SR2 (Sony RAW 2) is Sony's earlier RAW format used by pre-Alpha digital cameras, including the groundbreaking Cyber-shot DSC-R1 — the first consumer camera with an APS-C sensor in a fixed-lens body — as well as the DSC-F828, DSC-V3, and some early Alpha models. SR2 files contain 8-10 megapixel Bayer sensor data from CCD and CMOS sensors. The format was eventually superseded by ARW (Alpha RAW) as Sony standardized on the Alpha brand.
Converting SR2 files to BMP produces uncompressed bitmap images from these pioneering Sony cameras. BMP's simplicity ensures universal readability on legacy systems, industrial equipment, and scientific instruments that cannot process modern image formats or proprietary RAW data.
BMP is universally readable by every operating system and basic image viewer. SR2 files from Sony's pre-Alpha era are supported by progressively fewer RAW processors as software vendors focus on current formats. Converting to BMP creates permanent, universally accessible copies of these historically significant photographs.
The Sony DSC-R1 was a landmark camera that influenced the later mirrorless revolution by proving APS-C sensors could work in compact form factors. Photographs from this camera and its contemporaries deserve preservation in a format that will remain readable indefinitely — BMP provides that guarantee.
The conversion reads the SR2 container, extracts the 8-10 MP CCD or CMOS Bayer sensor data, and performs demosaicing. Sony's embedded white balance, color matrix, and tonal curve metadata are applied during processing. The output is written as a 24-bit Windows DIB with bottom-up row ordering. The DSC-R1 (10.3 MP) produces a BMP of approximately 30 MB uncompressed. The DSC-F828 (8 MP) produces about 23 MB.
BMP applies zero compression — the format conversion is completely lossless. The pixel values exactly match the demosaicing output. Sony's CCD sensors from this era had distinctive color rendering — warm, saturated, with smooth tonal transitions — and BMP preserves this character faithfully. The primary quality consideration is the one-way demosaicing interpretation.
