About formats

ORF (Olympus RAW Format) is the proprietary RAW image format used by Olympus (now OM Digital Solutions) digital cameras, introduced in 2000 with the E-10 digital SLR and continuing through the entire Micro Four Thirds OM-D and PEN lineups. ORF files capture the unprocessed 12-bit or 14-bit readout from the camera's Four Thirds or Micro Four Thirds Live MOS or CCD sensor, preserving the complete Bayer-pattern mosaic data before any demosaicing, noise reduction, or color processing. The format uses an Olympus-specific container that stores the raw data with lossless compression alongside multiple embedded JPEG previews, extensive EXIF metadata, and Olympus MakerNote tags encoding Art Filter settings, in-body image stabilization parameters, face/eye detection results, and computational photography mode information. ORF has evolved across several generations of Olympus sensors, from the original 4-megapixel Four Thirds CCD to the 20+ megapixel stacked sensors in current OM System bodies, and the format has accommodated these changes while maintaining backward compatibility in processing software. One advantage is the Micro Four Thirds system's depth-of-field characteristics: ORF files from these smaller sensors deliver greater depth of field at equivalent apertures compared to full-frame, a genuine advantage for macro, landscape, and travel photography where sharpness throughout the frame matters. Wide processing support is another strength — ORF files are handled by Adobe Lightroom, Capture One, DxO, Olympus/OM Workspace, dcraw, and RawTherapee.

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.
