Pictures taken with a digital camera are stored as image fi les.  The size of the 
fi les, 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).

pression, preserving high level of detail at fi le size 
slightly smaller than that of TIFF images.
HI 
2, 4
TIFF 
(RGB)
High image quality (on par with NEF) in format sup-
ported by most imaging applications.
EXTRA
JPEG
1 : 2
Produces best quality JPEG images; fi le size is small-
er than NEF or TIFF.
FINE
1 : 4
Fine image quality, suitable for enlargements or 
high-quality prints.
NORM
(NORMAL)
1 : 8
Normal image quality, suited to most applications.
BASIC
1 : 16
Basic image quality, suitable for pictures that will be 
distributed by e-mail or used in web pages.
1 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.
2 Available only in PSA, and M modes.  Selecting 
 (auto) or scene mode resets 
image quality to EXTRA.  Digital zoom (
