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.

DjVu (pronounced "deja vu") is a document format developed at AT&T Labs by Yann LeCun, Leon Bottou, Patrick Haffner, and Paul Howard, first released in 1996. The format was specifically designed for storing scanned documents and images at very high compression ratios while maintaining visual quality suitable for on-screen reading. DjVu achieves this through a layered approach: the document image is separated into a foreground layer (text and line art at full resolution), a background layer (photographs and textures at reduced resolution), and a mask layer that determines which layer is visible at each pixel. This separation, combined with purpose-built compression algorithms for each layer type, typically produces files 5-10 times smaller than equivalent JPEG or PDF scans. One advantage is exceptional compression on scanned pages — a 300 DPI color scan that might occupy 25 MB as TIFF or 500 KB as JPEG typically compresses to 40-80 KB in DjVu while preserving legible text. The progressive rendering model is another strength: DjVu files stream efficiently over networks, displaying a readable low-resolution version almost immediately while progressively refining to full quality. The format supports multi-page documents, embedded text layers for searchability, hyperlinks, annotations, and a shared dictionary mechanism that further compresses collections of similar pages. DjVu is widely used by libraries and archives for digitized historical documents and manuscripts.
