SR2 to DBK Converter

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.
