About formats

PEF (Pentax Electronic Format) is the proprietary RAW image format used by Pentax digital SLR and mirrorless cameras, introduced in 2003 with the *ist D — Pentax's first digital SLR — and continuing through the current K-mount and medium-format 645 lineup. PEF files capture the unprocessed 12-bit or 14-bit readout from the camera's CMOS sensor in its native Bayer mosaic pattern, stored in a TIFF-based container with Huffman-coded lossless compression. The format includes embedded JPEG previews at multiple sizes, comprehensive EXIF metadata, and Pentax-specific MakerNote tags that record Custom Image mode settings, Shake Reduction (SR) gyroscope data, lens identification from the K-mount electronic interface, and the camera's Auto Level correction parameters. Pentax cameras are notable for their weather-sealed construction and compatibility with the vast legacy of K-mount lenses dating back to 1975, and PEF files from these bodies can include manual lens metadata entered through the camera's menu system. One advantage is the preservation of Pentax's distinctive color rendering — the brand's Custom Image modes (Bright, Natural, Reversal Film, Bleach Bypass, etc.) are stored as metadata rather than applied to the raw data, allowing photographers to explore different rendering interpretations during post-processing while the original sensor capture remains untouched. The format's longevity is another strength: PEF files from every Pentax DSLR are supported by Adobe Lightroom, Capture One, dcraw, RawTherapee, Pentax's own Digital Camera Utility, and other modern RAW processors.
Developer: Pentax
Initial release: 2003
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.
