ok the pixel6 has three cameras. the front camera is self explanatory. but the stock camera app is very lacking in into.
1. what is the picture spec of "medium" photo resolution vs "full"
2. why would i want to switch between the two back cameras and how do i do that?
3. there are 5 things on the back camera block, what are they in order from left to right?
4. what is .7 vs 1x vs 2x? is it optical zoom or digital zoom? and how do they get .7 zoom? shouldn't .7 be 1x and the others adapted .
and no googling for answers did not revel any info.
all anyone seems to want to talk about is the software picture tweaks not the hardware and how you can use it,
I can take pictures of squirrels (Tree rats) with the Google camera app.
And Opossums with the night vision.
Just add, I believe you need to have a Google account to access all of the cameras app features.
Imo, these questions are easily answered by most reviews. Here's a review that tells you a lot about the camera.
pixel 6 specs
1. Medium vs full is going to be the amount of compression used. I don't know why you wouldn't ever use full.
2. You have to switch between cameras if you want different zoom since they use fixed focal length lenses. One is .7x and the other is x1.
3. Left sensor is the 50MP (x1) sensor, next is the x7 sensor, next is the laser auto focus sensor, and then the flash and I believe a microphone is above the flash. Just use your finger to cover one of the cameras if you don't believe me.
4. The main camera is used for x1, that's a 50mp sensor that uses 4->1 binning so it produces 12.5MP images. The .7x is just uses a more zoomed out focal length than the main sensor (lower quality sensor too). x2 is digital zoom on the main x1 sensor.

And if you think that is Kool.
Try using an Endoscope camera with the P6.
It really worked well for me trying to see up inside the dash of a classic car. (86 Monte)

I first noticed that my optical x3 photos had a fair bit of digital noise to them.
I then tried pinching to change the zoom and I couldn't see any transition between the lenses when going from 2.9x to 3x. You should be able to clearly see the transition between 0.9x and 1x
After covering up all the lenses one by one with my finger and changing the zoom level, I can see that the x3 view (which should be using the bottom left lens, as you are looking at the back of the phone) is only blocked when I cover up the standard lens (top right)
Can anybody else verify this? Is this some strange intentional behaviour or a bug?
Confirmed on my device too as a bug when viewing the screen.
However, if I try taking a photo the camera switches to the 3rd sensor to actually take a photo.
Must be a new 'improved feature'.

IMHO I suppose it's so by design, to allow the user for a smooth zooming experience, and it can be considered a bug only as far as the correct lenses are not used to take the final picture.
I think it's to do with the minimum focus distance to be honest. If you're trying to focus on something far away it will switch but something close it will switch back.
I think, the camera changes at zoom 3x if there is enough light, otherwise it will use the main sensor. I tested this by holding the camera on TV and on my low board, the room was dark.
Hello devlopers and friends Ever since I brought poco f1 and installed gcam and other third party camera apps my front camera resolution drops to 5mp. Only official camera app is able to use 20 mp resolution.
I know there are many threads about pixel Bining and stuff but i don't agree with them. The main problem is at the end a 5Mp Image is 5Mp and 20 Mp is 20 mp.
But i think and request devlopers to please look to it.
## According to my theory As confirmed by Device info Harware app There are three camera sensors in poco F1 out of which the one with camera ID 0 is 13 the one with camera ID 1 is 20 and with camera ID 2 is is 5 megapixel.
"
13 Mp back camera primary Camera Id 0
5mp back camera primary camera Id2
20 mp front camera Id 1
"
According to my theory the five megapixel and the 20 megapixel camera are conflicting with each other and gcam is taking the values from 5 megapixel instead of 20 megapixel sensor. So I request that developers that they can try I and confirm if it is the case and if it is true please make a fix for it
thanks
On specs sheet, the front facing camera has 20mp but in gcam it says 5mp. Google Camera is using what they called "Pixel Binning" and it is a software implementation.
This process is the procedure of combining a cluster of pixels into a single pixel. As such, in 2x2 binning, an array of 4 pixels becomes a single larger pixel, reducing the overall number of pixels.
13mp back camera is the main camera shooter
5mp back camera is the depth sensor
20mp front camera is the secondary camera shooter
One good example is this

Thanks for replying
The question is that why gcam and other apps detect only 5mp sensor.
Lets agree gcam uses pixel Bining and stuff.
But why other apps detect and capture 5mp are they all using pixel Bining.
And why only Mi Camera can capture at full potential of the sensor. Is there a catch we all are ignoring.
Pixel Bining or not at the end when zoomed 5Mp image is storing lesser data .
And also imagine a 20mp full resolution shot with gcam cam make things go from OK to wow.

It doesn't really change anything. And it doesn't mean more resolution = more quality. It is a matter of fact of image processing. If you really compare MIUI Stock Camera and Google Camera, you will see the big difference from the two since that Stock Camera doesn't uses Pixel Binning algorithm

Pixel binning gives better shots in low lighting conditions only. No significant difference in well lit conditions. Thats why i want to capture with full resolution in Google camera because its awesome.
Also if pixel binning is so justified why don't we capture 3 mp photo with rear camera and say its better than 13mp because its not
Justified ( That 20 mp shot from miui cam is not good than gcam)
Not justified ( That it is due to only pixel binning . It is due to google computational algorithms.)
#pixelbinning is justified only in badly lit photos not everywhere
Agreed doesn't mean More resolution=more quality
But More resolution =More information per inch in captured shot ( in case of gcam it means awesome shot)
More resolution =More information per inch in captured shot ( in case of miui camera it means ok shot cause it does not uses multiple shots and algorithms to produce good shots)

Then use the stock camera if you really wanted the 20mp. Use gcam if you wanted better image processing.
This was explained a long time ago and it is really not a big issue or some conspiracy about the 20mp sensor
Yes it is a issue One plus devices had this issue Zen devices had issues similar in Auxiliary camera regarding resolutions on gcam. All those were fixed due to efforts of devlopers.But i think people just want to accept everything and not work it out. If some one can try to find a fix there will be a fix. But if everyone just accept the fate lie down nothing is gonna happen
Similar issue, i can't change photo camera resolution on miui 11.0.5.0.

Dude, you are suggesting your gcam is taking front selfies with rear 5MP sensor?
A 20MP image is only twice as big 5MP image. Not 4 times big.
Gcam 5MP selfie carries much more details than 20MP MiUi camera, day or night. Period. MiUi camera does a lot smoothening.

Or maybe gcam does lot's of sharpening to make them look "detailed" zoomed out? When zoomed in you can see tiny coloured squares.
Update I used Redmi note8 Pro and Redmi k20 pro with gcam They all produce 5 mp front and 12mp back irrespective of the sensor resolution. Maybe gcam only supports these resolution maximum.
Honestly i would love larger resolution support with gcam .
In k20pro gcam can take images in 48 MP resolution
In back But issue is in front it only takes with 5mp resolution and this 5MP resolution is useless when you zoom the image or see it laptop you can see amount of noise.This really need a fix .
Can i disable Pixel Bining
I think no devloper is interested in This.
I wish there were devs who would look at it but sad thing is no one really care
True story
Actually Gcam detects full one Megapixel when individual pixel size is more that 1.1 π size..
Poco f1 or other Xiaomi phone with 20mp sensor has individual pixel size of 0.8/0.9/1.0 π size.
But Gcam detect full 13mp in my Redmi note 5 AI because the sensor's pixel size is 1.12 π.
Thus even in my old device has a 13mp insane Gcam selfie.
Wondering how much storage space will one picture take for the Google Pixel 6 take with the new 50MP camera. My current Google XL 2 using a 12MP camera would take ~5MB/picture.
The sensor uses pixel binning, so the output image is 12,5 MP.
The binned picture file size is also worryingly low. I wish they gave us more.optiions to select and store higher quality images and video.
You can always save in raw + jpeg, though I'm not entirely sure if it processes the raw image
This main 50 megspixel camera is compressing the photo so much that having 50 mp is useless. Too much compression and still using their computational technology at 12 megapixels so we aren't really seeing what the difference a 50 megapixel camera would make. File sizes should be 25 mb or higher with a jpeg at 50 megapixels. Yes I'm a photographer

You are right. Apart from some improvement to noise levels and colour, the details are virtually the same as my pixel 4xl.
I think the only real benefit of the 50MP sensor is when you zoom (hopefully). So when you zoom in it no longer pixel bins and you're using a native 12MP section of the sensor before you get into digital-only zoom.

I haven't found that to be the case. There is a 2x zoom that doesn't look too bad (slightly oilpaint like) and a 4x that is the optical zoom on the telephoto sensor that's very good... Another issue is the camera automatically switches between the main sensor at 4x and the telephoto 4x sensor depending on focal distance so you can't use the 4x optical to take close shots.
So what's the point of a 50MP sensor binned to 12.5MP if it always does it? Why not use a native 12.5MP sensor and get even more light in, by avoiding the gaps between the pixels used in each 'bin'?

As above, better noise level and light input.
Definitely better pictures on the main and 4x sensor than the pixel 4 xl for sure.
I just wish we had a full size version and higher quality image export.
So using 4x small pixels in a bin is better than one big one the same size for noise/light (assuming the technologies are the same)?
Ok so that seems to be the case

Photos would be much better in well-lit situations using 50 megapixels. Pixel binning down to 12 megapixels would be fine in low light but it's not acceptable to me to do this in well-lit situations. They need an update for the camera to decide when the situation is lit well enough to use the 50 megapixels and to decide when it's not lit well enough and use the 12.5 megapixels as they are. Because regardless of what anyone thinks s 50 megapixel photo would have much more detail than what's being done now by binning every photo. Google has to make a decision to move forward with their camera and use it to its fullest potential in which they are not doing now.
If i want a photo with 50 mpx can i just use raw ? Or it still bins?

Still a 12mp image. The file size is larger however and there's more info from the sensor to play with.
RAW images will also not be compressed in a lossy way
Maybe some gcam ports will allow us to take photos in 50 mpx...
I invite you to my post here:
https://forum.xda-developers.com/t/samsung-isocell-gn1-sensor.4359031/#post-85911883
Its a quad Bayer subpixel layout. Because it groups four of the same color pixel together it only has 12.5 mp of color data. The 50 mp claim is marketing bs. Essentially it just upscales the 12.5 mp image using the extra luma data. The sensor is also too small for 50 mp to turn out well.
The main advantage is you can do an HDR photo with one exposure. Because there's four subpixels, you can have four different exposure values with one photo. Although I don't think Google is utilizing this.
A 50mp picture would be a total waste with the lenses in these phones. The "extra" detail that a 50mp could show would be offset by the poor quality lenses (I'm speaking in general terms here - not specifically about one phone or another). These tiny phone lenses can only produce so much sharpness, clarity and detail. In other words, eventually it's the lenses that are the limiting factor in the picture quality and putting in a sensor with such high resolution that it greatly exceeds the quality of the lens will not produce better images.
By binning the sensor pixels, you get the benefit of "larger pixels" (so more light absorption) without exceeding the quality limitations of the lenses.
So you can't under any circumstances get at the 50MP un-binned image. What's the benefit of starting with 50MP and pixel binning down to 12.5MP vs. just using a 12.5MP sensor to start with?
Is this just marketing, the 50MP sensor is available to Google, and they have no appetite for giving users more than 12.5MP images in reality?
i.e. Is there any benefit to always pixel-binning a 50MP image to 12.5MP vs using a native 12.5MP sensor to start with? Pixel binning makes sense when you can get to the higher resolution image when lighting conditions make sense to allow that, but Google don't support it.
It has to do with the size of the sensor and the amount of light that is read by each "pixel".
Is pixel binning still used when using digital zoom?

Yes I know. But I don't think there's any benefit of 5OMP binned to 12.5MP compared to a native 12.5MP sensor of the same overall size (with bigger pixels)

Computational photography. The more points of data the better the image (theoretically, but it seems to work out).
Binning for standard images allows higher resolution zoom.
It probably also has to do with Google choosing a sensor already in production.

Sure, but that assumes that there is such a sensor available where in reality, what you will be able to find will be 1/4 the size.

Yes it is. Try taking picture with 2x zoom but with option to save also the raw file enabled. Looking at the resolution of the raw file it is just crop from the 1x zoom which is upscaled to 12mp using digital zoom.
Yeah, it seems like the camera software isn't fully baked yet for the new GN1 sensor. Samsung says that the purpose of their "Tetracell" technology is to provide a compromise between larger pixels for low light sensitivity and smaller pixels for higher resolution. So if Google isn't going to use the higher resolution for anything, I don't get why they went with this sensor. It seems like this extra resolution would be perfect in combination with their super zoom algorithm.
Crossing my fingers that they release an updated camera app that better takes advantage of the capabilities of the main sensor. It's Google though, so getting bored or distracted and dropping the ball on promising technology is one of their favorite things to do.

No, I guess that there isn't a significant difference. Google ignores the 50 and 48 megapixel modes of the Pixel 6 Pro sensors and that's a missed opportunity. So, Google's "super resolution" zoom is actually an anti-resolution zoom.
I guess that they chose this sensor because no other 12 megapixel sensor of this size was available. For example, the Sony Xperia Pro-I uses about the same sensor area as the Pixel 6. But they haven't chosen a 70mm² sensor with 12 megapixels, they are using 70mm² (12 megapixels) from a 20 megapixel 115mm² sensor.
When I am in the selfie camera and i open the gallery preview on the bottom left or close the camera app i hear this click sound coming from the front facing selfie camera. Also when i look super closely after switching or closing the app, i can see the selfie camera move backwards kinda.
Im aware of the rear cameras having OIS so it moves around and makes some sound but this seems to be coming from the front facing camera. I never switched to the back cameras so they never activated.
Can you guys with the 23 ultra test this and see if you have it too, im not sure if its normal behavior.

Of course the camera has OIS... It's a flagship. It would be basically criminal for it NOT to have optical image stabilization. Also, the iPhone Pro Max series has had OIS since at least the 12 Pro Max (in fact Apple claimed it had dual optical image stabilization, meaning the telephoto had it as well). Not having OIS means blurry images in anything less than the utmost stable of hands when taking a photo and it's why I hated my OnePlus 9 and wished I bought the 9 Pro even though I didn't want the curved screen. Were you thinking of some other feature?
