.EXIF File Extension

Information file that contains metadata about an image captured with a digital camera; may include information such as the camera model, shutter speed, aperture, exposure, ISO, focal length, flash on/off, and other information.

EXIF data is typically contained within the same file as the image data and can often be viewed in image editing programs by selecting "Get Info" when viewing the photo. Therefore, most JPEG images that include EXIF data use the standard .JPG extension. However, EXIF data may also be saved to a separate file with an ".exif" extension.
