It is from a friend that I heard:
Cellphone cameras, due to their small sensor size, can have at most 11 stops of dynamic range
(I did not ask too much about where that came from or what source is supporting this. I also paraphrased a bit since I cannot remember the exact sentence he said).
The idea does conform to what people commonly say, i.e. larger sensor can have a bigger dynamic range, and also aligns with the experience that cellphone photos produce a lot of blown-out or pure black.
I have seen this post, and most answers under the question seem to agree that theoretically, a larger sensor would have a higher dynamic range. However, using the box and ball example in that post, I wonder what limits the number of balls that fall into the box. Is it because there can only be so much ball in an area (the density of balls falling), or is it because the box has a maximum volume (the size limit of the box).
Say, would it be possible to have a box extremely tall, so that despite the cross area being as small as that 256-ball-box, this tall new box can hold 2048 balls?
I guess another way to ask my question is: would it be possible to make small senors/pixels holding as much light as the bigger ones? Or are there any theortical/physical rules that limit the maximum dynamic range with a given size?
