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.
Developer: Hasselblad
Initial release: 2005
EPUB (Electronic Publication) is an open ebook standard originally developed by the International Digital Publishing Forum (IDPF) and now maintained by the W3C following the organizations' merger in 2017. The first version carrying the EPUB name was approved in October 2007 as a successor to the Open eBook Publication Structure (OEBPS). An EPUB file is essentially a ZIP archive containing XHTML or HTML5 content documents, CSS stylesheets, images, fonts, and metadata organized according to the Open Packaging Format and Open Container Format specifications. The current major version, EPUB 3, supports reflowable and fixed-layout content, embedded multimedia, JavaScript interactivity, MathML equations, and rich accessibility features including semantic markup and media overlays for synchronized text and audio. A defining advantage is universal device support — unlike proprietary formats, EPUB works natively on virtually every non-Kindle e-reader, tablet, and reading application, from Apple Books and Google Play Books to Kobo and dozens of third-party apps. The reflowable text model is another core strength, automatically adapting pagination, font size, and margins to match any screen dimension and user preference. EPUB's open specification and active W3C stewardship ensure long-term preservation and vendor independence, making it the de facto standard for digital publishing across libraries, academic institutions, and commercial retailers worldwide.
