About this format
SRF format context
Format: SRF
Overview
SRF matters historically because it belongs to Sony's earlier raw-file lineage, which still appears in older camera archives and compatibility conversion work.
Photography workflows needed a way to preserve sensor data and capture metadata before white balance, sharpening, tonal rendering, or lossy compression choices became permanent.
SRF is now primarily a legacy Sony raw compatibility target in migration and archive workflows.
SRF is closely associated with Sony.
SRF is usually selected for workflows that center on capture ingest, editing, web or print delivery.
Typical Workflows
- capture ingest
- editing
- web or print delivery
Common Software
- vendor photo software
- Adobe Camera Raw
- LibRaw-based workflows
Strengths
- Preserve capture-stage sensor information.
- Support deeper photo-editing and archival workflows than flattened delivery images.
- Retain metadata and workflow latitude that rendered outputs usually discard.
Limitations
- Compatibility often depends on vendor or decoder support.
- They are source formats, not publication-ready outputs.
- Public technical documentation is uneven across manufacturers.
Related Formats

Interesting Context
Before ARW became the better-known Sony raw family, Sony's raw ecosystem already included older variants that modern tools still need to decode correctly.
SRF belongs to legacy Sony digital-camera archives and raw software that retains backward compatibility with discontinued camera formats.
Its ecosystem is primarily archival and migration-focused.
Status: proprietary. Introduced: 2003. Invented by: Sony. Stewarded by: Sony.
How SRF fits into workflows
Workflow role: SRF
Convert to SRF when preserving older Sony originals or keeping a legacy Sony raw library intact.
