bildinformation

Bildinformation, or image information, refers to the data that describes an image and is stored with or alongside the image file. It includes technical details about how the image was captured as well as descriptive and rights-related data used to identify, organize, and manage the image throughout its lifecycle.

Common metadata frameworks include Exif (Exchangeable image file format), which records camera settings, date and time, and sometimes GPS coordinates; IPTC Core and XMP (Extensible Metadata Platform) provide descriptive fields such as title, caption, keywords, author, copyright, and licensing terms. Metadata can be embedded in the image file or stored in sidecar files for RAW formats. Typical fields include title, description, author, date, location geodata, keywords, copyright, usage rights, color profile, resolution, dimensions, camera model, and exposure settings.

Bildinformation supports indexing, searchability, digital asset management, archiving, and rights management. It informs publishing workflows and helps automate attribution and licensing checks. Accessibility considerations relate to accompanying descriptive text and alt attributes in published content, which aid users relying on screen readers. Privacy concerns arise with geolocation data or other sensitive information embedded in metadata, so users may choose to strip or scrub metadata before sharing.

Tools and standards for working with bildinformation include ExifTool, Adobe Lightroom and Photoshop, and various open-source libraries that read, edit, or remove metadata. Accurate and consistent image information improves reuse, provenance, and rights management, while requiring attention to accuracy and privacy.
