Digital SLR Camera Basics
This file extension for Nikon image files is an abbreviation of “Nikon Electronic Format”. RAW photographs taken with Nikon SLR cameras are stored in NEF format. Unlike JPEG and TIFF formats, in which repeated processing results in a progressive loss of image data and degradation of the image, NEF format stores the original image data separately from processing and retouch information, allowing images to be repeatedly processed and saved with no effect on the original image data.
A type of image artifact (mottling or graininess) visible in photographs taken at high ISO sensitivities or slow shutter speeds.
An abbreviation of “National Television Standards Committee,” NTSC is a video standard in use in North America, as well as in Japan and some other countries.
