Metadata View¶
Metadata are data about the images or files, like technical data of camera setting during shooting, author info, copyrights, keywords, captions, and coordinates of location.
The metadata sidebar is composed of five sub tabs Exif, Makernote, IPTC, XMP, and ExifTool Metadata, as shown in these four tabs, can be modified and enhanced in a number of ways elsewhere:
With the Camera interface.
The Metadata Editor.
The Geolocation tool.
Copying file’s metadata to the database.
For each metadata section, a bar is available on the top of view with:
A menu from the left button to use different levels to display contents through:
No Filter: display all markers.
Photograph: display only more important marker for photograph.
Custom: a customized selection of marker set in configuration dialog (see Settings entry).
A really nice feature is the live search box on the middle end of bar. As you type in a keyword, the metadata on top of it will be successively filtered until you narrow down and what you are looking for. It is a quick way of accessing specific information.
A menu from the right button to export contents:
Copy to clipboard: share text information in memory to copy and paste in other application.
Save to file: save chunk of information in data file.
Print data: export information in PDF file or to your printer.
备注
The metadata view preserve the filter settings depending of the file selected. This allow to compare quickly metadata contents between items to identify the differences.
ExifTool View¶
ExifTool is a free and open-source program for reading, writing, and manipulating image, audio, video, and PDF metadata. It is platform independent as a command-line Perl application. Prior, digiKam use Exiv2 library to handle metadata, but it can use also ExifTool as an alternative to incorporate different types of digital workflows not supported by Exiv2.
ExifTool supports many types of metadata including Exif, IPTC, XMP, JFIF, GeoTIFF, ICC Profile, Photoshop IRB, FlashPix, AFCP and ID3, as well as the manufacturer-specific metadata formats of many digital cameras.
You can review information decoded by ExifTool for the selected image in this sidebar tab. The ExifTool Viewer is purely informational: nothing you do with it will cause any change to the information.
