Nikon D3400 - Image Quality and Size; Image Quality

84 More on Photography
Together, image quality and size determine how much space
each photograph occupies on the memory card.
Larger, higher
quality images can be printed at larger sizes but also require
more memory, meaning that fewer such images can be stored
on the memory card (0 323).
