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.

PS is the standard extension for files written in PostScript, the page description language created by Adobe Systems and first shipped in 1984 with the Apple LaserWriter. A PostScript file is a complete program that describes the precise appearance of a page — text, vector graphics, curves, fills, and even embedded raster images — using a stack-based interpreted language with full programming constructs. When sent to a PostScript-compatible printer or interpreter (such as Ghostscript), the program executes and produces rendered output. PostScript introduced cubic Bezier curves as the standard representation for smooth outlines, a mathematical model that became the foundation for virtually all subsequent vector graphics and font technology including PDF, SVG, and OpenType. The language also serves as a font format: Type 1 PostScript fonts encode glyph outlines as PostScript programs with hinting instructions for sharp rendering at low resolutions, while Type 3 fonts use the full language to define arbitrarily complex glyphs. One advantage is device independence — a PostScript file produces identical output whether rendered on a 300 dpi desktop printer, a high-resolution imagesetter, or a software rasterizer, because it describes shapes mathematically rather than as pixel grids. The human-readable text format provides another practical strength: PS files can be inspected, debugged, and modified with any text editor, and they can be generated programmatically by any software without requiring specialized libraries. PostScript files are widely handled by Ghostscript, Adobe Acrobat, preview applications, and numerous publishing and graphics tools.
