Why are 13MP photos smaller than 9MP photos? - Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot

Just noticed this as my setting was on 9MP the whole time bc I re-flashed MF9 deodexed -___- just noticed that 9MP pics take up the whole screen, but 13MP pics do not... why is this? Or is there something wrong with my camera?

13 MP is a 4x3 ratio picture while 9MP is 16x9 (wide screen) ratio.

^what he said. the S4 screen is a 16x9 ratio, therefore the 9M mode fills up the screen. The 13M mode doesn't cut off the top and bottom to fit the screen, in comparison to the 9M mode.

A 9mp photo is just a crop of the 13mp sensor. The 13mp photos are actually larger when displayed at full resolution; they just look smaller on the phone's screen because of the aspect ratio.

Thanks to all! Which do you guys use?

6mp or 13mp??

Which do you prefer and why?
I'm so torn between the two 13mp seems to catch a slightly more crisp picture than 6mp but 6mp is a wider shot which fills the s4 screen well when showing images to friends and also its bigger on a computer screen when uploading to facebook.
You can use 9.6MP, it's also 16:9 ratio

Exactly what I am using 9.6. Really nice, enough quality, and like the Thread implies, fills the screen, which makes a huge difference.

Hey everyone,
Im wondering if anyone can answer this question regarding the resolution that I take pictures at on my note.
First off I like to take pictures in landscape mode, Its the only way I take pictures and videos.
I have noticed that if i set it to full 13mp and take pictures in landscape my pictures have a black line down either side of the screen. Basically turning my landscape picture into a portrait one. If I drop the resolution down to to 9.6 if fills the screen.... I can see the 16:9 but I am wondering if I can take pictures at 16:9 at the full resolution?
Thanks for reading

You can't sadly enough since the lens is so small it's actually not built to do a fill frame shot when you do 16:9 on a low mp it's just a software trick and with full res end taking better photos anyways with that

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

Why does video mode of camera zoom in so much.

Just like the title says. How come if im in "picture mode" of the camera and then switch to "video" it zooms in. Not just a little but a lot. Its actually kinda annoying how what would normally be in the frame for a picture is cropped so much for video.
Video fov (field of view) differs. Some sensors utilize it by "zooming in" to offer clearer video, some have wide, not so great-looking video.
It's due to software stabilisation, thats how it works, it crops the image to smooth it out, turn it off and it'll go back to normal

Nope it still zooms in

No it still zooms in a bit but no where near as much with the stabilisation off. I just tested it
Videos shot in 16:9, but it's a 4:3 sensor, so it has to crop it.
Sent from my Nexus 6P using Tapatalk
italia010 is correct. Stabilization zooms in so the software has a "buffer" of pixels to try and stabilize the image. With stabilization off, you're just seeing the top and bottom of the image get cropped when going from photo to video recording because of the change in aspect ratio from 4:3 to 16:9.

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.
