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 for storing bitmap images. It supports many different file types and compression algorithms. One Palm bitmap file can contain multiple versions of the same images with different colors. These files are used on PALM devices.
