View EXIF data of a photo with Photo EXIF viewer. EXIF stands for Exchangeable Image File Format. When you take a photo with your digital camera or phone the camera writes technical information about the capture in the photo file. The information includes the aperture shutter speed ISO flash firing status white balance focal length image dimensions and additional information about the device like its manufacturer model and any other information that the device manufacturer includes. It may also include GPS co-ordinates indicating the geo location of the photo.
