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.

TIFF (Tagged Image File Format) is a flexible raster image format originally developed by Aldus Corporation (later acquired by Adobe) in October 1986 for desktop publishing and scanning applications. The format uses a tagged data structure where the image file header points to one or more Image File Directories (IFDs), each containing a set of tags that describe the image's dimensions, color space, compression, resolution, and other properties. This extensible architecture means TIFF can accommodate virtually any image type: 1-bit bilevel, grayscale, indexed color, RGB, CMYK, CIE L*a*b*, and beyond, at any bit depth from 1 to 64 bits per sample. TIFF supports multiple compression methods including none (uncompressed), LZW, DEFLATE, JPEG, and CCITT Group 3/4 fax compression, as well as multi-page documents, tiled storage for efficient random access to large images, and floating-point pixel values for HDR content. One advantage is professional-grade flexibility — TIFF handles the full range of image types encountered in publishing, prepress, medical imaging, geospatial analysis, and scientific research, where specialized color spaces and high bit depths are required. Lossless archival quality is another core strength: TIFF with no compression or LZW/DEFLATE preserves every pixel value exactly, making it the standard archival format for libraries, museums, and any institution that requires guaranteed long-term image fidelity. TIFF is supported by every major image editing, scanning, and publishing application across all platforms.
