About formats

RAF (RAW Format) is the proprietary RAW image format used by Fujifilm digital cameras, introduced in 2000 with the FinePix S1 Pro and continuing through the entire X-series mirrorless lineup and GFX medium-format system. RAF files capture the unprocessed readout from Fujifilm's image sensors — notably the SuperCCD, EXR, and X-Trans sensor designs — at 12 or 14 bits per channel, preserving the complete tonal and color information before any in-camera processing. What makes RAF distinctive among RAW formats is Fujifilm's X-Trans color filter array: instead of the standard 2x2 Bayer RGGB pattern used by virtually all other manufacturers, X-Trans uses a 6x6 semi-random pattern that distributes color samples more organically, reducing moire and false color without requiring an optical low-pass filter. RAF files from X-Trans sensors require specialized demosaicing algorithms that differ from standard Bayer processing. The format stores extensive metadata including Fujifilm's Film Simulation mode selection (Provia, Velvia, Astia, Classic Chrome, Acros, and others inspired by their analog film stocks), grain effect settings, dynamic range mode, and lens correction data for Fujinon XF and XC optics. One advantage is the Film Simulation heritage — Fujifilm's decades of film emulsion expertise informs the color science embedded in RAF metadata, and photographers can switch between film-inspired renderings during post-processing without quality loss. RAF files are supported by Adobe Lightroom, Capture One, Fujifilm's own X RAW Studio, dcraw, RawTherapee, and other major RAW processors.
Developer: Fujifilm
Initial release: 2000
EPUB (Electronic Publication) is an open ebook standard originally developed by the International Digital Publishing Forum (IDPF) and now maintained by the W3C following the organizations' merger in 2017. The first version carrying the EPUB name was approved in October 2007 as a successor to the Open eBook Publication Structure (OEBPS). An EPUB file is essentially a ZIP archive containing XHTML or HTML5 content documents, CSS stylesheets, images, fonts, and metadata organized according to the Open Packaging Format and Open Container Format specifications. The current major version, EPUB 3, supports reflowable and fixed-layout content, embedded multimedia, JavaScript interactivity, MathML equations, and rich accessibility features including semantic markup and media overlays for synchronized text and audio. A defining advantage is universal device support — unlike proprietary formats, EPUB works natively on virtually every non-Kindle e-reader, tablet, and reading application, from Apple Books and Google Play Books to Kobo and dozens of third-party apps. The reflowable text model is another core strength, automatically adapting pagination, font size, and margins to match any screen dimension and user preference. EPUB's open specification and active W3C stewardship ensure long-term preservation and vendor independence, making it the de facto standard for digital publishing across libraries, academic institutions, and commercial retailers worldwide.
Initial release: October 2007
