Metadata can be described as information about the data such as file size, date created, file type, etc. ![]() It is platform independent, available as a perl library as well as a command line application. Using exiftool it appears the photos did have their adjusted timestamp written but not to all fields. ExifTool is a free and open source software program which is used to read, write and update metadata of various types of files such as PDF, Audio, Video and images. So whatâs going on?
