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.

PCX (PiCture eXchange) is a raster image format created by ZSoft Corporation in 1985 as the native format of their PC Paintbrush application, one of the first painting programs for IBM PC compatibles. The format uses a simple run-length encoding (RLE) compression scheme that works by replacing consecutive identical pixel values with a count-value pair, achieving modest compression on images with large areas of uniform color. A PCX file consists of a 128-byte header (specifying dimensions, color depth, palette information, DPI, and encoding method), the RLE-compressed pixel data organized in scan-line order, and an optional 256-color palette appended after the image data. The format evolved through several versions supporting increasing color depths: 1-bit monochrome, 4-bit (16 colors), 8-bit (256 colors), and 24-bit true color using multiple color planes. PCX became one of the most popular image formats during the DOS era, widely supported by paint programs, word processors, desktop publishers, and early games throughout the late 1980s and early 1990s. One advantage was broad DOS-era software compatibility — PCX served as a practical interchange format when competing programs used proprietary raster formats. The simplicity of RLE decoding is another strength, requiring minimal CPU and memory resources ideal for the hardware of that period. While PNG, JPEG, and other modern formats have replaced PCX in contemporary use, the format remains encountered in legacy archives and retro computing contexts.
