About formats

NEF (Nikon Electronic Format) is Nikon's proprietary RAW image format, introduced in 1999 with the Nikon D1 — one of the first professional digital SLR cameras affordable enough to see widespread newsroom adoption. NEF files capture the complete unprocessed output from Nikon's CCD and CMOS sensors at 12 or 14 bits per channel, using a TIFF-based container that stores the raw Bayer or quad-Bayer mosaic data alongside embedded JPEG previews at multiple resolutions, comprehensive EXIF metadata, and Nikon's proprietary MakerNote tags. The format supports three compression modes: uncompressed (largest files, no data alteration), lossless compressed (reduced size with bit-perfect reconstruction), and lossy compressed (further size reduction with a custom tone curve that compresses tonal values non-linearly). NEF's MakerNote data is particularly extensive, encoding the active AF point, VR (Vibration Reduction) status, Picture Control settings, Active D-Lighting parameters, and detailed lens correction data for Nikon's F-mount and Z-mount optics. One advantage is the enormous ecosystem of compatible software: NEF is among the most widely supported RAW formats worldwide, handled by Adobe Lightroom, Capture One, DxO, Nikon's own NX Studio, and virtually every RAW-capable application, reflecting Nikon's position as one of the two dominant professional camera brands through the entire digital photography era. The format's 14-bit capture mode provides another key strength — modern Nikon sensors deliver class-leading dynamic range, and the NEF file preserves this range fully, enabling dramatic exposure corrections in post-processing.

SXW is the word processing document format used by StarOffice 6.0 and OpenOffice.org 1.0, developed by Sun Microsystems and released in 2002. The format was one of the first mainstream office document formats to adopt an XML-based architecture, packaging document content, styles, metadata, and embedded media in a ZIP archive — a structural approach that directly influenced the later OpenDocument Format (ODF). The content.xml file describes the document body using XML elements for paragraphs, headings, lists, tables, footnotes, and inline formatting, while styles.xml defines the styling rules and meta.xml carries document properties. SXW represented a significant milestone in open-source office software, demonstrating that a non-proprietary XML format could handle the full range of word processing features including change tracking, indexes, cross-references, and complex page layouts. One advantage was transparency and openness — the XML structure made document content inspectable, transformable, and processable using standard tools, a sharp contrast to the opaque binary formats dominant at the time. The format's role as a technological precursor to the ODF standard is another historical significance: the OASIS OpenDocument Technical Committee used the OpenOffice.org XML format (including SXW) as the starting point for developing ODF 1.0. While SXW was superseded by ODT with OpenOffice.org 2.0 in 2005, existing SXW documents can be opened by LibreOffice, Apache OpenOffice, and document conversion tools.
