Image Mode

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).

		Compression
Option	Format	ratio1	Description
			Raw data from CCD are saved in Nikon Electronic
RAW2, 3	NEF		Image Format (NEF) without processing or com-
		Not	pression, preserving high level of detail at file size
		compressed	slightly smaller than that of TIFF images.
HI2, 4	TIFF		High image quality (on par with NEF) in format sup-
	(RGB)		ported by most imaging applications.
EXTRA		1 : 2	Produces best quality JPEG images; file size is small-
			er than NEF or TIFF.
FINE		1 : 4	Fine image quality, suitable for enlargements or
			high-quality prints.
	JPEG
NORM		1 : 8	Normal image quality, suited to most applications.
(NORMAL)
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 P, S, A, and M modes. Selecting (auto) or scene mode resets image quality to EXTRA. Digital zoom ( 18) not supported.
