![]() And if you've never peaked to see what is in there, you should it is fascinating to see all the information hidden inside your digital camera raw file's metadata: exiftool /media/digikam/rawpeg/08/0807/080702_153429.cr2īelow is a tiny excerpt from the terminal output you'd see if you ran the above command (replacing my image file name with your image file name, of course) on one of your digital camera raw files: File Modification Date/Time : 2011:01:20 12:02:35-05:00 The very most basic thing you can do with ExifTool is display your image file metadata. (But then again, I didn't write any of these other softwares, so who am I to complain?) Basic exifTool commands for digital photography As ExifTool was the first and is (imho) by far the most complete, safe, well-tested, well-documented, and up-to-date software you can use to manipulate metadata, I think it is confusing that lesser, later softwares (in the realm of metadata manipulation) don't follow ExifTool's lead in the matter of tag and group names. Warning: ExifTool and digiKam (and other imaging softwares) don't always use the same tag and group names. The list of composite metadata is surprisingly long and comprises some of the most useful metadata you can view, use, and modify at the command line using ExifTool. Composite metadata is constructed for the ExifTool user's convenience, by combining other metadata.XMP metadata is metadata written according to Adobe's XMP standard.IPTC metadata is written to satisfy requirements of the International Press Telecommunications Council's " IPTC Information Interchange Model"). ![]() Your camera also generates proprietary ( but mostly decoded) MakerNotes metadata.Your camera writes EXIF (Exchangeable image file format) metadata, the standards for which are written by JEITA, the Japanese Electronics and Information Technology Indutries Association."File" information isn't metadata that is actually embedded in the image, rather it comes from system information.As you may or may not already know, metadata included in image files comes from several different sources, each of which gets its own ExifTool Group: Each individual bit of metadata information has a "tag name" the tag name lets you know which bit of metadata information you are looking at. If you've ever used digiKam, ExifTool or other software to look at your image metadata, you've noticed that there's a whole lot of it. Tags & groups: Where does image metadata come from? Set the orientation tag to normal for all images in a folder and its subfolders.Copy hierarchical tags written by digiKam or other image organizer from the preview jpeg sidecar files to the corresponding raw files.Copy metadata from the raw file over to the corresponding preview jpeg sidecar.Extract the preview image embedded in raw files.Move or copy image files into folders by year and month. ![]()
