Many camera manufacturers and graphic programs store in the images from additional information in the EXIF format. They include comments, camera model and serial number, copyright, exposure, graphic program, thumbnails or GPS coordinates. This may be for archiving and image analysis very helpful. A Surveying provides the software abylon EXIF CLEANER. In addition, this meta-information is completely removed with one click. By cleaning up the image files your personal fingerprint is removed so no cross-references or tracing is possible. This is useful, for example, if the images on the Internet (pictures archives, communities and social networks) are loaded.
