3FR to ELECTRONIC Publication conversion is the process of transforming Hasselblad 3FR raw image files into EPUB (ELECTRONIC Publication) files, packaging one or more images and associated metadata into a reflowable or fixed-layout e-book container. This conversion typically involves converting raw sensor data to standard image formats (JPEG/PNG), applying color and exposure adjustments, then embedding those images along with navigation and chapter structure into an EPUB file for reading on e-readers and apps.

EPUB files use the MIME type application/epub+zip and package HTML, CSS, and multimedia into a compressed container suitable for e-books. Codecs involved include image compression for 3FR files and HTML rendering for EPUB documents.
