Treballar amb les metadades de la foto al digiKam

Transcrit des de l'article d'en Dmitri Popov, el 22 de febrer de 2011

Dins de cada fotografia digital hi ha ocultes metadades en els formats EXIF, IPTC o XMP, i el digiKam proporciona eines per visualitzar i editar aquesta informació útil.

Per a principiants, entre les característiques de la finestra principal de digiKam hi ha la barra lateral de metadades dedicada per visualitzar les metadades EXIF, Makernote, IPTC i XMP. Podeu alternar entre la vista concisa i completa, així com imprimir-les, desar-les com un fitxer, i copiar-les al porta-retalls.

You can use the Caption/Tags sidebar to edit basic metadata such as caption (i.e., the photo’s title), author, date and time as well as assign the photo ratings and tags. The Information section of the sidebar allows you to enter additional information about the photo such as licensing terms, location, and contact info. Since digiKam supports templates, you don’t have to enter this information manually. You can apply an existing template to the photo by selecting it from the Template drop-down list. To create a template on the fly, press the Edit button next to the drop-down list.

digiKam offers metadata editing tools, too. To edit, for example, EXIF metadata, choose Image -> Metadata -> Edit EXIF. The metadata editor conveniently organizes all metadata into sections, making it easier to find and edit specific entries. For example, to edit hardware-related information, switch to the Device section. Here you can modify device manufacturer, device model, exposure-related settings, and other information.

Using the Image -> Metadata -> Import EXIF command, you can copy EXIF metadata from one photo to another. This feature can come in handy when you use an image editing application that strips all metadata from the edited photo. If you keep the original photo, you can easily copy the EXIF metadata from it into the tweaked photo.

Want to strip all EXIF metadata off the photo? digiKam’s got you covered: choose the Image -> Metadata -> Remove EXIF command, and digiKam scrubs the metadata off the photo.

In addition to EXIF, digiKam supports the IPTC and XMP formats, so you can perform the described actions on metadata stored in these formats.

Tip

User comment: I do not edit the metadata that the camera creates but I do add the author/copyright/etc. info using the templates system in digiKam. By selecting multiple images and then using the “dedicated Metadata sidebar” you are able to changes all the images simultaneously. This also applies to tagging images and adding comment metadata.
