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.
The G3 format is used to compress image files in TIFF format when sending faxes. The compression algorithm allows for the use of a standard 10-times compression, which can be increased. It is used to remove excess image data, which makes it possible to reduce the size of the image and speed up delivery.
