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.

AZW3, also known as Kindle Format 8 (KF8), is Amazon's advanced ebook format introduced in November 2011 alongside the first Kindle Fire tablet. It replaced the older MOBI-based AZW format with a substantially more capable layout engine built on HTML5 and CSS3 subsets, enabling fixed layouts, embedded fonts, SVG graphics, drop caps, and other typographic refinements that were impossible in earlier Kindle formats. Internally, an AZW3 file packages content in a structure derived from EPUB, wrapped in Amazon's proprietary Palm database container with optional DRM protection. The format supports both reflowable text for novels and fixed-layout pages for comics, cookbooks, and children's titles. One major advantage is rich formatting fidelity — publishers can produce visually sophisticated ebooks with complex page designs, nested tables, and precise font control that render consistently across the Kindle ecosystem. Another strength is backward compatibility: AZW3 files can bundle a MOBI fallback section so older Kindle hardware still displays the content, even without full KF8 rendering. The format integrates tightly with Amazon's Kindle platform, supporting features like X-Ray, Whispersync page tracking, and in-book dictionary lookups across millions of devices and apps worldwide.
