What Is and ORF File and How Is It Used in Photography and Image Editing?

The acronym ORF stands for ‘Olympus RAW file’ and is Olympus’ proprietary version of a RAW photographic file. As such an ORF file contains only uncompressed or lossless photographic data with no editing. ORF files are what are captured on a compatible Olympus camera when a photographer wants to capture the highest levels of photographic information for manipulation in post-processing. ORF files are compatible with Olympus’ own image editing software and major editing suites such as Photoshop using the ORF plug-in. Due to the amount of information contained within an ORF file they are often large in file size.
