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.

PDB (Palm Database) is a generic database container format created by Palm, Inc. for the Palm OS platform, first appearing with the original PalmPilot in March 1996. In the ebook context, PDB files most commonly use the PalmDOC or Plucker encoding to store readable text with basic formatting. The format consists of a 78-byte header identifying the database name, creation date, and record count, followed by a record index table and the data records themselves. PalmDOC-encoded PDB files use a simple LZ77-based compression scheme to pack plain text efficiently, while Plucker extends this with HTML rendering, image support, and hyperlink navigation. PDB ebooks powered a thriving mobile reading ecosystem years before dedicated e-readers existed — millions of Palm OS users carried entire libraries on devices like the Palm V, Tungsten, and Treo handhelds. A primary advantage is extreme simplicity: the flat record structure and minimal overhead mean PDB files parse instantly even on severely constrained hardware with limited memory and processing power. The open, well-documented structure is another strength, having spawned numerous reader applications across Palm OS, Windows, and later mobile platforms. Though the Palm platform is long discontinued, PDB ebooks remain accessible through conversion tools and readers like Calibre, and the format holds historical significance as one of the earliest practical mobile ebook solutions.
