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.

FB2 (FictionBook) is an XML-based ebook format created by Dmitry Gribov in 2004, designed to provide a clean semantic description of a book's content independent of its visual presentation. Unlike page-layout formats, FB2 encodes structure — title, authors, chapters, annotations, genres, epigraphs, poems, footnotes, and binary attachments (typically cover images) — within a single well-formed XML document. This structural approach means reading applications have full control over rendering, allowing the same file to adapt perfectly to a small phone screen or a large e-ink reader. FB2 became enormously popular in Russia and Eastern Europe, serving as the dominant format on major Russian digital libraries and ebook distribution platforms. One significant advantage is metadata richness: the format's schema mandates detailed bibliographic information including author, translator, series position, publication date, and genre classification, making library management and discovery straightforward. The plain-text XML foundation is another strength — FB2 files are human-readable, easy to validate, and simple to transform using standard XML tools like XSLT. The format specification is freely available on GitHub, and a wide ecosystem of readers, editors, and converters supports it across all major platforms, from desktop applications like Calibre to dedicated e-readers with native FB2 rendering.
