OP Stock Cam 48mp mode cropped aspect ratio - OnePlus 8 Pro Questions & Answers

Hi everybody
This bothers me a while: When I switch from 12mp to 48mp in camera mode to do a 'wider' picture, the camera only uses a part of the screen although "full" aspect ratio is selected. In 12mp mode the whole screen is used for the camera. Am I the only one?
Thanks for your answer and explanaition (I don't have one).
BR

you have it backwards. the "full" ratio is actually cropped in order to fit the phone's screen. the 4:3 ratio has the full resolution and captures more of the image.

4:3 or 16:9?

Hi guys
Noticed that on the 6p, the pixel were much lower if u choose 16:9
Which do u perfer to shoot with? 4:3 with more pixel, or 16:9 with less pixel?
and why you do it?
Thanks.
I prefer the 16:9 just because it fills the entire screen. It would be nice if we could have it both ways though.

but the 16:9 has a lesser pixel? do u notice the picture in 16:9 have a lesser quality compare to 4:3?
I also like that the 16:9 fill the entire screen, but the quality to me is important too

I've been using both off and on. To me the difference is minimal. The 4:3 seems to be a little better in low light but in bright light I can't tell the difference. I've been using open camera app to shoot 16:9 and google camera to shoot 4:3. I haven't settled on one or the other as my main shooter yet though. I'm debating on trying pro camera to see how it does. It won't be the first couple of dollars I've wasted if it isn't any better. I'm trying to find a good one that will shoot stills while taking video. I got used to that coming from my note 3 and then G4.

I'm in the same boat. While I enjoy 16:9 mostly, I prefer to get as much quality to my pictures as possible with the 4:3 before any processing. That said - ProShot looks pretty nice, but unfortunately it's reported changing EV has been disabled? What a dumb move by Google...

the full screen disply on 16:9 is one of the main reason i choose to use it. It just kinda weird to have black space on the side.....
i havent try any other camera software.. any recommendation u have?

I've tried several that are in the play store. For me open camera works the best out of the free ones. Search for open camera in the play store and give it a try. It had way more options than the google camera app.
Camera sensors are generally 4:3, even professional ones most the time are.
16:9 crops the sensor, hence lower megapixelsis

ALWAYS use 4:3 because only this way you will get all the pixels. You can resize it later and cut it down to whatever ratio you want - but you can never do it the other way round (without losing quality).
Yeah, the 4:3 vs 16:9 thing has been on my mind lately too... I like 16:9 pictures better, but when I compare the pictures I take, the only difference I notice is the 16:9 is basically zoomed in. You get no "wider" view, it just basically crops the top and bottom of the image off. There is a camera app or two that I've used that does make it wider, but those don't seem quite as nice as an image.

Well the aspect ratio of the sensor is 4:3, so it cuts of pixels until you get 16:9. Changing the aspect ratio without interpolation is only possible by cropping. Interpolation is what happens in the apps you mention which leads to decreased quality.

You don't get lesser quality when shooting in 16:9, it's the exact same quality. The only difference is the image is cropped at the top and bottom to achieve the 16:9 aspect ratio.
What's weird is the S6, Note5, and G4 have the full resolution at 16:9, where the 4:3 was a cropped version of 16:9.
I shoot in 4:3 to have the full 12.2MP image. I can always crop it later.

i do noticed that too
So to clarify, 4:3 has a wider angle and 16:9 is zoomed in right?
i just like the feeling that 16:9 takes up ur whole screen when viewing on photo app

so like other user are saying, is good to take it as 4:3 since u can edit later on but u cant edit when u shoot on 16:9 right?

Use any picture editor that features a "crop" function and remove part of the top and bottom of the original 4:3 picture until you get a 16:9 ratio or any other ratio you like (e.g. 3:2 is also common). Done.
It's the same as taking the shot in 16:9 but this way you can decide later which parts of the 4:3 you want to cut off (only top, only bottom or part of both).

Well you technically could edit a 16:9 image down to a 4:3 ratio by cropping the sides off the image. Doing this will result in an image containing even less pixels though. If you're really worried about it just take photos in the 4:3 ratio and crop them to 16:9 if you need to. I just have mine set to 16:9 all the time, I don't like the look of images in the 4:3 ratio. Using 16:9 allows the images to fill the screen on my phone, my tv, and my laptop (mostly).

yea, the only reason i will consider taking in 16:9 is that it fills the entire 6p screen

Video recording zooming.

Coming from a note 5, going from photo to video shooting, the aspect looked the same through the lens.
On the S7 edge screen I switch from photo to video it looks like it's zoomed in 2x. Can't someone with more knowledge than me explain why that is?
I guess that you have set photo mode to 4:3 ratio but video is 16:9 ratio so when you switch from 4:3 to 16:9 the top and buttom part is cropped/cut off and looked zoomed in since the camera sensor is a 4:3 rectangle.

Camera resolution question

aside from the obvious (less megapixels, and aspect ratio) are there any other "quality" related differences between the 21MP and 16MP setting in the camera?....
i prefer the 16:9 ratio of the 16MP setting for the wider angle shots, but are there any other downsides other than the megapixel differences?
Off the top of my head, file size?
IMO, after 8MP it's hard to truly notice a difference. I don't even know if the lenses can truly process the light effectively to get a true 16 or 21 mp picture.

Found something "funny" on rear camera max resolutions

front camera ok
2592x1458 16:9
2592x1944 4:3
but rear camera its where it get weird
5984x3366 16:9
5520x4140 4:3
on front camera you don't lose width when change to 16:9
but on rear camera you lose width,so they could add 5984*4140 even if it will be 1.36 Ratio

No they can't add 5984*4140. This image explains.

They can't
The IMX300 which we have on our Z5 devices are Multi Aspect sensors.
In real our device have 25MP Cam's inside but due multi aspect Sony branded it to 23MP which is what a multi aspect sensor with a size of 25MP uses. That's easier for Sony because they don't have to explain why their 25MP cam can just take 23MP pics

Camera Aspect Ratios and MP

Why is 16:9 Ratio locked to 12MP? When the main camera is 16MP, 4:3 Aspect Ratio can go up to 16MP, so why can't 16:9? And could somebody possibly develop a mod to allow 16:9 to take full capability of the camera, I would try but I don't know how to, just a question I thought I'd ask, thanks in advance for replies

16:9 just isn't a thing for 16MP. On any camera really. I'd try to explain it but I'm bad at explaining so I'll try to summarize (or at least how I like to think of it, someone can correct me). Think of megapixel as a large portion of a photo. When you have 12 it's basically 4 megapixels across and 3 megapixels tall, making 12. 16 just adds 4 more to the top or bottom row of the photo. So it's not a limitation of the phone, just of cameras in general.

The 16:9 (12MP) Toggle comes enabled on the phone out of the box (at least I think it does) (and if not, the stock rom I'm using, the Creator might have switched it, but it's not mentioned anywhere else in his thread) and 4:3 (16MP) won't let a picture fill the screen completely, I know MP isn't everything when it comes to a camera, but it's just odd that it's a 16MP main sensor with it only using 12 of 16 out of the box, it's possible I'm not comprehending this and all the last phones I've had (GS6 and LG G5) Both have had camera mods that's gave them 60FPS recordings, improvements in general, and 100% JPG Quality, I appreciate your answer, and as I've said I might be just not grasping it or not understanding the reasoning behind it, just was digging around the stock camera app came upon the setting and thought I'd ask people that know more about this stuff then me. Thank you.
It's a hardware sensor limitation in the 16mp camera for the LG V20, and while you could get an app on the market that takes 16:9 pictures on the v20 by stretching the 4:3 picture to fit the ratio, I would just accept what we have ATM considering the alternative is kinda harmful to image fidelity
EDIT: Yes there is an option to switch to 16:9 with the drop to 12mp/6-mp depending on the options you choose obviously (just looked thanks to the post Joe199799 made just before mine)
This "degradation" in Megapixel count is actually fairly normal and happens in most cameras. My previous phone had a 13MP camera but recorded 9.7MP 16:9 shots. Here's a detailed explanation for why this happens:
If you think about how a camera works, light passes through the lens to hit the sensor. Making this lens round is the easiest option to make the image projected onto the sensor as close to reality without any distortion. Making the lens another shape would distort the image, ab bit like using the wide angle camera does, which is difficult to correct in post.
The lens projects a circular image, which you want to record as much of as possible. A circular sensor could capture everything, but circular content on rectangular screens doesn't make much sense.
The next shape that takes up the most area within a circle is a square. But at the time digital image sensors were developed, computer screens had adopted ratios of 4:3 or 3:2, slight deviations from the square.
As a result, image sensors were also built in 4:3 ratios, which sacrifice some, but not too much of the entire projected image. Now, with screen ratios favouring more width, we could adapt our sensors, however, to capture images of comparable quality, lenses would have to become larger or sensor electronics would need to shrink. Neither option is particularly preferable, which is why the 4:3 ratio has stuck around and most cameras recording 16:9 images simply crop out part of a 4:3 image. Because it arguably makes sense, megapixel count refers to the entire area of the image sensor. By cropping the image, the megapixel count will obviously decrease as a certain amount of pixels is deleted.
