Pictures taken with a digital camera are stored as image files.
The size of the
files, and with it the number of images that can be recorded on the memory
card, depends on the quality and size of the images.
Before shooting, choose
image quality and size according to how the picture will be used.
Image Quality
The camera stores images in one of three formats: NEF (RAW), TIFF (HI qual-
ity), or JPEG (EXTRA, FINE, NORMAL, or BASIC quality).

To reduce the amount of memory each shot occupies, JPEG images are compressed as
they are saved to the memory card.
Compression selectively reduces the quality of the
image; the more a picture is compressed, the more noticeable this loss of quality is likely
to be.
This column gives the approximate compression ratio for each setting.
