.ARW File Extension
File Type 1Sony Digital Camera Image
What is an ARW file?
Digital photograph captured by a Sony digital camera, and based on the TIFF specification; contains raw, uncompressed image data as captured by the camera's CCD; can be adjusted using image-editing software before exporting to common raster formats such as .JPG or .TIFF.
Different Sony camera models may store RAWs using the same ".arw" file extension, but with a different format. This is because the CCD on one camera model may differ from the CCD on another camera. Therefore, you should check the documentation of your photo editing software before assuming that it supports a specific camera model.
NOTE: While Sony Camera A and Sony Camera B may both use the ".arw" extension, they may use a different RAW format.
