You cannot complain about something than not back it up with examples.

Show me some examples of good photos taken with another smartphone to back up your claims the S21 U is a bad camera system.

Am not talking about pictures of a sofa, but actual good photos you have taken with a better smart phone camera system. Talk is cheap, so follow up with real action please.
It's not a competition, relax. I own the same phone as you and I find it excellent from all points of view. However, if you don't see certain defects in the photos, I can't help you. If you want to see what a similar sensor can do with a gcam, I'll post you another link. With good software this phone allows you to leave a compact camera at home so i want it.

what is possible to do with a Samsung ISOCELL HM2: gallery


What are the problems with Samsung stock app and ISOCELL HM3 :

It's not about my work... It's about the difference between decent and very good. In all of your pictures, if you zoom a Little bit you can see agressive oversharpening and a lot of noise and aliasing. I've got the same problems with my s21 ultra. I Hope Samsung Will fix it
Lol nobody zooms in that much. You'll see the same results with any smartphone.

They're all raw shots from the Xiaomi as well as the use of gcam? Irrelevant

Eh what? You don't need to zoom on the 10x photos to see the sharpening artifacts if you're viewing them on a PC. They look unnatural because of it. Only on a small screen like a phone they look sharp.

Don't get why some people take criticism of the image processing like it's some personal insult or battle of photography skills.

Sorry but where's the oversharpening ? I don't see it, especially not on my snapdragon model.

They're more than good enough for social media and as good as any other phone including the p40 pro plus which is the only other phone that comes close in zoom quality. There isn't many phones out there that don't overprocess their telephoto shots.

Pretty good photos there. but try outdoors. I find outdoors with sunlight and bright sky behind the trees, is where things look weird. Low contrast backgrounds tend to look better.
Your 3rd picture definitely shows it though, has a bit of an oil painting look when viewed on a monitor (27 inch 1440p or 34 inch ultrawide 1440p in my case, 1080p probably wouldn't have the resolution for it to matter).

I'm still on the Feb AUB9 software with an Exynos phone, maybe March sw improves this.

I've attached two photos I've taken that I think demonstrate this well. You can see it just does not have the resolution to capture the radio tower properly and the upscaling + sharpening has just made it look strange, and you can see a faint white outline on the hill due to the sharpening.

The other one is not too bad but has a weird unnatural look to it, which I think again is over-sharpening. Trees in sunlight seem to demonstrate the unnatural sharpening most clearly.

You don't seem to understand anything about photography, have you seen the 100% crop of the canvas print I have on my wall taken using a DSLR??

The subject matter isn't even in focus, yet when printed on to canvas it looks fine.

No one views photos at 100% crop unless you are a pro making a living from selling photos, in which case buy a DSLR.

The S21 U lets you take amazing photos in nearly all conditions for a huge number of subject matters. To moan about the photo quality at 100% is like moaning F1 cars have too big a turning circle.

No camera system perfect, not even the £6k Sony A1.

Don't forget this is a camera PHONE, in addition to taking photos at 240mm zoom it also plays games, does calls, internet banking etc. Frankly I find it amazingly the S21 U can produce any images in the some of the situations I've tried to use it, let alone good ones.

I sometimes wonder if some users are intentionally ignoring some of the posts, to avoid challenge of their believes.

What's your point? You able to get good photos in some specific situations means all criticisms are invalid? Way to bury your head in the sand.

Your problem there is the ISP the Exynos just tends to overcompensate by the lack of detail it can gather compared to the snapdragon by upping digital sharpening

Yeah it does sound like it's worse with the Exynos :( Hopefully it's better when I finally get the March update. Since New Zealand seems to get updates just about last, i suppose I'll see it at the end of the month.

No it doesn't mean that, i understand that you might have some issues, but daylight zoom photos are not part of it, they are the strongest aspect of the camera. Try to drop the exposure/lock the focus before taking shots, and turn off scene optimizer and stand still.

Also you said try outdoors, i posted 2 great outdoors 10x zoom photos, and i got plenty others. BTW for your and anyone else info, based on tests from day 1 till now, Exynos has a lead in zoom, so if you say its Exynos, it is worst on Snapdragon, so please get better informed.

Snapdragon = better video
Exynos = better zoom

So you are sayin that no One open at 100% a 12mp picture on a monitor or TV screen right? then for me it is useless to continue arguing.

Actually yours pictures are the only One that look really good with 10x. If you can do something like that outdoor i really appreciate. I keep saying that the sensor is very good the problem is the software and these photos show me that thanks

Its only an argument if there is something worth arguing about.....

You keep on saying the sensor is amazing but the software is bad, why do you think Samsung has developed the software as it is??

Take at look at the Sony A1 versus S21 U video, that A1 is delivering results using a 'good' sensor which happens to be nearly 1/4 the size of a S21 U display.

The reason Samsung HAVE to use software processing is because apart from the main 108MB sensor the rest of sensors on the S21 U are what you expect from a smart phone.

If you don't believe me, take a RAW shot on the UW sensor with ISO of 100. You will see noise in there than a DSLR camera at ISO 1600+.

Without software processing the other sensors deliver unusable photos. Someone here posted a zoomed RAW shot a while ago, the noise was horrific even in bright day light.

You cannot have everything in life, I personally will take processing and the photo quality the S21 U delivers versus a RAW file that I would have to spend ages post processing, and that's before you even consider how the S21 U delivers its amazing dynamic range......Its not the sensor doing the magic, its the software.

What's really interesting with the A1 comparison isn't just how close the photos look, but the fact with the A1 you will need a separate laptop, software, internet connection, back up solution to actually manage photos and see them.

On the S21 U I can shoot, review, edit, share, backup in one device on the go. Not forgetting all other things the S21 U can do in addition. In comparison to the Sony A1 the S21 U is a bargain and all the camera most people will ever need!

have you ever owned the device or do you speak by hearsay ?. i now have s21 ultra and i wouldn't change it for anyone, being the most complete device on the market. but the photo compartment has to be fixed. the problem is the software since the sensor is excellent. This is taken with the p40 pro + 10x, impossible to achieve with the s21 ultra (look at the details). we have to expect something similar from Samsung.


first of all that picture is horrible and if you cant produce this picture with s21 ultra then return it. something is wrong.
couple of pages back i shared a picture with 30x zoom with more details!!

and Yes, I owned the device and ITS HORRIBLE !!! the worst camera experience i had on a phone with "Potential"
Check some videos i took on YouTube with many devices including xiaomi mi 10 mi 10 ultra p40 pro plus and even vivo x50 pro plus! so actually the answer is yes i know what i am talking about :)


Now back to the P40 pro plus.
the worst device with ZOOM no matter what DXomark is telling you ! jumping jacks while zooming in video check that in my moon shot video using the device. then compare it to zooming in video using the mi 10 ultra and vivo x50Pro+ ! the difference is huge its not even funny

darkest and most grainy pictures when its less than ideal conditions.
worthless color science in dark mood compared to anything before the RYYB joke they came up with since the P30, am i wrong ?

Technology spoiled us maybe but long story short, the best camera always will be pixel phones followed by iPhones, and samsungs now, Huawei can kiss the dust.

Are you claiming that vivo x50 pro plus has better zoom and zoom video vs Ultra?

    My S21U is simply the best photography tool I have ever used. Snapped this the other day at the park when my daughter was playing with her friends.

    Kids sitting down having a discussion about Corona virus rather than running around, hopefully its a story we can forget soon (In the UK anyways).

    I don't play with post processing much these days, but AD Photoshop/LR on the mobile is surprisingly good, this is going to be printed to acrylic plate at somepoint.

    51020901102_33a0501883_c_d.jpg


    The dynamic range of the S21U really is quite something, even jpgs allows for post processing to the exact temperature 'look' you want.

    The depth and general tone of pictures the S21 U is able to capture really did use to be only possible on 'proper' camera systems, even the x10 lens produces half decent efforts in post.

    Add in the fact the entire work flow is possible on the phone, so no peeking on the back of a LCD camera screen, no faff with uploading to a laptop, no LR library to manage, no need to worry about backup due to the cloud, am pretty sure I can also send these file direct to Photobox/Snapfish or similar for large format printing all from the phone.......

    From a purely a photography point of view, the S21 U is outstanding, there is no other way to put it.
