- Description
- An NEF file is a raw photo captured by a Nikon digital camera. It is saved in an uncompressed format that stores data exactly as it was captured by the CCD. NEF files also contain image metadata, which includes the camera ID and the lens that was used.
- Group 4 (G4) used for black and white lossless compression to maintain high-quality images, commonly used in TIFF format compression by fax machines. A picture is seen as black dots and lines on a blank page; the fewer the dots and lines are, the lesser the file size.
