Hey,
I was really wondering if the back cameras are actually helping the picture quality at all.
I have tried using different camera apps and covering some of the lenses and the picture/video quality seems always to be the same even if it's only 1 lense uncovered.
Can someone confirm/deny?
IMHO pretty useless, but you should see difference in portrait mode, where background is blurry when additional modules work and sharp when are covered.
Uhm.... you have 3 Back Cameras.
1 is Normal Mode 48mp or rather 12mp with Quad Bayer raster.
2 is wide Angle which has bigger FoV
3 is Macro Lens.
And only one camera is used at a time.
Only exception is the ToF Sensor that looks like a camera but only brings Depth infos for focus.
IMHO best Camera Quality comes with Google Camera mod and a custom XML.

Hi Guys,
I asked myself how the zoom on my Z3 should work.
As far as I know, the Z3 can Zoom into the sensor while taking 8mpix pictures.
While I tried it, it seemed to me that the quality gets really bad.
I was guessing that the indicator on the left is the indicator which separates digital zoom from the sensor-zoom.
As far as I thought the light grey indicator-bar shows the part which is the sensor zoom and the dark part is the digital zoom.
Considering the quality it seems to me that both modes are digital zoom. The picture looks really annoying while i use it.
I just thought maybe I'm doing something wrong - has anyone an idea how I can improve this or use it right or or or...
Regards,
Matthias
I didn't know about the 8mp restriction, i also tested it out in the shop, but in 20mp mode. The sections looked identical. However, as the sensor is not at it's limits at 8mp, i guess it could take a higher resolution and crop it to 8mp size at the zoomed in section.
Auto mode enables you to use the camera's Clear Zoom feature, which produces good-looking, lossless-like digital zoom.

the image is stretched by the software, which then attempts to fill in the blanks as best as it can. Well, thanks to the giant sensors on the Nokia Lumia 1020 and Sony Xperia Z1/Z1 Compact, zoom is no longer a problem. But instead of opting for bulky zoom lens (Galaxy S4 Zoom), they both rely on their massive resolution in order to get what we call 'lossless' zoom.
So what's lossless zoom, then? In simple terms, it means that zooming into a scene will only result in a negligible loss in quality. Think of it this way: there are so many pixels available with a camera like the one on the 1020 that you can 'crop' any part of the photo and still have more than enough pixels for a full-sized photo that will appear zoomed in. No upscaling, and no loss of quality. But how does it work in practice?

So conclusion is, it is all digital zoom

Okay, it is something like digital zoom. But I think, the quality while zooming into an 8mpix picture should not be worse in quality (depending on the zoom factor) than the 20mpix picture.
When I take a 8 mpix picture, I assume that the image processor will take it in 20mpix and shrink it down to 8.
And what I would like to see is that
I could zoom in and it will just move into the sensor to a 1:1 size.
Another thing : while using the video mode, the stabilizer does an amazing job.
What about the photo-mode? I can't see any stabilisation there.
Since I only take 8mpi pictures, I guess the picture-frame could also be panned around the 20m of the sensor...

In SA mode, phone take oversampled photo (which means he take 21mp, but he make HD pixel (one pixel combine colors from neibghours)... so when you take 8mpx it takes 20mp ovesampled.
When you zoom in, it will take more and more neibhours pixel to combine in one, so that means loseless.
I've been honor 8 since one week and i have found one thing that when even i cover right side lens it capture black image but when ever i cover left side sensor it's take snappy sharp image like it's ideally take . So i think so it's just fake second camera is dummy or any other problem ? please let me know i'm worried for my money
Are the pictures good? If so then don't worry about it.

From my experience the second camera is mostly used for background blur effect. If you cover the lens, everything is in focus.
It is also used for minor noise reduction. If you take a picture in low light and cover the secondary lens there is a little bit more noise. But you won't really notice it unless you enlarge the image.
well the fact that when you block one lens, the other works is proof that neither is dummy. perhaps the post processing is not that dramatic as you were expecting. try taking low light pics with both and just the normal lens then compare them by zooming.
no difference found
I've tried in low light too but second lens is just a fake . it's don't enhances quality i think so i have to wait for android N update

I love the pictures the Honor 8 takes when using the Wide Aperture mode. It seems the second camera is essential for creating the blur effect. If you haven't noticed you can go into the Stock Huawei Gallery and adjust the wide aperture pictures after the fact. Even if you took a picture that looked like you focused in on the wrong thing, just go into the Gallery, click on the wide aperture button (only shows up on wide aperture pictures) and select what you wanted to focus on.
Sure enough, without the second camera the wide aperture mode doesn't work properly if at all.
Second lens is for focusing, depth of field, and additional light. As well, when covering the second lens, it persistently gives a warning about not covering the lens while shooting, especially when refocusing. I think this should be enough to disprove your "fake camera" theory.
This question is especially for the S8+ and upcoming S9 or new iphone. The sensor on the telephoto lens is always much smaller and quality much worse than the main lens so far.
Also, any luck on whether S9 will support 4k60p at h265?
Any comments?
Well, when you zoom in, you lose some quality by "cropping" the incoming light. Resolution is dependant on sensor, but if you zoom in you are taking a smaller portion of the scene that you see, if you get my point. It's not that tey don't want to, it's just physically much harder to make a zoom camera the same quality as a wide angle camera on such a small form as a smartphone camera.
Enthusiast cameras can have variable focal length lenses, they have complex lens combination that are physically adjustable (so called tele photo), when you 'zoom' there's no loss of resolution.
All cameras on mobile phones are to my knowledge fixed focal length lenses, the only zoom is digital which as Ertogrul implies reduces resolution.
Digital zoom is very much the poor relation in terms of image quality, but then we get what we pay for and a good tele photo camera lens will typically cost considerably more than any high end phone will cost.

Hi everyone!
Which resolution do you use, 12 mpx or 20 mpx? 12mpx gives you hybrid zoom x2 but phone only uses rgb lens, while 20mpx supposedly uses both lenses to create a hybrid colour/b&w pic. So which do you use? I have it on 12mpx in order to use zoom but don't really know which is best.
Cheers!
It actually depends on your preference and the situation you want to create in the photo. I use the 20mp when shooting wide angle landscapes, while im using the 12mp when shooting portraits or closeups

Thanks for replying! I've actually found that shooting a normal close up pic on 12mpx shoots in kind of a wide-angle effect. Last friday celebrating carnival at school, I was able to fit in a whole class of 28 kids from a few feet away. If u look at the pic, it looks like it has been shot on a wide-angle lens!
Any more opinions on camera config are more than welcome!
I don't believe that the 20MPx option uses both cameras. When you partially cover the B&W sensor, there is no noticable effect on the photo. Looks like it is only software based up-scaling and may get you jagged edges sometimes. After some testing with 20MPx and then 20MPx resized to 12MPx just for comparison, I prefer the 12MPx default setting.

Hi Marian, thanks for your reply!
So on a phone with a dual camera, what would be the purpose of the dual lens?? If one is rgb and the other monocrome, don't they both work together to provide depth information and zoom? Or do all colour pics use just the one rgb lens and the other is exclusively for b&w pics?? Seems a little pointless to me...
You are totally right about the sw upscale to 20mp as any other camera app only detects a maximum resolution of 12 mp, but it seems strange to me that even on 12mp colour pictutes, the phone wouldn't use both lens (depth and zoom) because the inferior P20 Lite precisely doess that on all the reviews I read about it (I've always thought that was the point of all dual-lens cameras).
Cheers!
The B&W sensor should provide depth information. You can try different camera modes and cover the B&W sensor. The phone says "Please do not cover the lenses." in some camera modes. But if you don't put finger too close, nothing happens. I can't tell it does anything at all to the image quality which seems strange. Did they made some mistake in latest build? It only does have some effect on aperture mode when you can see heat haze effect on display. It sucks we don't have more options like jpg quality or sliders for post-process filters.
Any one able to compare the camera with the Samsung S10? Is it better or worse?
Having both phones, I can say it's worse.
The main issue really is the exposure and whatever HDR+ algorithm they're implementing in the stock camera app. Even though they said it's the same HRD algorithm that was applied by google for pixel phones, I still think it's over exposing everything especially the low tones and shadows - this produce a very unnatural looking picture. (If I wear a black shirt, my pic came out as if I'm wearing a gray shirt due to overexposure on the shadows).
On the other hand, I'm really loving the flip camera and the ability to use wide angle for selfie/group selfie and video. That is definitely the highlight of this hardware. But I will be lying if I say I'm not struggling to love the quality of the pictures produced by this phone.
Have you tried the GCAM port? for me it produces better pics...
The Asus stock camera is hit or miss. Too inconsistent for me, especially the HDR++ mode.
But with arnova's GCam port it is simply amazing and blows away even the pixel 3 cameras.
The wide angle camera in our Asus does not focus as good as the main camera ..try it..also the slow motion videos are not that sharp and crisp.

Agreed, that there is sometimes overexposure, but I like more Asus camera's bright photos instead of GCAM darker photos. GCAM is better in very dark, but I prefer Asus camera often, specially for low light photos. Well, I have exposure compensation + 0,4 in GCAM, but still ...
I can easy say that this is the best cellphone camera on the market now, I installed Gcam and activaed raw.
I have never seen a phonecamera produce such a good raw files, even in low light.
Skintones, natural colors is great on this camera, Samsung, Sony, Huawei. and lot of other manufactors are terrible when it comes to natural skintones, overuse of noisce reduction....
Also the 4K 60fps is very natural and doesn't have the unatural look that almost every other brand have.
