About formats

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.

HEIF (High Efficiency Image File Format) is a container format for images and image sequences standardized by the Moving Picture Experts Group as ISO/IEC 23008-12, first published in 2015. HEIF is built on the ISO Base Media File Format (ISOBMFF, the same container used for MP4 video), providing a flexible structure that can hold single images, image collections, image sequences (like animations or bursts), and derived images with non-destructive editing operations. The container is codec-agnostic — while the most common implementation pairs HEIF with HEVC/H.265 compression (branded as HEIC by Apple), the standard also accommodates AV1 compression (creating the AVIF variant), H.266/VVC, and other future codecs. HEIF supports features that JPEG lacks: 10-bit and 12-bit color depth, wide color gamuts (Display P3, BT.2020), lossless compression, alpha transparency, depth maps, thumbnail images, and Exif/XMP metadata — all within a single file. Auxiliary image items can store computational photography data like depth maps, HDR gain maps, and semantic segmentation masks. One advantage is the format's future-proof architecture: by separating the container from the codec, HEIF can adopt newer, more efficient compression technologies without changing the file structure, metadata handling, or application-level APIs. The substantial compression improvement over JPEG is another core strength — HEVC-based HEIF typically achieves 40-50% file size reduction compared to JPEG at the same visual quality, beneficial for storage and bandwidth. HEIF is supported by Apple's ecosystem (iOS, macOS), Windows 10/11, Android 10+, GIMP, ImageMagick, and Adobe products.
