About formats

MEF is the proprietary RAW image format used by Mamiya medium-format digital cameras, introduced with the Mamiya ZD in 2004 and continued through subsequent models including the DM series. MEF files capture the unprocessed output from Mamiya's large-area CCD sensors — typically 48x36mm or larger — at 16 bits per channel, preserving the full dynamic range and color depth of the medium-format sensor before any demosaicing, white balance, or tonal processing takes place. The format uses a TIFF-based container that stores the raw Bayer-pattern data alongside embedded JPEG previews and extensive EXIF metadata including Mamiya lens identification, shutter speed, aperture, and metering information. Mamiya (later reorganized as Mamiya Digital Imaging and eventually merged into Phase One's operations) has a legacy stretching back to 1940 in medium-format film photography, and the MEF format represents the digital continuation of that tradition. One advantage is the medium-format sensor's inherent imaging qualities: the larger sensor area captures more light per pixel, producing lower noise floors, smoother tonal gradations, and a shallower depth-of-field rendering that medium-format photographers value for portrait, fashion, and landscape work. RAW flexibility is another practical strength — MEF files processed in Adobe Lightroom, Capture One, or dcraw allow photographers to apply modern demosaicing and noise reduction algorithms to these sensors, often extracting noticeably better results than the camera's original processing offered.

DOCX is the default document format for Microsoft Word since Office 2007, based on the Office Open XML (OOXML) standard published as ECMA-376 and adopted as ISO/IEC 29500. A DOCX file is a ZIP archive containing XML documents that describe the document body (document.xml), styles, themes, headers, footers, footnotes, comments, numbering definitions, and relationships between parts. Media assets like images and embedded objects reside in dedicated directories within the package. The XML structure means document content is human-inspectable and programmable — developers can create, modify, and extract content from DOCX files using standard XML libraries in any programming language without requiring Word. One significant advantage is openness and interoperability: the published specification enables any software to implement DOCX support, and the format is read and written by LibreOffice, Google Docs, Apple Pages, and dozens of other tools across all platforms. Built-in ZIP compression is another practical strength — DOCX files are substantially smaller than equivalent DOC files, and the modular XML structure improves crash recovery since corruption in one part does not necessarily destroy the entire document. The format supports all modern Word capabilities including SmartArt, content controls, bibliography management, accessibility metadata, and real-time co-authoring. DOCX has become the universal standard for document interchange in business, education, and government.
