About formats

ERF is the proprietary RAW image format used by Epson's digital rangefinder cameras, most notably the R-D1 released in 2004 — the world's first digital rangefinder camera — and its successors the R-D1s and R-D1x. ERF files capture the unprocessed 12-bit output from the camera's APS-C sized CCD sensor (a 6.1 megapixel Bayer-pattern chip), preserving the full dynamic range and color depth before demosaicing, white balance, or tone curve processing. The format uses a TIFF-based container structure with Epson-specific metadata tags that record shooting parameters, lens information (manually entered via the camera's aperture ring, since rangefinder lenses lack electronic contacts), and the camera's unique analog gauges display readings. The R-D1 series holds a special place in photographic history as the camera that brought digital capture to Leica M-mount rangefinder lenses, and ERF files from these cameras are prized by collectors and enthusiasts. One advantage is the unique rendering character: the combination of the CCD sensor's tonal response and the optical qualities of classic rangefinder lenses produces a distinctive look in ERF files that many photographers find closer to film than the output of CMOS-based cameras. Practical accessibility is another strength — despite the camera's rarity, ERF files are supported by Adobe Lightroom, Adobe Camera Raw, dcraw, RawTherapee, and other modern RAW processing software, ensuring these files remain fully usable with current tools.

OXPS (Open XPS) is a fixed-layout document format standardized as ECMA-388 in June 2009, representing an evolution of Microsoft's original XPS specification. The format packages fixed-layout pages, fonts, images, and metadata in a ZIP-based Open Packaging Conventions container — the same packaging framework used by DOCX, XLSX, and other Office Open XML formats. Each page is described using an XML markup language that specifies paths, glyphs, images, and canvas elements with precise coordinates, producing documents that render identically regardless of the viewing device or printer. OXPS incorporated several changes from the original XPS: the use of JPEG XR for high dynamic range images, support for the Open Packaging Conventions 2nd edition, and alignment with the Ecma standardization process. Windows 8 and later generate OXPS (rather than XPS) when printing to the Microsoft XPS Document Writer. One advantage is standards-based document fidelity — as an Ecma standard, OXPS provides a vendor-neutral, fully specified format for documents that must look identical everywhere they are rendered, essential for legal filings, regulatory submissions, and archival records. The fixed-layout model is another strength: unlike reflowable formats, OXPS documents preserve exact page composition including precise glyph positioning and vector graphics. Built-in support in Windows and the .NET framework provides native viewing and creation capabilities without third-party software.
