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.

MOBI is an ebook format originally developed by Mobipocket SA, a French company founded in 2000 that was later acquired by Amazon in 2005. The format builds on the PalmDOC/PDB container structure, adding support for HTML-based content markup, embedded images, a DRM layer, and a JavaScript subset for limited interactivity. MOBI files use a record-based database architecture inherited from Palm OS, with a header structure containing metadata like title, author, publisher, and language followed by compressed HTML content records. The format became the foundation of Amazon's early Kindle ecosystem — the original AZW format used on first-generation Kindles was essentially MOBI with Amazon's own DRM wrapper. MOBI supports reflowable text with basic formatting including bold, italic, headings, lists, and tables, as well as internal hyperlinks and a built-in table of contents. One advantage is broad device compatibility: MOBI files are recognized by Kindle devices and apps spanning over a decade of hardware, as well as numerous third-party readers on desktop and mobile platforms. The format's lightweight structure is another strength — even long novels produce compact files that load quickly on modest hardware. While Amazon has since moved to the more capable AZW3/KF8 format for new publishing, MOBI remains widely circulated in existing ebook libraries and continues to be produced by conversion tools like Calibre for maximum Kindle compatibility.
