16 is just a number. it doesn’t define the picture quality alone. there
are other factor which also responsible for a good photo.
each pixel has information if certain point in the picture. in the smart
phone there are lack of space so there are much number of pixels in a
small area but on the other hand in DSLR there are enough space for
enough size of pixels. larger the pixel size maps the larger area and
good quality information.
the aperture is the opening of the lense. larger aperture extracts more
light which results in brighter picture. aperture is a major factor of
quality of photos when it comes to low light photography. in this
situation the same pixel contains more information.
it’s major factor now days and only answer to why smartphone cameras are
competing with DSLR. you have collected a good amount of information
from your hardwere to produse a good quality picture but untill it
doesn’t go through a good image processing it can’t make the picture
quality good. google is leading in this field which softwere image
processing. now it’s produsing bettter picture with less information
only on the basis of image processing
