About formats

DNG (Digital Negative) is an open, royalty-free RAW image format published by Adobe Systems on September 27, 2004, designed to address the proliferation of incompatible proprietary RAW formats from different camera manufacturers. Based on the TIFF/EP standard (ISO 12234-2), DNG provides a well-documented container for raw sensor data with standardized metadata tags that describe the camera's color filter array pattern, color calibration matrices, default rendering parameters, and opcodes for geometric corrections. The format supports both original raw mosaic data and linear (demosaiced) DNG, as well as lossy DNG using JPEG compression for smaller archive sizes when full quality is not critical. Adobe has iterated the specification through multiple versions, adding support for transparency maps, floating-point HDR data, enhanced color profiles, and semantic masks in newer revisions. One advantage is archival reliability — DNG's published, non-proprietary specification eliminates the risk that a camera manufacturer's format becomes unreadable when that company exits the market or drops support for older models, a concern that motivated Adobe's creation of the format. The format also enables embedded original RAW data, letting users convert their CR2, NEF, or ARW files to DNG while optionally keeping the original bits inside the DNG for reversibility. Broad ecosystem support is another strength: Adobe Lightroom, Photoshop, and Camera Raw treat DNG as a first-class format, and many smartphone manufacturers (including Google and Apple for certain modes) output DNG natively.

Initial release: September 27, 2004
SIX is a file extension for SIXEL (Six Pixel) graphics data, a bitmap graphics format developed by Digital Equipment Corporation (DEC) in 1983 and introduced with the LA50 dot matrix printer. SIXEL encodes images as a sequence of printable ASCII characters, where each character represents a column of six vertical pixels (a 'sixel') — the character's ASCII value minus 63 provides a 6-bit binary pattern, with each bit controlling one pixel in the vertical column. The encoding is structured as a series of sixel bands (each six pixels tall) across the image width, with control sequences for color selection (up to 256 registers with HLS or RGB specification), repeat counts (run-length encoding for efficiency), carriage return, and newline commands. SIXEL data is transmitted to the output device using DEC's standard escape sequence protocol, embedded within the text stream alongside regular character output. Originally designed for DEC's line of printers and later supported by DEC VT-series terminals (VT240, VT330, VT340), SIXEL has experienced a remarkable revival in modern terminal emulator software. One advantage is terminal-native image display: SIXEL allows images to be rendered directly within a text terminal session without requiring a graphical window system, enabling command-line tools to display graphs, photographs, and previews inline with text output. This capability has driven adoption in modern terminals like mlterm, xterm, WezTerm, and foot. SIX/SIXEL data can be generated by ImageMagick, libsixel, and chafa, and viewed in any SIXEL-capable terminal emulator.
