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
SNB is a proprietary ebook format developed by Shanghai Nutshell Electronics, a subsidiary of Shanda Interactive Entertainment, for the Bambook e-reader launched in August 2010. The format is structurally based on EPUB principles, packaging HTML content, CSS styling, images, and metadata within a compressed archive, but uses a proprietary container that restricts native playback to Bambook devices and associated software. Shanda designed the Bambook and its SNB ecosystem as an integrated reading platform tied to the Cloudary literature portal (later rebranded as China Literature), one of China's largest online publishing networks hosting millions of web novels and serialized fiction. The format supported reflowable text, chapter navigation, bookmarks, and basic typographic controls suited to Chinese-language content display. One advantage was tight integration with Shanda's massive content catalog, providing readers instant access to an enormous library of Chinese-language literature directly through the device. The Bambook was initially offered at a heavily subsidized price point, using the content ecosystem to drive revenue — a model that preceded similar strategies by other e-reader manufacturers. While the Bambook hardware line was eventually discontinued as the Chinese market shifted toward tablet-based reading apps, SNB files from that era can be converted to standard formats using tools like Calibre with appropriate plugins. The format represents an interesting case study in platform-specific ebook ecosystems within the Chinese digital publishing landscape.
