What happens to extra pixels of photos

[Naman Malik]

Most of the phones these days have 1080p pixels which is approx 2million pixels on screen but phones have so high megapixel cameras such as honor view 20 having a whooping 48 megapixels camera so What happens to all these extra pixels and how do more pixels contribute to better photos or do they even have a role in better photos.

the image the camera takes has no bearing on the screen you view it on

So what will be the practical advantage of higher pixels if screen can't bear them

for viewing on something that isn't a cell phone screen

for cropping a section you dont want without losing quality

for...... ugh....

for reference , we had a digital camera in 2001 that shot in 2560x1600 as its max resolution , now can you think of a reason why it might be good in 2018 to have high resolution pictures of the past vs low resolution ones despite the fact that the camera had a 240p screen on it?

High resolutions mean the analog image is better represented by digital pixels. Remember, light isn't limited to square pixels, so the more pixels you have, the more data is preserved. Those very high resolution images are then digitally downscaled for viewing on screens that may be only 1080p, which looks far better than viewing an image of a resolution that matches the screen.

Photos taken by camera are not meant to be shown on screen only. You can print the picture out, with much higher resolution than your screen.
