Image Quality And Size: Making Effective Use Of Memory - Nikon D100 Manual

Image Quality and Size
Together, image quality and size determine how much space each photo-
graph occupies on the memory card. This in turn determines the total num-
ber of photographs that can be stored. For an understanding of how the
various size and quality options affect the number of images that can be
stored, view the following table, which shows the approximate number of
images that can be stored on a 96 MB card at different combinations of qual-
ity and size.
NEF (Raw) (uncompressed)

* All figures are approximate.
† Approximate time needed to record all images once the memory buffer has filled.
Actual time required varies with make of card.
** When opened in Nikon View 5 or Nikon Capture 3, NEF images are 3,008
pixels in size.
†† File size of compressed NEF (RAW) images is approximately fifty to sixty percent of
uncompressed NEF images.
*** Number of exposures remaining shown in control and viewfinder is the same as in
the case of uncompressed NEF (RAW) images. The actual number of images that
can be stored on the memory card is higher than shown.
