This is a format that is used to store RAW photos on Sony digital cameras without the use of compression. It contains the complete set of information that was captured by the camera's sensors through the lens when shooting with minimum adjustments. The opportunities for post-editing depend on the camera model and lens. ARW files can be created and edited in the ArtStudio Image software.
This format is used as the color palette format for a variety of operating system image editors. It is used to store font templates in text and graphic editors. It allows you to change color intensity and transparency levels.
