What is a .arw file?

ARW files are raw image files created by Sony digital cameras. They contain minimally processed data directly from the camera's sensor. This means that the ARW file retains all the original information captured by the camera, including details about the exposure settings, white balance, and other camera settings. Unlike JPEG files, which are compressed and processed by the camera, ARW files are uncompressed and unprocessed, offering photographers greater flexibility in post-processing. This allows for more precise adjustments to color, exposure, and other parameters without sacrificing image quality. Because ARW files contain so much data, they are typically larger than JPEG files. They are often used by professional photographers and serious amateurs who want to have maximum control over the final look of their images. ARW files need to be processed using specialized software to be viewed and edited, as standard image viewers may not support the format. The post-processing workflow typically involves adjusting the image parameters and then exporting the image to a more widely compatible format like JPEG or TIFF.
