Guide to Changing Metadata on a Photo: Techniques and Best Practices

Metadata is essential for photographers and content creators, as it not only helps in organizing and finding your photos but also in protecting your intellectual property. This article will guide you through the process of changing photo metadata using various methods, ensuring you stay informed about the different types of metadata and best practices.

Understanding Metadata

Metadata on a photo, often referred to as EXIF data, contains technical information about the image and the equipment used to capture it. This includes the lens information, exposure settings, date and time, and image size. On the other hand, IPTC/XMP metadata includes copyright details, photographer information, image title, description, and keywords.

macOS Preview provides a built-in tool for viewing and editing metadata.

4. Using Command Line Tools

For more advanced users, command-line tools like exiftool can be used to edit metadata.
