Taking Photographs-Image Quality and Size Compression ratio Image Quality and Size Making Effective Use of Memory Together, image quality and size determine how much space each photograph occupies on the memory card. Image Quality The D70 supports the following image quality options (listed in descending order by image quality and file size): Option Format Description NEF (Raw) (RAW) Raw 12-bit data from CCD are saved directly to memory NEF card in compressed Nikon Electronic Image Format (NEF). JPEG Fine (FINE) Fine image quality, suitable for enlargements Low or high-quality prints. (1 : 4) JPEG Normal Normal image quality, suited to most ap- Medium (NORM) JPEG plications. (1 : 8) JPEG Basic (BASIC) Basic image quality, suitable to distribution High by e-mail or use in web pages. (1 : 16) NEF+JPEG Basic (RAW BASIC) Two images are recorded, one NEF (RAW) image and one NEF+ basic-quality JPEG image. Image size ( 43) automatically JPEG set to L; JPEG image is 3,008 × 2,000 pixels in size. NEF (Raw)/NEF+JPEG NEF images can only be viewed using the software provided with the camera or Nikon Capture 4 version 4.1 or later ( 191). When photographs taken at NEF + JPEG Basic are viewed on the camera, only the JPEG image will be displayed. When photographs taken at NEF + JPEG Basic are deleted, both NEF and JPEG images will be deleted. File Names Photographs are stored as image files with names of the form "DSC_nnnn.xxx," where nnnn is a four-digit number between 0001 and 9999 assigned automatically in ascending order by the camera, and xxx is one of the following three letter extensions: "NEF" for NEF images, "JPG" for JPEG images, and "NDF" for Dust Off ref photos ( 166). The NEF and JPEG files recorded at a setting of NEF + JPEG Basic have the same file names but different extensions. Images recorded at an Optimize image > Color mode setting of II (Adobe RGB) have names that begin with an underbar, e.g., "_DSC0001.JPG" ( 56). 41
