Image Quality And Size - Nikon D5100 User Manual

Image Quality and Size

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.
