the camera to often use horrible digital zoom for 5 x instead of the real telephoto lens (seems to be connected with the metered subject's distance). You can check this by covering the rectangular telephoto lens with a finger. If the picture vanishes, the lens is doing it's job.
You'll find out that the photo taken with the main camera has sharp and blurry areas, while the photo taken with the telephoto lens is rendered sharp everywhere.
That's the results of aperture and distance.
And that's why I don't see anything wrong with your first flower picture: Wide open aperture, small distance = tiny depth of field = tiny area of sharpness.
The way it should be because we all like that bokeh effect (blurry background, making the subject stand out) more than typical "flat" smartphone pictures.
But this benefit is paid with a drawback, the small depth of field, rendering everything outside that "sweet spot" blurry.
Perfectly normal, nothing to write home about.
Oh wait, I'll dare to post a link anyway - hope the moderators won't kill me for that impertinence.
Just took two quick photos right outside my house, clearly showing the effects I explained above.
http://waagerecht.com/kram/Flower_comparison.jpg
Picture is quite large, so be warned.
Telephoto: ISO 50, f/3.4, 1/196 s. Main lens: ISO 50, f/1.9, 1/846 s. Both shot in Photo auto mode, no AI.
About that numbers: ISO 50 tells me there should be no grain in the picture; the higher the ISO, the more grain in the picture.
f/3.4 tells me there's a wide depth of field, so there should be no greater blur. Also tells me the telephoto lens was used. f/1.9 tells me to expect blur everywhere outside the "sweet spot", main lens used.
1/196 and 1/846 tell me about very short exposure, so in-motion unsharpness (camera shake, moving subject) is very unlikely.
And because the telephoto lens has a smaller aperture of f/3.4 (and lenses with a higher curvature), less light reaches the sensor, thus exposure time is greatly increased, 1/196 s versus 1/846 s.
See why I asked for that data?
You'll see that the telephoto shot is all sharp (until you zoom in; lower sensor resolution plus digital zoom, today's modern pestilence), you can even see the structure of the green leaves, while the main camera shot has everything blurred except the flower's pistils.
That's just the way cameras work.
So enjoy your fine camera, it does a great work and does it right.

Jeasus Christ i never used 50 mp sesnor i use the normal sensor for the red flower and also same sensor with pink flower... im changing so many phones every year and i can clearly understand what a foto needs! P40 pro with 122 version is less detailed on normal shots than with 112 , i need t use night mode on day light fotos to get some sharpness..
Also the foto you have posted there is no detailed at all i can taje same photo with my xiaomi mia 3 Stock camera apk... and i can get also much better shots withy GCAM on mia 3!

Help! Can someone explain what's going on with my Xperia 5 main camera please???

Hello everyone. Am I alone who is getting horrible photos from the main camera here? It seems that every shot has disgusting blurry smudges at the sides. Basically only central part of the photo is in focus? Is it faulty camera module???!!! Again? If so where is the quality control then? Seriously I can't remember a single flagship smartphone I used to have in the past with such photo "quality"! What's wrong? I can quarantee that there're no dirty fingerprints on the camera glass cover. Please help!
Did you take the pitures in portrait or landscape?
What App did you use?
If you used HDR I would suggest using a tripod to reduce the camera shake
Something like a head on shot of a brick building is more revealing. Make sure to brace the cam for test shots. Dead center focus it.
No lense is consistent throughout its whole field of view. Center softness is the least desirable, edge softness to some degree is normal. The more from the center you can go before blur* increases noticeably the better.
Edge softness can even be desirable at times.
This isn't a 6 optic lense so the degree of compensation for various optical phenomenons is more limited. With lens it's always a compromise with various desirable qualities and the tradeoffs this brings; there is no perfect lense.
To tell if this is a bad copy a side by side comparison with a known good copy is best.
You can always crop it out if it really bugs you...
*see blur charts, which is one of the ways how lens are tested and compared

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.

I know its the lens, I want to know if everyone has it to this level or maybe its just my phone.
Look at the difference with the oneplus, I don't think its acceptable.

You need to compare the same lense/cam model. Go to a store and try a demo or two.
Return it if not satisfied.

Okay maybe I'll try that. A friend of mine has a s21 ultra, they share the same sensor, maybe I should compare with his phone?
BTW is that the quote of Joey from friends ?

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.

Wonder if it just automatically does it now?
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.

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.

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.

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.
