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.

WMF (Windows Metafile) is a vector graphics format created by Microsoft, introduced with Windows 3.0 in May 1990 as the platform's native format for recording and replaying graphical operations. A WMF file captures a sequence of GDI (Graphics Device Interface) drawing commands — lines, rectangles, ellipses, polygons, text, and bitmap blits — in the order they were issued, serializing screen or printer output into a replayable file. The format uses a 16-bit coordinate space and organizes records as a linear stream of function calls with their parameters, preceded by a header specifying the bounding rectangle and resolution. WMF became deeply integrated into the Windows ecosystem as the default format for clip art collections, Office document graphics, and clipboard vector interchange during the 1990s — Microsoft Office shipped with thousands of WMF clip art images that defined a visual era of desktop publishing. One advantage is pervasive compatibility: virtually every Windows application from the past three decades can render WMF content, making it one of the most widely supported vector formats in existence. The lightweight recording model is another strength — WMF files are compact and render quickly because they replay native system drawing calls rather than interpreting a complex graphics language. While 16-bit limitations and lack of transparency and Bezier curves led Microsoft to develop EMF as a 32-bit replacement, WMF files remain ubiquitous in legacy documents and across current Windows software.
