Here are examples of how you might use metadata attributes in a search:You can use other meta tags if they are important to your site.

For example, when you take a digital photo, information such as the camera model, the aperture, and the focal length are among the many attributes automatically stored in the file as metadata.

Take backups before trying these commands otherwise risk damaging or corrupting files WARNING: Changing tags will modify the files you are working on. Changing a tag is similar to reading a tag. If you need to modify metadata tags assigned to a file, you can do that with exiftool also. Reading Metadata with ExifTool: A Simple ExampleChanging Metadata Tags.

The DICOM standard dictates that the image supports tags like the attending physicianвЂ™s name, procedure date, and exposure length.You can add some custom tags not defined by the DICOM or EXIF standard in exiftool and change many tags but not all. These standards define tag вЂњschemasвЂќ that dictate the tags assigned to specific filesFor example, metadata on an x-ray image taken at a hospital or medical center will follow the DICOM standard. For example, two of these standards are Digital Imaging and Communications in Medicine ( DICOM) and Exchangeable image file format (EXIF). Tag StandardsTags are categorized by standards.

The examples in this section are going to use the picture at this link called TestPic.jpg.Be sure to download the example image in its original size. If youвЂ™re taking pictures from a cell phone, you can find instructions on how to get the image files here.The type of image doesnвЂ™t matter but you will find the most interesting metadata if you take a picture from a cell phone and copy it to your computer. If you have a digital camera, you can use the image files from the camera card.

Running exiftool against an image tells the tool to read the image metadata and return all of the default output.Exiftool, by default, returns all tags it understands. Now run exiftool TestPic.jpg. Run cd ~/Downloads/exiftool_demo to bring you into the folder where the image is located.6. This demo will use Windows 10 and PowerShell.5. The command-line interface will vary depending on the operating system youвЂ™re on. Open up your favorite terminal.
