File category
Description
People, especially Nikon branded camera users, utilize this format in raw images. These files have lense-related metadata. These data are necessary for capturing images, setting details, etc. The format has an array of data as a record. Sensors of the camera through the lens obtain the record. The tones, colors, sharpness of the photo are editable without hampering the content. This feature isn’t properly applicable to compressed images. 12-bit images and 14-bit images have support from this format.
Technical details
You don’t need to modify the raw or initial file to alter NEF files. In cases of in-camera tasks like adjustment of tone, white balancing, sharpness, hue, it’s not necessary to apply to the NEF format permanently. These things remain as an instruction set in the file. Also, this file is editable without hampering contents. As compared to TIFF or JPEG files, NEF files’ color variety is wider. You can retain data of 12 and 14 bits using these files. You can view the image quickly, because these files have a version of the JPEG file and a thumbnail, apart from metadata. You can save or edit NEF files as NEF format or also as TIFF or JPEG formats. Editing, storing, printing, sending processes of these files are simple.
