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.

LRF is the file format associated with Sony's BBeB (Broadband eBook) specification, jointly developed by Sony and Canon and introduced in 2004 with the Sony Librie EBR-1000EP — the world's first commercial E Ink e-reader. The format supports both reflowable text and fixed-layout page rendering, embedding fonts, images, vector graphics, and metadata within a compact binary container. LRF files use a block-based internal structure with object trees describing page layouts, text streams, image resources, and table of contents navigation. Sony's Reader devices and the companion desktop software (Sony Reader Library) served as the primary ecosystem for LRF content throughout the mid-2000s. A key advantage was its early adoption of high-quality font embedding and text rendering optimized specifically for E Ink displays, delivering a reading experience noticeably superior to many competing formats of the era. The format also supported bookmark synchronization, dictionary lookups, and annotations within the Sony Reader ecosystem. However, Sony officially discontinued BBeB/LRF support in 2010, migrating its Reader platform to the industry-standard EPUB format. Today LRF files are primarily encountered in personal ebook collections from that period and can be converted to modern formats using tools like Calibre. The format remains a historically significant milestone as the native format of the device category that launched the modern e-reader revolution.
