About this format
ORF format context
Format: ORF
Overview
ORF matters because Olympus and later OM System cameras built a strong enthusiast and travel-photography user base that still depends on raw editing flexibility and archive compatibility.
Photography workflows needed a way to preserve sensor data and capture metadata before white balance, sharpening, tonal rendering, or lossy compression choices became permanent.
ORF remains an important raw family in OM/Olympus-oriented editing and archival photo workflows before conversion into mainstream outputs.
ORF is closely associated with Olympus / OM System.
ORF 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
ORF belongs to the long Olympus digital-camera story, especially in the Four Thirds and Micro Four Thirds eras where portability and serious editing often coexisted.
ORF belongs to Olympus camera capture, raw processors such as Lightroom and Capture One, and photographic archives that preserve Olympus originals before export.
It is most relevant in Olympus-oriented editing and archive workflows.
Status: proprietary. Introduced: 2003. Invented by: Olympus (now OM System). Stewarded by: Olympus / OM System.
How ORF fits into workflows
