Convert NEF to SIXEL

The NEF file extension stands for Nikon Electronic Format, a proprietary RAW image file format used by Nikon digital cameras. These files capture all image data as seen by the camera sensor, providing greater flexibility for post-processing and higher image quality compared to compressed formats. NEF files are essential for professional photographers and IT specialists in photo editing due to their uncompressed nature, allowing precise adjustments in color, exposure, and detail retention. Nikon introduced this format to enhance image fidelity and editing capabilities, maintaining a pivotal role in digital photography since its inception.

The SIXEL, or "six pixels", is a bitmap graphics format created by Digital Equipment Corporation (DEC) for their terminals and printers. Initially designed for DEC dot matrix printers like the LA50, it enabled the efficient transfer of bitmap graphics using a series of ASCII characters. Each character represents a 6-pixel high row, making it suitable for 7-bit serial communication. This format was later adapted for modern terminal emulators, extending its utility beyond its original scope.
