Image Quality The camera supports the following image quality options (listed in descending order by image quality and file size): Option File type Description Raw 12-bit data from the image sensor are saved directly to the memory card. Choose for images that will be processed on a computer. JPEG NEF (RAW) NEF copies of NEF (RAW) images can be created using the NEF (RAW) processing option in the retouch menu (pg. 220) or software such as h JPEG fine ViewNX (supplied) or Capture NX 2 (available separately; pg. 240). Record JPEG images at a compression ratio of roughly 1 : 4 (fine image quality). JPEG normal (default) JPEG Record JPEG images at a compression ratio of roughly 1 : 8 (normal image quality). JPEG basic Record JPEG images at a compression ratio of roughly 1 : 16 (basic image quality). NEF (RAW) + Two images are recorded: one NEF (RAW) image and one fine-quality JPEG fine JPEG image. NEF (RAW) + NEF/ Two images are recorded: one NEF (RAW) image and one normal-quality JPEG normal JPEG JPEG image. NEF (RAW) + Two images are recorded: one NEF (RAW) image and one basic-quality JPEG basic JPEG image. Image quality can be set by pressing the X (QUAL) button and rotating the main command dial until the desired setting is displayed in the control panel. Image quality can also be adjusted from the shooting menu (pg. 165). X (QUAL) button Main command dial Control panel A NEF (RAW) Images Note that the option selected for image size does not affect the size of NEF (RAW) images. When opened in software such as Capture NX 2 (available separately) or ViewNX (supplied), NEF (RAW) images have the dimensions given for large (L-size) images. A NEF (RAW)/NEF+JPEG When photographs taken at NEF (RAW) + JPEG Fine, NEF (RAW) + JPEG Normal, or NEF (RAW) + JPEG Basic are viewed on the camera, only the JPEG image will be displayed. When photographs taken at these settings are deleted, both NEF and JPEG images will be deleted. White balance bracketing (pg. 191) is not available when an NEF (RAW) + JPEG option is selected for image quality. Selecting an NEF (RAW) + JPEG option cancels white balance bracketing. 62
