About formats

3FR is the proprietary RAW image format used by Hasselblad medium-format digital cameras, introduced in 2005 with the H2D camera system. The format captures unprocessed sensor data from Hasselblad's large CCD and CMOS sensors, which range from 39 to over 100 megapixels in modern bodies, preserving the full dynamic range and color depth recorded by the hardware. 3FR files store 16-bit-per-channel data alongside extensive EXIF metadata including lens correction profiles, white balance readings, and GPS coordinates when available. The files are substantially larger than consumer RAW formats due to the medium-format sensor area — a single 100-megapixel capture can exceed 150 MB — but this size reflects the extraordinary detail captured. One advantage is unmatched tonal resolution: the combination of Hasselblad's sensor technology and 16-bit RAW capture yields images with exceptionally smooth gradients and outstanding highlight/shadow recovery latitude, making 3FR the format of choice for high-end fashion, landscape, and fine art photography. Another strength is color fidelity — Hasselblad's Natural Color Solution (HNCS) technology, embedded in 3FR metadata, provides an ICC profile tuned to each specific camera unit, delivering color accuracy that approaches laboratory reference standards. 3FR files can be processed in Hasselblad's own Phocus software, Adobe Lightroom, Capture One, and other major RAW converters that support the format.

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.
