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 (0335).

Choose a file format and compression ratio (image quality).
Image quality can be set by pressing the X (T) button and rotating the main
command dial until the desired setting is displayed in the control panel.
