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.

TCR (Text Compression for Reader) is a compressed plain-text ebook format developed by Barry Childress in the early 1990s for the Psion Series 3 family of palmtop computers. The format was created for Childress's Reader3 application, a text file viewer that needed to fit large books into the Psion's extremely limited storage — typically 128 KB to 2 MB of available memory. TCR uses a dictionary-based compression scheme derived from the earlier ZVR format by Ian Giddings, replacing repeated byte sequences with single-byte tokens that reference a header dictionary. This straightforward approach achieves compression ratios of roughly 40-60% on typical English prose while requiring minimal CPU resources for decompression. The Psion Series 3 ran on a 3.84 MHz NEC V30 processor with no floating-point unit, so TCR's low computational overhead was essential for smooth page-by-page reading. A key advantage is remarkable storage efficiency for its simplicity — users could carry dozens of novels on removable SSD cards that held only a few hundred kilobytes. The format found a dedicated user community among Psion enthusiasts who built libraries of compressed literature for portable reading years before smartphones existed. Though the Psion platform faded from the market in the early 2000s, TCR files can still be opened and converted by modern ebook tools, and the format stands as an early example of purpose-built mobile reading technology from the pre-smartphone era.
