What is a .ARW file?
ARW is a raw image file format used by Sony cameras. It contains minimally processed data from the camera's sensor, allowing photographers to adjust settings like exposure and white balance in post-processing.
Background
The ARW file format is used by Sony digital cameras to store raw image data. This format preserves the maximum amount of information captured by the camera's sensor, providing photographers with greater flexibility in post-processing. ARW files are similar to other raw formats like Canon's CR2 or Nikon's NEF, but they are specifically tailored for Sony cameras. Photographers often prefer raw formats like ARW because they allow for non-destructive editing, meaning changes can be made without permanently altering the original image data. This is particularly useful for professional photographers who need to maintain high image quality for printing or publication. ARW files can be quite large due to the amount of data they contain, which may require significant storage space and processing power.
