How do you adjust the aperture with the S8 camera?

The aperture like every normal Smartphone camera is fixed and can´t be adjustet.
the fixed aperture of the S8(+) is F1.7.
Or what did you mean?

Xperia Z1 vs Samsung Galaxy Camera S4 Zoom

UPDATE
strong light photos added
Hello all ..,
today i bring you a little comparison of the top 2 i say cameras till now on the market .. Mighty bright Z1 vs Chunky camera zoom
maybe some of you know that i gave my wife the Z1 and got me the S4 zoom cause i was more into more manual control ... any yes its a camera not a phone but with compromising to the form factor.
so today jumped to my mind to do a comparison between both ... how do the Bright f/2.0 lens will match the dim f/3.1 in low light quick snaps ... why in quick snaps because the zoom could manipulate anything u need to give you the type of picture you want BUT in quick snaps you will not stand a time to play with manual settings. so for casual shots which is which ?
it turned out a little surprise ... the Z1 is a very good very good shooters for casual shots.
to make it easy i used manual mode 8mp (to allow over sampling) 16:9 all auto on the Z1 and 4:3 16mp (default) all auto (except some highlighted photos) to the zoom.
so lets roll to the photos ... all low lights
Galaxy Camera Auto settings all ranged between 1/6sec iso1250 while Z1 auto settings ranges from 1/10-1/16 iso400
Dim room
Zoom Auto
Z1 night mode
Zoom auto
Zoom night mode
Z1 3x lossless Zoom Auto 8Mp
Zoom Zoom Auto
Super dim Z1 Night mode 0.8sec iso200 f/2
Here i set the Zoom to same parameters as Z1 0.8sec iso200 but f/3.1 .. see the difference of the wider aperature Amazing
Some Manual adjustments with the Zoom Longer shutter
Z1 3x lossless zoom flash on
Zoom Zoom Auto
Zoom Zoom falsh Off
Strong Artificial light Inca.flour. Tungesten

For me ... Z1 is better in quick snapshots press and shot due to bright f/2 better contrast added sharpness too but the white balance isn't accurate while galaxy camera better white balance the Zoom if played in Expert mode will give u any output u need but u have to know whats ur doin.
I will do some crop vs crop later this night to be added for the comparison

Interesting comparison, are you running the new camera firmware on your z1?
Didnt get it yet still 4.3

The advantage of the s4 zoom is the optical lens, beside that its more or less Equal to other top smart phones on the market today (camera speaking)

Samsung can't make cameras pfttsss
I have the S4 zoom and it is the best when it comes to zoom.All devices that claim "lossless zoom" have some compromise in the image quality while the S4 zoom have optical zoom wich makes it better.Even when compared to Lumia 1520 20mp camera.
The zoom feature on the Z1 is shocking, so much grain it's unreal.
As a point and shoot it's a half decent camera.
In all fairness i'd have my Galaxy Camera over either of them anyday.
Between the two i'd say the Zoom is the better camera.
When you hear 20mp you think this is going to be good, but it does let you down a little when you take a good look at your snaps.

[Q] Decrease camera aperture or increase DOF

The camera on our Note 4 has a fixed aperture of f/2.2, which is a lot compared to standard cameras.
Those familiar with Depth of Field (DOF) will know that such a small aperture gives a very shallow Depth of Field, and it is impossible to take close-up shots of small objects and have the entire scene in focus.
My question is this: how can I increase the Depth of Field of close-up photos taken with the Note 4 ?
Try Camera FV-5
The note 4 doesn't have a variable aperture lens...
Well you already said that the aperture is fixed. Since aperture and sensor size is fixed you cant change the depth of field.
However you can do it artificially with one of Note 4's Selective Focus mode. Since you want to increase the depth of field of close up objects, select "pan focus" when choosing the subject of focus . However it does not work all the time, especially when your "near" object is too close to the camera
Another way is to simply move your phone away from the subject until your background is in focus. then you crop.
To be honest . The DOF of note 4 is not shallow. It's just that the macro performance of note 4 is quite good and you are allowed to get close to your subject while staying in focus.

About Pixel Binning

Is there any way to capture images from the rear 20 MP sensor without pixel binning in daylight? I believe the pixel binning smudges the details a lot. When I use the low light lens from the manual mode in daylight, the details and the overall quality is much lower than the rear 12 MP camera. Is there any way to use the 20 MP sensor without Xiaomi's algorithms?

Wrong thread. Delete please.

Triple camera? More like two...

Hi guys I just found a very strange problem.
I'm on the latest dev xiaomi.eu build.
I just discovered the following.
The wide camera (48mp) does not work.
Actually if I block it with my finger, and change between ultra wide, wide or tele I can still see through camera.
It is like the 48mp camera never used...
for ultra wide, it uses the bottom camera and for 1x & 2x it uses the middle camera.
The upper camera (48mp) is never used... Pictures though are super... is this normal?
The above is if I use the default camera app.
If I use a gcam then
ultra wide is again the bottom camera
1x is the middle camera and 2x is the (48mp) wtf?
Thank you in advance!
Same here! Really strange..... Someone with original rom can confirm this too?

Yes, looks like it's normal...
In MIUI Camera app:
"top" camera is used in "Portrait" mode (= pratically same as 2x with "middle" camera).
"middle" camera is used for 48mp / 1x and 2x
"bottom" camera is used for ultra-wide / 0.6x

It`s because MIUI camera in auto mode uses main sensor for 2x zoom. It does not happen when you choose telephoto in pro mode. Gcam have no such "feature" it seems xd
So if we use xiaomi.eu roms then we do not have the full potential of the camera correct?
The only way to actually use the wide lens is to switch again to global?
Did you try to just replace the cam app from the global?

It`s the same. I am on official global and i confirmed this. It seems it`s intended to be this way by Xiaomi. Also i really doubt you lose much camera potential. Telephoto lens sucks and i wish it to disappear. Waste of space IMO.
Yes I agree with you but from what it seems
It uses the supposedly telephoto for normal and in portrait the 48mp as telephoto.
So we do not actually take pictures with the actual wide... Or the wide is actually the middle cam and they put the 48mp letter to the telephoto?
I'm bloody confused hahaha
They are
Top: 8MP x2
Middle: 48MP x1
Bottom: 13MP x0.6
Letters and colored circle are misleading.
Honestly i only use 1, the main sensor.
The rest are way lower quality sensor.
8MP telephoto is still more detailed than zoom into a 48MP shot.

Thank you, but as I understand it actually uses the middle also when we press the x2 button.
The only way to use the actual telephoto is through the pro settings.

I also only use the main sensor and sometimes the ultrawide.

Probably you are right. I never take zoomed photos though so I can't really say.

Absolutely right!
It's very funny to read in some test articles for 9T that the top sensor is the Sony with 48MP.
It's also very astonishing that Xiaomi tries to let people think the upper camera is the flagship by printing 48MP next to it and paint the upper glas-ring in pretty red color (for the black model).
With global rom and stock camera app the behavior is like that:
In Auto-Photo mode:
0.6 - 0.9 Bottom Super-Wide-Lens
1.0 - 1.9 Middle 48MP Sony Wide-Lens
2.0 - max Top Tele-Lens
You can see the change of lens and also the change of color in the fiewfinder by zooming with 2 fingers from 1.9 to 2.0
In Pro-Mode:
If you choose Main-Sensor (Middle Sony Wide-Lens) you can zoom to max without switching to Tele-Lens.
In Portrait-Mode:
The top Tele-Lens is used for the picture and the middle Main-Lens is for bokeh-effect.
You can test it by taking a portrait-mode picture while putting your finger on the middle lens. Result will be a portrait picture without bokeh-effect.
Did a few tests with gcam/stock camera, to analyze the "usefulness" of the 8mp telephoto compared to main 48mp one, in a static and detailed scene
comparing a 8mp with a 12mp "resized" to match zoom size = 8MP is MUCH better and more detailed
comparing a 8mp with a 12mp zoomed 2x in camera to match zoom size = 8MP is MUCH better and more detailed
comparing a 8mp with a 48mp "resized" to match zoom size = 8MP is still better and more detailed
comparing a 8mp with a 48mp "resized" RAW to match zoom size = 8MP is still better, the raw one is "90%" there
so the 8MP tele camera is super useful and provide better image than any method of zooming the 48MP, unless you are taking 48MP RAW all the time. If you are using JPG, the telephoto is amazing. That's why the stock camera use the telephoto when zooming in good light conditions, but switch to the main camera when there is less light (it is better to have a less detailed and cleaner image than more detailed and noisier one, and the telephoto is very noisy in low light)
if anyone want it, i can provide 100% crop samples.

Camera Resolution

Been playing around with camera resolution and I understand that while the actual sensor is 48MP OP defaults it to 12MP to "capture" more details (I think thing the 48MP setting provides better shots but that's subjective).
Now the question/issue that I have is when looking in Google Photos (gallery) the shots are being reported at various resolutions... most of the time not close to the 12MP that the sensor is supposed to capture the image at.
Regular lense, showing as 7.2MP --- 4000x1800 resolution (setting in Camera app is 12MP - 6.59mm)
Wide lense, showing 7.2MP --- 4000x1800 resolution (setting in Camera app is 12MP - 3.05mm)
Tele lense, showing 4.8MP --- 3264x1472 resolution (6.95mm)
Bokeh shots appear to be showing higher res, like 13MP.
Pictures taken from my old Pixel 2XL show consistently 12.2MP which I believe is the sensor size so I'm trying to figure out what setting may be affecting the resolution. File size are significantly smaller on the 7.2MP shots so I'm sure I'm losing some quality here.
Switch to 4:3.
You are shooting in 20:9 hence the lower resolution.
Perfect ty. I did select full looks like. Went back to 4:3 and seems to show the correct mp.

is there a way to fix it to provide 16:9?
