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.
Developer: Epson
Initial release: 2004
MTV is a simple raster image format created by Mark T. VandeWettering for the MTV Ray Tracer, a ray tracing program released in 1988 as one of the early publicly available ray tracers distributed through Usenet. The format stores 24-bit RGB images with a minimal text header followed by raw pixel data. The header consists of a single line containing the image width and height as ASCII integers, followed immediately by the pixel data where each pixel occupies three bytes (red, green, blue) arranged in row-major order from top-left to bottom-right. The MTV Ray Tracer itself was significant in the history of computer graphics — distributed freely via the comp.graphics Usenet newsgroup, it introduced many programmers and students to the principles of ray tracing: ray-object intersection, reflection, refraction, shadows, and recursive shading. The MTV format was the program's native output, and its simplicity made it easy for users to write custom viewers and converters on whatever platform they had access to — a practical necessity in the fragmented Unix workstation landscape of the late 1980s. One advantage is extreme implementation simplicity: the format can be read in a handful of lines of code in any programming language, with no libraries, no compression algorithms, and no metadata parsing required — just read two integers and then read width x height x 3 bytes of pixel data. The format's historical significance in the computer graphics community provides another dimension — MTV files from early ray tracing experiments represent primary artifacts from the era when ray tracing transitioned from academic research to accessible software. MTV files are supported by ImageMagick and various legacy graphics tools.
