Olympus RAW
The raw format for Micro Four Thirds photography.
ORF is the proprietary raw image format used by Olympus (now OM System) cameras. It is the standard raw format for the Micro Four Thirds system cameras produced by Olympus. ORF files contain the unprocessed data from the sensor. Because Micro Four Thirds sensors are smaller than APS-C or Full Frame, the raw data is critical for maximizing image quality, noise reduction, and dynamic range.
ORF files are TIFF-based. They store 12-bit or 14-bit sensor data. A unique feature of modern Olympus cameras is 'High Res Shot' mode, which shifts the sensor to take 8 or 16 images and merges them into a single massive raw file (up to 80 megapixels). This resulting file is still an .orf, but it contains vastly more data than a standard shot.
ORF has been used since the early Olympus E-System DSLRs. It has persisted through the transition to mirrorless PEN and OM-D series. With the rebranding to OM System, the format extension remains .orf.
AVIF (AV1 Image File Format)
The royalty-free successor to WebP, offering the world's best compression for the web.
AVIF is the cutting-edge image format derived from the AV1 video codec. Developed by the Alliance for Open Media (AOMedia)—a consortium including Google, Netflix, Amazon, and Microsoft—it was designed to be the ultimate royalty-free format for the web. AVIF offers significantly better compression than WebP, which was already better than JPEG. It supports features that WebP lacks, such as 10-bit and 12-bit color depth for HDR (High Dynamic Range) images, and it produces fewer compression artifacts at low bitrates. While encoding AVIF files takes longer than other formats, the bandwidth savings are substantial, often reducing file sizes by 50% compared to JPEG.
AVIF uses the HEIF (High Efficiency Image File Format) container structure but encodes the image data using the AV1 video codec. This allows it to use advanced video compression techniques like intra-frame prediction to squeeze image data down to incredibly small sizes. Unlike WebP, which is limited to 8-bit color, AVIF supports 10-bit and 12-bit color depths, making it the first viable web format for HDR photography. It also supports 4:2:0, 4:2:2, and 4:4:4 chroma subsampling, allowing for sharp text and graphics even with lossy compression.
The AV1 video codec was released in 2018 as a royalty-free alternative to HEVC (H.265). The AVIF image format specification followed in 2019. Adoption was rapid compared to previous formats. Chrome added support in 2020, followed by Firefox in 2021. Apple added support in iOS 16 and macOS Ventura (2022), completing the 'universal support' puzzle much faster than WebP did.
