Type of files called ORF is graphical format invented by Olympus. In practice it is remake of RAW file format, which was modified by Olympus. They upgraded it and use it in their devices. Format ORF has low compression ratio, however it can take pictures in high quality. In fact it takes exactly everything what is entering camera lens. Main advantage of this file format is that he contains some kind of header, which saves data about picture, but it also saves technical information about camera, which was used to take certain picture.
