About formats

K25 is a RAW image format specific to the Kodak DC25 digital camera, released in 1996 as one of the earliest consumer-oriented digital cameras capable of storing unprocessed sensor data. The DC25 featured a 493x373 pixel CCD sensor (approximately 0.18 megapixels) and could store images on a removable CompactFlash card — a notable feature at the time when most consumer digital cameras used fixed internal memory. K25 files capture the raw Bayer-pattern sensor readout before demosaicing and color interpolation, preserving the original sensor values for later processing. Despite the extremely modest resolution by today's standards, K25 represents a historically significant moment in digital photography: the DC25 was among the first cameras to make digital capture accessible to ordinary consumers at a price point under $500, and these RAW files document the technical state of consumer imaging sensors in the mid-1990s. One advantage is historical preservation value — K25 files represent primary source material from the dawn of consumer digital photography, and the RAW data can be reprocessed with modern demosaicing algorithms like AHD or LMMSE that significantly outperform the basic interpolation available in 1996, extracting noticeably better detail and color from these early captures. Continued software support is another practical strength: despite the camera's age, K25 files can be opened by dcraw, Adobe Camera Raw, LibRaw, and other RAW processing tools, ensuring these early digital negatives remain accessible.

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.
