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.

DOCM is a macro-enabled document format for Microsoft Word, introduced with Office 2007 as part of the Office Open XML family. Structurally identical to DOCX — a ZIP archive containing XML parts for document content, styles, themes, and media — DOCM adds the ability to store and execute VBA (Visual Basic for Applications) macro code within the document. The separate .docm extension was a deliberate security measure: users and administrators can distinguish macro-containing files by extension alone, and group policies can restrict macro-enabled formats while allowing standard DOCX documents to open freely. DOCM files store VBA projects in a vbaProject.bin stream within the ZIP package alongside the same XML document content used by DOCX. Macros in Word documents enable automated report generation, custom form processing, document assembly from templates and data sources, and integration with external systems. One advantage is document-level automation — a DOCM file can include routines that populate content from databases, enforce formatting rules, validate fields before submission, or generate derivative documents automatically. The format preserves full compatibility with the OOXML specification, so all standard Word features — styles, tracked changes, comments, embedded media — work identically to DOCX. DOCM is supported by Microsoft Word on Windows and macOS, with macro execution limited to the desktop application.
