About formats

CR2 (Canon RAW version 2) is Canon's second-generation proprietary RAW image format, introduced in 2004 with the EOS-1D Mark II and used across Canon's DSLR lineup until the transition to CR3 beginning in 2018. CR2 files use a TIFF-based container that stores the raw sensor data compressed with a lossless variant of JPEG encoding (Huffman-coded prediction residuals), keeping file sizes manageable while preserving every bit of the original capture. Each CR2 file contains multiple image sections: a small thumbnail, a mid-size preview JPEG suitable for quick review, and the full-resolution RAW data at 14-bit depth on most bodies. The format records extensive shooting metadata including Canon's proprietary tags for lens model, autofocus point selection, Picture Style settings, dust-delete data from the sensor cleaning reference shot, and per-body calibration information. One advantage is the vast software ecosystem — CR2 is one of the most widely supported RAW formats in existence, handled natively by Adobe Lightroom, Capture One, DxO, RawTherapee, darktable, and dozens of other converters and viewers, owing to Canon's dominant market share during the DSLR era. Reliable archival longevity is another key strength: the TIFF-based structure and well-documented layout make CR2 files relatively straightforward to parse even with custom tools, and the format's ubiquity means archival support will persist for decades.
Developer: Canon
Initial release: 2004
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.
