ORF to DOT Converter

ORF (Olympus RAW Format) is the proprietary RAW image format used by Olympus (now OM Digital Solutions) digital cameras, introduced in 2000 with the E-10 digital SLR and continuing through the entire Micro Four Thirds OM-D and PEN lineups. ORF files capture the unprocessed 12-bit or 14-bit readout from the camera's Four Thirds or Micro Four Thirds Live MOS or CCD sensor, preserving the complete Bayer-pattern mosaic data before any demosaicing, noise reduction, or color processing. The format uses an Olympus-specific container that stores the raw data with lossless compression alongside multiple embedded JPEG previews, extensive EXIF metadata, and Olympus MakerNote tags encoding Art Filter settings, in-body image stabilization parameters, face/eye detection results, and computational photography mode information. ORF has evolved across several generations of Olympus sensors, from the original 4-megapixel Four Thirds CCD to the 20+ megapixel stacked sensors in current OM System bodies, and the format has accommodated these changes while maintaining backward compatibility in processing software. One advantage is the Micro Four Thirds system's depth-of-field characteristics: ORF files from these smaller sensors deliver greater depth of field at equivalent apertures compared to full-frame, a genuine advantage for macro, landscape, and travel photography where sharpness throughout the frame matters. Wide processing support is another strength — ORF files are handled by Adobe Lightroom, Capture One, DxO, Olympus/OM Workspace, dcraw, and RawTherapee.
