| Description | The Sony Alpha RAW image format is used by Sony digital cameras to store images, and captures the raw, uncompressed data for images as captured by the camera's sensors. Sony entered the photo market with its first camera in 1981. It continued to develop various models (on average one new camera model each year) - including product lines such as the Cyber-shot, the 'О±' series and the HandyCam - progressively helping to improve the technology around cameras and photography in general. | TIFF is a computer file format for storing raster graphics images, popular among graphic artists, the publishing industry and photographers. The TIFF format is widely supported by image-manipulation applications, by publishing and page layout applications, and by scanning, faxing, word processing, optical character recognition and other applications. |
| Technical details | ARW files, often referred to as Sony Alpha RAW files, are images digitally captured by Sony cameras and stored in a proprietary RAW uncompressed file. The ARW format is based on the TIFF specification and is a type of RAW (Raw image format) file, containing the metadata that accurately showcases the conditions the shot was captured under. ARW files contain raw, uncompressed image data as captured by the camera's sensors. | A TIFF file, for example, can be a container holding JPEG (lossy) and PackBits (lossless) compressed images. A TIFF file also can include a vector-based clipping path (outlines, croppings, image frames). The ability to store image data in a lossless format makes a TIFF file a useful image archive. |
