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?

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.
All the time i am taking pics with rare camera having 10mp resolution only.
And the pictures taken with front camera having 3.8mp resolution only.
Why? Is there any settings that i don't know, as i am taking pics in high quality mode.

Just change the camera frame from 16:9 to 4:3 standard
Its because of the camera frame 16:9 is wide that is why the 3.8mp but 5mp is squarish so 4:3
Ok now i got it.

Hi
How have you set your camera ? 12 or 20mb ?
Thx
20mp
12MP RGB

You can select 20 megapixel as the resolution for the rear cameras to shoot, it combines data from both cameras so you can shoot in color too at 20 MP. This can be changed however you like in the camera settings.
I know I searched the internet for this before I bought one because I wanted to be sure. Haha.
In low light better to use 12,cause at 20 mp the image get little bit blurry when mixing 2 images at low shutter speed.
Outdoor u wont be worry to use 20 all the time.
They set the default mp at 12 for a reason

I know, but if you use 20MP, you can not zoom.

A 12 mp sensor cannot shoot 20 mp images, that's impossible. The camera software can boost it to 20 mp though using info from the 20mp monochromatic sensor. Which gives a decent result I have to say!
I am no camera wiz, just a point to and shoot guy. Nor am I a photo conesour in terms of evaluating a good vs great photo. But, I can tell when a photo stinks. Mostly, I just want to set it and forget it and have the best all around chance at good, clear pics.
All that said, I set to 12 and 20 MP and damned if I can see a difference. And it is a very challenging light situation where I just tested (both, IMHO, show off the great camera in this phone). I am outside on patio near midnight, with only light being from a string of Christmas lights in background d an little ambient light from room inside and courtyard beyond the patio. Hard to tell any difference in these two pics. First is the 12 and second is the 20 .. HDR on for both, no zoom.
So what are the situations one would expect 12 to have advantage, same for 20, same for HDR verse flash?

At any rate, contrary to some of the reviews, I think the camera a great with good lightning conditions and pretty good in darker conditions.

A lot of the early reviews were with the pre-release software although some have updated their reviews to reflect that.
I still hear that the camera has trouble with movement in low-light photos causing blurriness. Can anyone confirm that?
I am a photographer and I'm very impressed with my mate 9 camera.
I have used lot of phones but this one is the best by far.
If ur not happy with the auto mode just put it to pro mode and enjoy.

Sure it can, it happens all the time. Let's say this were a conventional 12MP single sensor camera. Would you then be OK saying it can shoot 12MP images? Assuming it had a typical Bayer array color filter, that 12MP sensor really only has 6MP for green, 3MP for blue, and 3MP for red. It does not have 12m full color pixels. Yet that's what comes out of the camera, via interpolation. At least with the Mate 9, it can produce 20 MP of luminance data without interpolation. It's just the chroma data that is at a lower resolution and requires interpolation. But encoding images and videos with lower chroma resolution than luminance is extremely common, because our eyes have much less color resolving capability vs. b&w. See Chroma Subsampling.

Sure, that's basically what I said. This sensor is 12mp (rgb sensor can be boosted to 20mp through interpolation, using the info (captured data) from the 20mp monochromatic sensor. Great results.

The photos are fantastic! To the best of your recollection, would you please share the settings you used in each one. Thanks!
Thats rather hard, I use pro mode and just fool around with aperature, speed and the rest until I'm happy. In auto mode I always point the camera around the subject until I like the lighting and than touch the screen on the point where I want to focus. That's it basically...
Those pic's look professional! Kudos

Hello, I've been an XDA lurker for a while, starting with my Galaxy S4. I just recently got a OnePlus 6, and love it so far, but this one problem is kind of irritating me.
When using the front camera (both in the camera app when not set to 4:3, and third party apps like snapchat), the picture looks very zoomed in). I'm guessing its because any other ratio is just a cropped version of 4:3.
The only way I can think to fix this is to force a different ratio for the camera to use, but I'm not sure if that is even possible.
Anyone else have this type of problem? Help would be much appreciated.
I think its because the lense has a higher focal length... Nothing to do with ratio.
So is there any way to work around this so that the front image isn't so zoomed in?
For video? It's because of their stabilization

I mean in the pictures. Like if you're taking a selfie, the viewfinder shows the image as very zoomed in (like your face covers the image if you're a normal distance away), and the picture is taken like that.
When you shoot with 4:3 you have all the picture of the sensor. When you shoot with 16:9 or other you don't use all the sensor but it crops the image to be in that ratio. And you see the zoom. Take a picture with 4:3 and zoom with your fingers to see a picture of 16:9 shot. It's the same.

Ì sent my Samsung A70 back because 16:9 was limited to 8 MP, I knew little about aspect ratios their respective resolutions, now that I have read a lot about it I am somewhat wiser. I was used to taking 16:9 photos on my S8+ and cropping the picture to my liking while maintaining the 16:9 AR. This requires a somewhat larger original picture if you wish to view the result on a large screen.
I bought the 7 pro and immediately ran into the same problem, aspect ratios are stuck to a certain resolution and 48 MP is limited to 4:3 JPG format, I can´t even choose 16:9 and decided to go along with the 20:9 fullscreen option ... can still easily be cropped to 16:9. But why are aspect ratios locked into a certain resolution which is usually okay in it´s original size for viewing but doesn´t allow for a lot of creativity.
I have been using a Gcam mod which has 16:9 available and the pictures do allow for a small crop, not much though before the pixels suffer on the big screen.
I will never use 4:3 as I hate the field of view it offers.
4:3 is likely the native sensor size/ratio. It comes from mimicking film cameras. Film cameras in turn copied oil painting canvases. 16:9 is just a compromise television format to approach Cinema formats roughly 21:9.

Yes, I figured that. Why are the size of the pictures restricted in all aspect ratios? that´s my question. As the average consumer you get 48MP advertised when you buy the phone, large pictures are however impossible to shoot in any other aspect ratio than 4:3 and for that you need to tweak the settings. For most people the camera will be 12 MP at most.
Why can´t I f.ex. shoot a 16:9 picture at 24 MP? I realize the fact that it´s impossible to get a 48 MP picture at 16:9 due to how the camera angle works.
The main sensor has 48 million pixels laid out in a 4:3 aspect ratio. Furthermore they are grouped in a quad Bayer layout which really just makes it a 4x light sensitive 12mp camera instead of a 48mp detail sensor. That is the hardware.
If you want images cropped to another aspect ratio afterwards, download something like Open Camera or MX Camera and set a custom resolution.

All third party apps are limited to the 12 MP, they don´t know how to use the 4x .... so they are pretty limited in their range of resolutions.
Yes and regrettably can't use the other lenses either.

Cinema is 2.35:1 which is why on 16:9 shows you the black bars on the top and bottom of your screen for the majority of movies.

Unless your going to print MASSIVE size prints, overall, MP is a marketing ploy to get your to spend more money on am item. After 12 to 16mp, for 95% of people, the difference is in the pixel size in Montana, not the number is pixels.

So in general, when stock camera takes 12mp photo on 48mp sensor, it would be using pixel binning, resulting in better looking image, right?

If yes, then if 3rd party Apps can capture photos at 12mp only, is it using pixel binning on main 48mp sensor or some other tech? If other tech, what is that other tech?
Thanks!
Even non Bayer sensors use four sensors filtered for each color. Generally an RGGB configuration. One sensor with a red filter, two with green and one with blue. They aren't individually addressible. They are summed together in hardware to mix all the colors. A Bayer configuration of groups allows sub addressing of different luminance channels.

Thanks for more details. Also, if you could, please answer (maybe you already answered but I did not get it) the doubts I asked above.

It might be a custom API that only the manufacturer accesses with their binary or camera app. Google camera2 API may not support it but people do cool stuff with the Google camera app to get at stuff.
