Does S20's camera really contain 64 MP? - Samsung Galaxy S20 / S20+ / S20 Ultra Questions &

In S20, when u set the camera for 3:4 64 MP, the zoom goes only upto 6X. In other settings using 12/9 MP, it goes all the way upto 30X.
Now, when you have 64 MP at your disposal, this format should be more amenable for 30X than 12 or 9 MP format.
Further, I find that 64 MP, 6X does not produce any better image than 12MP, 6X. After 6X, the resultant image with 12 MP contains 2MP & with 64 MP, it should contain 64/6 = 10.6 MP (if it is a crop) & so the latter is expected to show much greater detail without pixelisation. But actually it's not so.
And even after 6X, the file shows the picture contains 64 MP. How's it so? From the quality, it appears like a digital crop rather than optical zoom.
I really doubt if it contains 64 MP.
Did any of u guys observe this?

Think the sensor is definitely 64mp (without zooming in at all), but as soon as you zoom etc it behaves in a hybrid manner, not in a typical cropping manner.

Well, sometimes cameras marked as 12MP are actually higher MP sensor, but they take for example a 16MP image, and reduce it to 12MP and mark that as a 12MP sensor, this way they can get better images
I think that's not the case on the 64MP, it's REALLY 64MP and they didn't cheat anywhere, so if you take a 12MP section of the 64MP base it's not so great because it's not like a smaller sensor where it's cropped intentionally.*
In fact, digital zooming have the advantage of being able to have use of the whole sensor if you want to, and therefor get extreme good quality images, but when zooming in it's never as a good as an optical zoom

Tilt2 camera?....

Ok, this camera states its 3.2 megapixels. But the picture quality is worse than the one from my old phone which had only 2 megapixels. Do I need to change the settings or anything?
Megapixels have nothing to do with quality, only size. Make sure you have the largest resolution picked and that it is set to SuperFine. Still, the camera on the TP2 is only so-so.
Wow thats stupid. I don't like the camera at all.
Picture quality also depends on the camera lenses used. HTC doesn't really use great lenses.
Sony Ericsson (I had the SE C702 CyberShot phone before) uses very-high-quality camera lenses, and the pictures it produced were great!

Well, if you have a 8MP camera vs. a 3.2MP camera taking the same exact photo, and you were to print a 3x5" photo from each, the 8MP should still give you better quality than the 3.2MP. The 8MP camera is able to produce 8 mil. pixels whereas the 3.2MP camera can only produce 3.2 mil. pixels. If you were to print the 3x5" photo, the more pixels, the clearer the image.

Again, that's not a quality issue, per se. Anytime you increase the size of a photo without increasing the number of pixels used to display it, the pic will suffer because things like compression artifacts and aliasing will be more pronounced and visible. Not that these things aren't present in both the 3mp and the 8mp images, they will just be more noticeable in the 3mp image that is displayed at the same size as the 8mp image. That's the real value of more megapixels, the ability to increase print or display size without the ill effects. But that has little to do with quality.
I've been a pro photog for the past 18 years and shooting digitally for magazines since 1997. I started with a sub-1mp camera back then and the quality was fine, but the low pixel count limited our ability to use digital pics for more than just 1/4 page shots or smaller. By the time we got to 4mp cameras we were using them for full page spreads without issue. An 8mp camera can now yield a decent two-page spread. Still, the quality of pics hasn't been increased with more megapixels, only our ability to display them at larger print sizes.
It's easy to confuse megapixels with quality and manufacturers share much of the blame for convincing consumers that more mp=better quality with their sales shtick, but when you understand that quality is not necessarily tied to size, you realize that application is the main factor. For instance a 2mp camera can shoot very high quality 4X6 photos, but blowing those same pics up to 8X10 will reveal the weakness in megapixels, not quality. At the optimum size for a particular mp format, more mp does not yield higher quality, only higher storage and processing needs. It will give you more flexibility in cropping if your skills with the camera are lacking, and more format choices when printing, but not higher quality.
So how would I get the best quality out of my camera?
Have you installed the cab that gives you more camera settings? It gives you a SuperFine setting unavailable on the stock setup. Do a search for it. Also, make sure the lens is clean. Handling the phone often causes fingerprints and smudges on the lens that reduce photo quality.
Thank you so much, do you have a link or know the name of it?
The one I found is ExtraCameraModes.cab.
Here ya go.
Ok, it didn't change anything haha. But thanks anyways
I thought it comes with Super Fine by default. Anyway, I've always had to play around with the light settings the get the color I wanted. I set the ISO at 200. And lighting also takes a toll on the quality of the picture.
Anyway, the camera sucks. i wish they had a button to turn off auto focusing when i need to take quick shots lol
Cameras on cell phones are more of a convenience than a sophisticated capture device. While some actually take fairly good photos, I wouldn't expect too much from any of them. They certainly aren't designed to replace a good point-and-shoot.
OK, well thanks for the help everyone!

Difference between the camera MP?

I cant seem to differentiate between 12mp and the 16mp other than the ratio size. I cannot notice any drop in the quality when viewing the pictures normally and zoomed in from my phone or maybe I think my eyesight is pretty bad . Can someone help me over here?:fingers-crossed:
Megapixels doesnt influence the picture quality of a camera, its sensor does. megapixels determine the size of your picture so for eg you can have a 50 megapixel camera but if the sensor is bad you wont get a good picture and vice versa, which is the reason that older dslr and point and shoot camera's still out perform many modern day phones because they had big sensors specially the dslrs. until and unless you are going to print posters and heavily zoom and crop a picture 12, 16 or 20 megapixel is more than enough.

A70 camera is not true 32 MP, it´s 4x8 computed 32MP.

Many of the cheaper phones which claim to have 48 MP cameras use an interpolated solution to provide a 4x12 MP image. I can excuse companies to use this method on very cheap phones.
Samsung uses (Tetracell) technology from late 2018 to create a hardware computed 8x4 image while claiming to have a 32 MP camera, this clearly shows when zooming in to crop an image, the blur is real unlike my S8+ f.ex. which actually only has a 12 MP camera. I want to shoot 16:9 photos and these are strictly limited to 8 MP, 4:3H does produce 4x8 but it´s still nowhere near the quality of the S8+ 12 MP camera. I was naive to think that Samsung wouldn´t pull a trick like this on their customers, the shots at low light clearly show the limitations of the camera.
I called Samsung support in Denmark and explained the problem, the lady told me I could choose whatever picture size I wanted in any aspect ratio.... she told me to wait as she was going to find out how, she came back 5 minutes later and told me she couldn´t do it on her models ... of course not, I already knew that. I left her my email because she asked .... not going to do any good.
The pictures are nice for the most part ... just don´t zoom. My Umidigi F1 for 180 dollars takes overall worse pictures but the zooming is far better on pictures as the lines are straight without blur regardless of how much I zoom in, it does not have any low light capability however.
PS: HW sensors will report the cameras as 8 MP because they don´t understand the 4x8 technology. As it is I believe all third party camera apps will detect the same and be limited to 8 MP.

32 MP GCam ?

Does anyone have by any chance found a way to produce 32 MP shots using GCam ? I can't Invision the amount of details that would appear in the picture ,I searched everywhere and I am desperate for such mode ,even if the picture is just interpoalted
Thanks in advance ,have a nice day ?
Everybody Needs GCam For A70.
Everyone who have A70, needs GCam with proper cameras.
Rear : 32MP
Front: 32MP
Somebody says that samsung and other phones like Xiaomi, Oneplus, Realme etc. are using 4x technology. Means rendering image at 4x.
Redmi 7 Note Pro has 48 MP but it actually has 12MP camera means 4x12= 48MP.
Same case in other phones. Like realme 3 pro has 16MP camera but click 64mp ultra pic too.
Listen, If we are thinking like this 4x technology. Then Gcam shows rear camera = 8MP means 4x8=32MP. Means it's true.
But But But... In case of front camera why it shows 5.1 MP? means 5.1X4 =20.4 MP ? Strange!!!!!!!!
If 4x is used then why front camera shows 5.1 MP even it's also 32MP.
I am very sad because there is no developer, who shows interest in custom ROMS, Mods, GCam, TWRP etc. for Samsung A70.
I will wait for some days and then try to sale my A70.
Thanks.
If I'm not mistaken the camera has 4x8MP sensors and the gcam can only see one of them , the front camera is another issue and it mainly has to do with the way gcam is made. If anyone knows better please inform us.
8MP on the front, 5MP depth sensor, 8MP ultrawide and 32MP regular on the back. The 32MP sensor is a Samsung ISOCELL sensor that uses 2x2 pixel binning (basically 4 cells = 1 pixel) to produce a binned 8MP image.
Samsung's 12MP mode is curious, it's not really needed. Gcam produces better images at 8MP than Samsung's own camera software does at 12MP. Samsung's app is garbage, basically.
Samaung dont make all their camera modes available in public APIs and until that changes gcam will likely never fully support any Samsung phone.

64MP Sensor

Hi all,
I've read online that the 64MP telephoto sensor actually has a wide lens but takes a 16MP crop. Is this true? If so, that means photos from the tele lens would be 16MP 0.8µm which seems like a massive step backwards.
My questions are:
1.) Can anyone confirm if this is correct?
2.) Does the S20+ allow you to take full sized 64MP photos with no crop or will a 3rd party camera app allow it?
3.) Can a camera app be modded to take 16MP photos at the wide angle using pixel binning with 4 pixels into one to make 16PM 1.6µm photos?
Thanks,
Kris
This is a picture straight from 64MP Camera I didn't check for wide angel outside of normal photos

Yeah, I can confirm this....the zoom isn't that impressive in my opinion but at least you have an option of taking a full 64mpx photo for extra crop if needed and if main lens is unable to.
3x is where this phone maxes out per my tests.
Also native camera allows to take full 64mpx photos.
How this 64 Mpix mode is behaving with close objects? Is it have bettery sharpness on corners when compare to main 12 Mpix Wide camera?
