About formats

MRW is the proprietary RAW image format developed by Minolta (later Konica Minolta) for their digital SLR and advanced compact cameras, introduced in 2001 with the DiMAGE 7, one of the first consumer-grade digital cameras to offer RAW capture alongside JPEG. MRW files capture the unprocessed 12-bit readout from the camera's CCD sensor in its native Bayer mosaic pattern, storing the data in a container format with a series of tagged data blocks for the raw image, camera settings, and proprietary metadata. The format was used across Minolta's digital camera lineup including the DiMAGE A-series advanced compacts and the Dynax/Maxxum 5D and 7D digital SLRs — the latter being the first DSLRs with built-in sensor-shift image stabilization, a technology later inherited by Sony when they acquired Konica Minolta's camera division in 2006. MRW files preserve the original sensor values needed for high-quality demosaicing, custom white balance, and exposure adjustment, giving photographers flexibility unavailable with the camera's in-body JPEG processing. One advantage is historical technological significance: MRW files from the Dynax 7D and its predecessors document the pioneering implementation of in-body stabilization and other innovations that became industry standards, and the RAW data preserves these early captures in their most flexible form. Continued compatibility is another strength — MRW files are supported by Adobe Lightroom, dcraw, LibRaw, RawTherapee, and other modern RAW converters, keeping these Minolta-era digital negatives fully usable with current processing algorithms.

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.
