Common questions about ORF

Why can't I open my Olympus ORF photos in my usual editor? ORF is a camera-specific RAW layout, and editors only read the brands their developers tested — converting to JPG or DNG opens the photos anywhere.

Can Windows open ORF raw files? ORF is Olympus raw and Windows shows it only with an installed codec. macOS handles many bodies through its raw support and mobile apps usually cannot open it, so a converted JPG is easier to share.
