Comments

Nikon digital cameras use this format for storing Raw images.

By default, ImageGear automatically reconstructs colors in raw images during loading. You can disable one or more stages in the automatic color reconstruction, and reconstruct the images programmatically by using ImageGear Processing API. Use filter control parameters to disable specific stages of color reconstruction.

Nikon Raw files are compliant with TIFF/EP standard, and include EXIF metadata. They store a small color preview in the root IFD. An application that does not support NEF can read the root IFD as a regular TIFF image. Raw data is stored in a SubIFD, uncompressed or using huffman compression.
