After taking a few pictures with the tele camera I noticed some really weird artifacts. After testing a little bit more I noticed that the tele camera is not always used.
So today I did some controlled tests. Set up a close scene, took a picture with the wide camera (from approx 25 cm), switched to 2x, then switched back to 1x and zoomed in by getting the phone closed.
While I was taking the 2nd picture the phone was clearly switching between cropping the wide camera and using the tele camera (with a slight change in frame size and angle).
The result is that many times the phone uses only the wide camera or switches to the tele camera at will, without providing any information to the user. Accordingly, one's pictures might only be cropped versions of the data from the wide camera, with the inherited artifacts.
Am I the only one noticing this?
Here are the three pics:

PS: The phone is running Oxygen OS v4.5.10
redo the test.
A guy did a lot of test on a tri-pod and then compared the pictures very closely on a computer.
Both camera are always used, but most of the time one add a little bit of sharpness in the picture.
Not because you cover on lens, that it means it's not working. It only means that the pictures wont be as sharp, but the difference is very minimal.
Here how it works;
In good light conditions, the 20Mp sensor is used for the x2 zoom. It does not switch to 16Mp. On the other hand as soon as the light becomes insufficient it switches on the 16Mp to zoom at x2. And uses the 20Mp to improve the photo; giving it more details.
When the light condition is average and the 20Mp is hidden, at this time it switches to the 16Mp, but without hiding it, it stays on the 20Mp and uses the 16 for more detail and exposure.
This as been said, in some condition, such as very dark scene, the 20mp, could not be used at all, hard to see since the pictures are too dark.
Has anyone found out how to decouple the two back cameras on stock oos?
Sometimes I'd like to make that lens choice myself, but still be able to use the OOS Camera at other times.
On stock, the two back cameras behave as one with all the third party apps I've tried.
On custom ROMs, the phone shows three cameras.
Hi
I'm not sure if the Galaxy S8 is able to do this but how can you get DSLR style focus where a subject/ person is in focus and background blurry? Can the rear camera do this as well as selfie cam? I haven't seen any options for it.
Seems only the Note 8 has this (or iPhone X, Google Pixel 2)?
Note 8 has second cam, which is x2 telephoto lens, so already has shallower focus depth and rest is done with software. S8 does not have second cam.
And here is the problem: blurred background, called bokeh, is mostly used in portrait photography. Wide angle cams so commonly used on phones should not be used for portrait photography, because due to wide field of view being projected on flat surface you get big distortions and wrong proportion, like big nose for example. Check fish eye lens pictures to see this distortion effect fully. So while you could distort background and make portrait photo with standard phone lens like s8 have, it would look silly. Outside of portrait photos I don't see much use for shallow depth of field, but if you're so inclined you could experiment with photo editing software like photoshop and create same effect. Expect S9 to have dual lens and portrait capability in about 6 months or get Note 8 now if you really want it.

there's an app that does this function very well. AfterFocus. the pro version lets you save in original quality. It only takes a few minutes to get the same result from dual camera devices.
Selective Focus is one of the camera modes out of the box. That is what you are looking for.
I have an S8 and have tried the selective focus mode, which works relatively well as long as the object stays still long enough, however I was reading an article about the Pixel 2 this morning and this extract made me hope that Samsung can also follow Google
"The single-lens portrait mode photos were made possible by its adoption of a dual-pixel sensor - meaning each pixel can be used to both record the image and determine focus rather than just one or the other.
Some of Samsung's handsets already feature the technology, but Google has built on it with proprietary software to make it possible to create a depth map for photos, which can be used to add special effects."
I hope that Samsung can improve the selective mode for the rear camera as the S8 also has a dual-pixel set up, unfortunately the front camera doesn't have dual-pixels
Another thing is I'm hoping that the Google Camera app, which I have running on my S8, should get an update to support this....fingers crossed.
Hi All,
It seems that the 5T has a low light shooting preference over telephoto and facial unlock.
Although the latter is not something I'd ever use, I was thinking would it be possible for the camera's on the 5 to use the low light functionality of the 5T? I've read that they're similar?
If not, it's not the end of the world, I've took some great pics with my 1+ but if I could improve low light then it'd be a bonus.
I believe the 5T has a different camera sensor.
If that's the case, it won't be portable unless you change the camera altogether.
The primary camera is the same, the difference is on the second camera. Now its nos a zoom len, it will work for low Light shoots because the sensor has a different aperture.
The 5 has de 1.6x len zoom, now on the 5T, all the zoom is digital

Actually I think OP5 is doing the same thing (obviously with different second camera sensor) test yourself: open camera app, cover the main camera and obviously you will see just black, here is the weird thing: change to "zoom" (2x), cover the second camera (supposed zoom lens) you'll still have image then cover the main camera boom no image! So for 2x is just a digital zoom (a good one) from the main camera, and the second camera is just used for portrait mode effect
I think this is only in low light condition. Try this again in good light and it would work as expected
google cam with HDR+ will give you better low light shots
i took a picture of the night sky the other day and it actually turned out a beautiful picture. very surprised how well it judged exposure time.
We need to wait OxygenOS 4.7 to discover how many new features will arrive also in our OnePlus 5.

Focus on Google cam never works for me I've missed countless shots putting my faith in that
For the most part Google's Camera is awful.

Yep that's what I wrote mate.
Telephoto Vs low light I know they're different.. I'm wondering if the software can be forced to work with what we have?

?? Oreo had nothing to do with what I've asked.?
I only need to know if the camera choice!! Low light over zoom can be transferred. In all honesty the second camera never works. Cover it an nothing happens.
In low light the second camera doesn't work, and it's better that way. With an f/2.6 aperture, it just wouldn't allow enough light in to the tiny sensor to be useful. This would be true even with the pixel binning technique the 5T uses for its secondary camera.
It's also entirely possible that there's hardware involved for that feature to work properly too.

Unbelievable bull crap from a senior member. This untrue.
Second lens activates in good looking lighting automatically, you covered the lens manually so it thinks it's dark and it will take the picture with main lens.
Best way to test is to test outside, I can visually see, how it's jumping from one lens to another when zooming. Also you can see whether it used the second lens from the photo details.
You don't need to be rude dude... Yes I'm senior member but I'm not a God that know how everything works, I just did that test and see that results, didn't know how this dual camera works. So I researched a bit and found what you said. My bad
Here's a video to understand how this dual camera works
Cheers

Not likely since you have to have a lower aperture (1.7 or so) a Tele lens aperture is usually higher and allows less light to reach the sensor. With this, it is highly unlikely to have a software update that will allow the 5 to reproduce the 5T's low light photo quality.

OxygenOS 4.7 is not Oreo, is the default ROM installed in OnePlus 5T (OnePlus 5 has OxygenOS 4.5)

I noticed on the mi 9 camera there is a macro mode available, however, I have not been able to find a macro mode on my Mi 9T. Does anybody know how I can enable this?
Anyone?
well, it is not there, so how can you enable it? Mi9T camera doesnt support macro mode - at least in this version available. Maybe in future, who knows?
Mi 9 has auto focus on it's ultra wide camera allowing it to focus on very close objects, which is what you need to make macro shots (there's also the option of a dedicated macro camera that some huawei phones have). Mi 9T's ultra wide camera has no auto focus, which means no macro mode.

Despite I have no clue, why anyone would use a (the) ultra-wide-angle lens for a macro shot (impractical focal length and inferior sensor) - the Mi9T has a macro mode (main & tele) - though the minimal focus distance is not that impressive.
Stock cam > PRO mode > enable 48MP (for best quality, tele sucks due to inferior sensor) > set "F" to a value of "40" or below > "M" turns into a flower - and now you can even enable focus peaking (top bar).
From my experience it's basically the same as using the main 48MP mode - but with a huge advantage: the ability to set/lock the focus to a certain (minimal) distance (and focus peaking).
edit: focus peaking disables itself, when switching to 48MP - vice versa
edit2: tele lens is basically completely useless
edit3: autofocus needed for macro - hilarious

Yeah but that doesn't improve the minimal focus distance. I had a mate 20 pro and that phone was able to focus on objects as close as 2.5 cm with it's ultra-wide camera. But if it's good enough for you then use it.

Yes, I agree - having a macro mode is to a certain degree useless considering the minimum focal distance of Mi9T's lenses (which has nothing to do with the lack of auto-focus).

I can see it really bothers you that i was wrong about certain things. I apologize for it, i wasn't aware. Never cared much about photography, which explains why i ditched the Mate 20 Pro. Anyway, thanks for pointing it out, i "fixed" my original post.
Hi.
I was wondering if there's a possibility to actually take pictures with the 2nd "depth" sensor camera on the S10 Plus. I know for a fact that the stock camera App doesn't let you use it, other than to assist the primary camera for the "Live Focus" mode.
Nonetheless, if you type *#0*# on the phone App, you can access a test menu, in which you can actually take pictures and see the difference between these 2 front cameras.
I've attached 2 examples that I took, there you can appreciate that the second camera actually has a considerable wider field of view (in comparison to the primary one, though the quality is inferior), which would be really useful for group selfies, since the "Wide Selfie Mode" from the S9 was removed for some reason.
It would be awesome if someone finds a way to use the 2nd front camera to take wider selfies-
is there no possible way to use the wider front camera? (depth sensor), it would be a bummer since it has nearly the same field of view as the ultra wide angle selfie cam on the LG V50.
Additionally, is there a way to recover the ultra wide selfies mode from the S8?
There has to be a way to use the 2nd camera. As for wide selfie mode, there's probably an app or theme out that lets you do it, but I am not sure.

Yeah, my thoughts exactly, but there's also a possibility that Samsung is not providing any API to access the 2nd front camera, which would be a real shame.
