NEF (RAW) to SIXEL Converter

This is a format that is used for RAW images on Nikon cameras. It contains metadata about the lenses that were used to take the photo, capture settings, and other conditions. It provides a record of the data array obtained by the camera sensors through the lens. It allows you to edit the sharpness, colors, and tones with no loss to the content or quality of the image, which is something that cannot be done with compressed images. It supports 12- and 14-bit images.

SIXEL is a bitmap graphics format developed by DEC (Digital Equipment Corporation) to use on printers and terminals. Such image consists of six pixels high and one pixel wide represented as an escaped sequence. If you want to open a SIXEL file but do not have a DEC terminal, the only way is to convert it to another more common format.
