About formats

SR2 is an early proprietary RAW image format used by Sony for select digital camera models, most notably the Cyber-shot DSC-R1 released in 2005 — a unique fixed-lens camera featuring a large APS-C CMOS sensor that was Sony's first to use this sensor size in a compact body. SR2 files capture the unprocessed 12-bit readout from the camera's sensor in its native Bayer mosaic pattern, preserving the full dynamic range and color information before any demosaicing, white balance adjustment, or tonal processing. The format uses a TIFF-based container structure with Sony-specific metadata tags and lossless compression to keep file sizes manageable while maintaining bit-perfect sensor data preservation. SR2 represents a transitional format in Sony's imaging history: it succeeded the earlier SRF format and preceded the ARW format that would become Sony's standard RAW format across the Alpha mirrorless and DSLR lineup from 2006 onward. The DSC-R1's APS-C sensor paired with a fixed Carl Zeiss Vario-Sonnar zoom lens made it an unusual proposition — essentially a compact camera with DSLR-class image quality — and SR2 files from this camera are valued by collectors. One advantage is the preservation of data from a unique camera design: the DSC-R1's combination of large sensor and fixed optics produced a distinct imaging character, and SR2 files retain the full RAW flexibility to explore this character with modern processing tools. SR2 files are supported by Adobe Lightroom, Adobe Camera Raw, dcraw, LibRaw, and RawTherapee.

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.
