RAW image format
RAW images are "raw" (unprocessed) data captured by the camera's image sensor, and recorded with essentially no loss of image quality from the camera’s internal image processing.
Each camera manufacturer has a different type of RAW format. Therefore, some applications do not support RAW images that have been captured by the camera.
