About SRF
SRF (Sony RAW Format) is Sony's original RAW image format from their pioneering Cyber-shot digital cameras of 2003-2005. SRF stores unprocessed 12-bit sensor data from early CCD sensors, preserving the original image quality before in-camera JPEG processing. This format predates both SR2 (SLT cameras) and ARW (Alpha mirrorless).

SRF was used by notable Cyber-shot cameras including the DSC-F828 (8MP with unique 4-color RGBE filter), DSC-V3 (7MP compact), and DSC-R1 (the first fixed-lens camera with an APS-C sensor). These cameras were pioneers in bringing RAW capability to prosumer and enthusiast photographers before interchangeable-lens systems became dominant.
PNG (Portable Network Graphics) provides lossless compression with full alpha channel transparency, making it the go-to format for graphics, screenshots, and images requiring pixel-perfect fidelity. Created in 1996 as a patent-free GIF alternative, PNG uses DEFLATE compression and supports both indexed color (PNG-8) and truecolor with alpha (PNG-24/32). Files are 3-10× larger than equivalent JPEGs but preserve every pixel exactly.

PNG is universally supported and ideal for logos, UI elements, diagrams, and any content where transparency or lossless editing matters. For photographic content without transparency needs, JPEG typically offers better compression efficiency.

What is an SRF file?
SRF (Sony RAW Format) is Sony's original RAW image format from their early Cyber-shot cameras (2003-2005). SRF stores unprocessed sensor data directly from the camera's CCD sensor.
The DSC-F828 featured an 8MP sensor with a unique 4-color RGBE filter, while the DSC-R1 was the first fixed-lens camera with an APS-C sensor.
SRF files preserve maximum image quality from these innovative cameras that helped establish Sony in the digital photography market.
Why choose PNG over JPG?
What settings are used for the conversion?
Conversion settings:
- White balance: Preserved from your camera's as-shot settings
- Exposure: Auto-brightness applied for optimal results
- Color space: sRGB with standard gamma curve for accurate web display
- PNG format: 24-bit RGB lossless compression
- Metadata: Stripped for privacy (no GPS, camera info, or shooting settings)
Can I edit SRF files in Lightroom or Photoshop?
Partially. Adobe Lightroom Classic and Photoshop have limited SRF support. You may need to update Camera Raw profiles or use older software versions.
Better alternatives: Sony Imaging Edge Desktop (free), Darktable (open source), RawTherapee (open source with good legacy format support)
Converting to PNG is useful for archival purposes or when you need to access these vintage files in modern software without compatibility issues.
