The SRW file extension is associated with Sony digital cameras and represents a raw image file format. Raw image files, unlike JPEGs, contain minimally processed data directly from the camera's sensor. This means they retain a significantly higher level of detail and dynamic range compared to compressed image formats. Photographers often prefer SRW files because they offer greater flexibility during post-processing. Adjustments like white balance, exposure, and color correction can be made without the significant loss of quality that occurs when editing JPEG images. SRW files are essentially digital negatives, requiring conversion and processing before they can be viewed or printed. The specific data structure within an SRW file is proprietary to Sony, and while many image editing programs support it, the interpretation and processing algorithms can vary, potentially leading to subtle differences in the final image. The large file size is a trade-off for the increased image quality and editing potential.
