How Night Mode Helps Phone Cameras in Low Light

A phone can produce a surprisingly bright photo in a scene that looks very dark to your eyes. The result can seem as if the camera simply turned up the brightness, but modern night modes usually do much more than that. In low light, the camera has a basic problem: it receives fewer photons, the individual packets of light that an image sensor measures. With less light to work with, useful image information becomes harder to separate from noise. Night mode gives the camera more information and more time to build the final picture.
