How the dual camera works? - Honor 8 Pro Questions & Answers

How dual camera works? I heard that one camera is color and another monochrome so I tried covering one of the lens but the camera app seems to get the image only from one of the camera while the other one is off.
It's interesting...

While using the wide aperture mode, it needs both cameras so as to get an idea of depth.
While using normal mode, it uses the monochrome sensor to get more light and details. Then it mixes them up with the color image to get an image with higher dynamic range and greater clarity.

[q] front camera

if i try taking a picture using my front camera, its really blurred... is it normal?, because i had some phones before that only have VGA Frontal Camera but the images seems to be fine...
i know that we have a great Main camera, but there will be times that you need to use this front camera especially if no one will took picture of you *with you're friends/gf* LOL.. because its hard to use main camera since there's no camera button...

You probably need to get in there with a cotton bud.
You can always use the main camera with a 3 or 10 second timer.

i already did clean the lens... crystal clear but still its worst than most of VGA frontal cam?
thanks for the advice about the timer, but i'm still hoping for much better frontal cam...
The front camera is garbage. Mine makes me look bright pink! The main camera quality is also pretty average, I find it no better than my old Desire HD.

will there be an app or ROM that can fix this?
sometimes there are bits of violet color, which make me look like barney.. LOL
For the red tinge, try dropping the saturation to -1. I don't have any focus problems tho.
cleaning the lens worked for me

my front cam looked really horrible for a while... blurry, tint was way off, grainy, lots of artifacts. cleaning the recessed lens definitely did the trick for me.
Make sure you're well lit. Here's a sample from my camera for the quality you should expect.

Discovered a Camera (front) trick....

Everyone knows the weakness behind our Back Camera.. but does everyone know how POWERFUL our front facing camera is? I bet you didn't know you can crank the ISO to 12446 on the front facing camera
You can now take selfies in almost pitch black rooms (and come out grainy, but visible).
Inside the "Selfie" mode, click on EV +2 and go into a dark room.
Your image will automatically being super grainy but you'll be able to see yourself like no other!

Yes...it's weird it only works on front camera and not on regular one...but yeah! Takes photos on pitch black room
Does anyone know if the rear facing camera has an IR filter on it? That may explain this, because if the rear facing camera has a filter but the selfie one does not, the selfie camera will let in more "light", and use ambient IR to illuminate your face slightly more. That's just my best guess.

The reason you can do this with the front is because the camera used is exactly the 4UP sensor from the M8 which has larger pixels for better low light performance

Xiaomi mi6 optical zoom is actually digital?

Hello guys,
Ive been playing with my mi6 for a while and noticed a strange thing. Photos captured at 2x look actually more like a digital zoom than an optical, even though the resolution is the same as 1x. When you actually cover the left camera lens, the picture is still normal. No matter if you choose 1x or 2x.
Any ideas?
Thanks in advance.
You can explicitly set the lens on manual mode.

Thanks, you da real MVP!
Where can you change that? Still on MIUI8.
it does that in low light shots, cause the tele lens is so bad at low light that it prefers to shot in main camera and zoom it in.
sources : miui forum? red it when i bought it

That's right, the telephoto sensor has 1.00µm pixel size at f/2.6 aperture, while the main sensor has 1.25µm pixel size at f/1.8 aperture.

Dual Camera Implementation

Hi
Just wondering, when will the monochrome camera of the two cameras be used in real life scenario.
1.Will it always be used along with colour camera?
2.Will it be used when recording video?
I know wide aperture mode will definitely use both cameras. But for normal photos when I blocked monochrome camera, the colour camera still takes the same picture quality.
It can be used alone, and yes it is used to work with the RGB sensor, as for videos, they both work at the same time

While clicking normal pictures, both sensors are used. The monochrome sensor captures more light and hence, used for improving the shadows and details in a picture.
I haven't blocked the monochrome sensor while taking regular pictures.
If you did, then do post some samples of both scenarios.

Can we see a sample photo? One using both cameras and one blocking the monochrome sensor.
Yes, attaching the pics. One with both cameras unblocked. One with monochrome blocked. I don't see any difference in the camera settings, resolution, and quality. This is taken in normal photo mode.
Pic 1 is monochrome blocked.
The difference might be noticeable in low light conditions

I can see the minute difference. The one with unblocked monochrome sensor is a bit brighter than the one with blocked monochrome sensor.
The different isn't much noticeable here but it surely will be in low light conditions or scenes with high dynamic range.

At first glance, the difference is prominent. Left picture is brighter.
I dont see much difference betweeen the two pictures as such as the monochrome sensor is advertised as a big deal. But really we need more samples. I will do what I can when I get time.
Ultimately, I believe that the RGB camera is a real good one as we are getting good pictures out of the single camera! That's nice.

I have heard it's much better using the B&W sensor to take pictures in lowlight situations.

Question What is the zoom lens for?

Hi all. I am debating the switch from the regular 6 to the pro.
Looks I will be getting bigger higher refresh screen (pro) which is curved (con) and with worse battery life.
One thing that is not clear to me - is the zoom lens used in any other situations than when actively selecting it? For example - which of the lenses is being used when you select the portrait mode in the camera app? Is it using the telephoto lens to battle the fish eye effect?

I have never gotten the telephoto lens to show up in gcam. Only the 50MP wide cam and the 12MP ultra wide cam. The 50 gives you zoom options but the 48MP telephoto never shows up

It's a 4x telephoto, which is a lot for portraits (so portraits are taken using main camera at 2x magnification).
No, it's not being used for enhancing ultrawide. I suppose it's also because if the same reason mentioned above (OnePlus uses it's 2x tele for this as well).
Telephoto is really only useful for zooming 4x and up all the way to 20x, when photos are still kinda useful (depending on a scenario), thanks to being a 50 MP sensor and some Google's AI magic.
I take a lot of zoomed pictures and I don't mind curved display. Battery is okay, 6 hours of SOT are real for me, usually on social networks and news scrolling. Sometimes I play a League of Legends, than it will drop to 4-5 hours.
Zoom lens is for... zooming in. I would think that would be self-explanatory?
It kicks in when the magnification reaches about 4.5x. Switching between sensors is exclusively a matter of changing the magnification level, not by "selecting" a particular camera. There are other details considered before switching sensors, such as exposure requirements.
You can tell which sensor is in use by briefly blocking sensors with your finger. When you see your finger on the screen, you found the sensor that is in use.
Yeah, thanks
What was not clear to me was if it is being used when shooting portrait photos, as some phones (e.g. Oneplus) do.
Looks like this is not the case.
I will stick with my vanilla 6 then, not missing out on much, subjectively.

Portrait photos can be made with ANY lens, depending on the distance and direction to the subject(s).

Is it so? How does the portrait UI looks on Pixel 6 Pro? On the vanilla pixel I have the options to shoot it in 1x and 2x only. Does the pro version offer a higher magnification, using the zoom lens instead of main one?

No. 1x and 2x are the only options available. The telephoto lens isn't used in portrait mode.
