This format is used by Olympus cameras to create RAW images. These files record data from the camera matrix that are used to generate the image. It contains raw data about contrast, saturation, color temperature, as well as metadata. The exposure and white balance can be changed in an ORF image while maintaining the level of detail and quality of the photo.
This is the display format associated with the broadcast of slow-scan television. This legacy format was used to transmit a static image given limited bandwidth through the use of specialized software.
