Digital cameras use their individual RAW image file formats. Nikon camera uses NEF (Nikon Electronic Format) file with extension .nef as RAW image file. This is the base storage format from where you are able to convert to different file formats like JPEG, TIFF etc. These files contain image information that includes image meta data i.e., cameras identification, its settings, type of lens used and other information. This file is written to the memory card in two ways i.e., either in an uncompressed or lossless compressed form. The NEF file does not use in-camera processing for white balance, tone, sharpening as other image file formats. Instead, these values are saved as instruction set. This instruction set can be changed, as many times you want without ever-disturbing original image’s RAW data. You should use conversion software like Nikon Software Suite, Nikon ViewNX, Nikon Capture NX2, Adobe Photoshop etc to change NEF file format to other file formats. One of the main advantage using Nikon camera is after shooting of RAW files, capture NX provides few added tools that allow you to perform edits on your RAW files and thereby you can maintain a level of quality that cannot be achieved when shooting in JPEG or TIFF formats.
Using Nikon cameras, you can shoot combination of RAW format and any one of the JPEG formats. Favorite photos taken from Nikon cameras are lost due to various reasons like improper eject of memory card, malware attack, accidental format of card etc. Suitable nef file recovery software should be selected in this situation to recover deleted or lost photos.
NEF files use compression type called as visually lossless for images. When compression is applied to the image, it reduces its original size by 40 to 55 percent where small amount of data is lost. This image loss does not affect image visually and cannot be seen by the user. NEF files are larger compared to JPEG files. Therefore, you can store less images compared with JPEG image storage. These NEF files can save 12- bit or 14- bit data depending upon the camera. This results in great tonal range than eight bit JPEG or TIFF file. All Nikon cameras have inbuilt pre-set white balance settings for direct sunlight, flash, cloudy and shade. Auto white balance is another option that can adjust the white balance using color temperature that is measured by image sensor. When you are viewing your images, you can press the protect key to prevent accidental deletion of important images.
Remo Recover (Windows) – Media edition is powerful retrieval software that helps to recover deleted or lost photos, music, video files from hard drive. This tool is able to recover audio and video files of all popular formats. This utility supports recovery of different RAW file formats like Nikon (NEF), Sony (SR2, SRF), OLYMPUS (ORF), MINOLTA (MRW) etc. This software provides an option to recover data in compressed format. You can preview recovered NEF files prior to restoration when you download demo version of the tool and evaluate recovery chances of the tool.
