About formats

PEF (Pentax Electronic Format) is the proprietary RAW image format used by Pentax digital SLR and mirrorless cameras, introduced in 2003 with the *ist D — Pentax's first digital SLR — and continuing through the current K-mount and medium-format 645 lineup. PEF files capture the unprocessed 12-bit or 14-bit readout from the camera's CMOS sensor in its native Bayer mosaic pattern, stored in a TIFF-based container with Huffman-coded lossless compression. The format includes embedded JPEG previews at multiple sizes, comprehensive EXIF metadata, and Pentax-specific MakerNote tags that record Custom Image mode settings, Shake Reduction (SR) gyroscope data, lens identification from the K-mount electronic interface, and the camera's Auto Level correction parameters. Pentax cameras are notable for their weather-sealed construction and compatibility with the vast legacy of K-mount lenses dating back to 1975, and PEF files from these bodies can include manual lens metadata entered through the camera's menu system. One advantage is the preservation of Pentax's distinctive color rendering — the brand's Custom Image modes (Bright, Natural, Reversal Film, Bleach Bypass, etc.) are stored as metadata rather than applied to the raw data, allowing photographers to explore different rendering interpretations during post-processing while the original sensor capture remains untouched. The format's longevity is another strength: PEF files from every Pentax DSLR are supported by Adobe Lightroom, Capture One, dcraw, RawTherapee, Pentax's own Digital Camera Utility, and other modern RAW processors.

DOC is the binary document format of Microsoft Word, the word processor first released in October 1983 for MS-DOS and later becoming the dominant document creation tool worldwide. The format stores documents as OLE2 compound document files — a binary container with multiple internal streams holding text content, formatting information, embedded objects, macros, and metadata. The text stream uses a complex system of formatting runs, section descriptors, paragraph and character property tables, and style definitions to represent arbitrarily complex document layouts including columns, headers, footnotes, tables, floating images, tracked changes, and mail merge fields. The format evolved substantially through Word versions, with Word 97 establishing the binary structure that remained standard through Word 2003 and created the .doc files most commonly encountered today. One advantage is near-universal compatibility — DOC files can be opened by virtually every word processor and document viewer across all platforms, from Microsoft Office to LibreOffice, Google Docs, and Apple Pages. The format's rich feature support is another strength: DOC handles complex layouts, embedded OLE objects, VBA macros, and revision tracking that power enterprise document workflows. Although Microsoft introduced the XML-based DOCX format with Office 2007, DOC remains heavily present in existing document archives and continues to be produced by organizations maintaining compatibility with older Word installations.
