Convert RAF to FF

The RAF file extension stands for Fujifilm Raw Image File, a format used by Fujifilm digital cameras to store uncompressed image data directly from the camera's sensor. Introduced to preserve maximum image quality, RAF files contain minimally processed data, allowing for extensive post-processing flexibility. This format, based on the TIFF/EP standard, includes metadata such as camera settings and format version. RAF files are primarily utilized by professional photographers and enthusiasts for high-quality image editing and archiving.

The Farbfeld (FF) file extension stands for "Farbfeld Lossless Image", a format designed for simplicity and efficiency in parsing and piping image data. Introduced by the Suckless community, Farbfeld stores images in a straightforward, uncompressed format, making it ideal for use with external compression algorithms. This format uses 32-bit RGBA values for each pixel, ensuring lossless quality. Its history traces back to the need for a minimalistic, easily manageable image format that avoids the complexity of integrated compression found in formats like PNG.
