The Shooting MenuMenu Guide—The Shooting Menu136File Type and Compression: Image QualityThe Image Quality menu controls the file typeand compression ratio used as photographs aresaved to the memory card. The following optionsare available:OKImage QualityNEF (Raw)TIFF-RGBJPEG FineJPEG NormalJPEG BasicSHOOTING MENUOption DescriptionTIFF-RGB Images are saved in uncompressed TIFF RGB at a color depth of eightbits per channel (24-bit color).JPEG Fine Images are saved in JPEG format at a compression ratio of roughly1 :4.JPEG Normal Images are saved in JPEG format at a compression ratio of roughly1 : 8.JPEG Basic Images are saved in JPEG format at a compression ratio of roughly1 :16.NEF (Raw)Raw 12-bit data from the CCD are saved directly to the memorycard in Nikon Electronic Image Format (NEF). NEF files can only beviewed in Nikon View 5 or Nikon Capture 3 ( 169). Two NEFmodes are available:• NEF (Raw)In this mode, NEF images are not compressed, reducing the timeneeded to process images before they are saved to the memorycard but increasing file size.• Comp. NEF (Raw)In this mode, NEF images are compressed using a virtually “loss-less” algorithm that reduces file size by approximately fifty to sixtypercent without affecting image quality. More time is required toprocess images before they are saved to the memory card ( 43).For more information on:44 Image quality
