Raw Image Data (.RAW)
RAW is a general term for unprocessed image data files captured directly from a camera's image sensor, though the .raw extension itself is sometimes used as a generic raw container. Different camera manufacturers use various proprietary raw formats, but files labeled .raw contain minimally processed sensor data preserving maximum detail and dynamic range. These files require specialized software to develop into viewable images.
