A user takes a digital photograph with a modern smartphone. The photograph file contains both the image data itself and additional information about the image.
Which of the following is an example of metadata that would be associated with the digital photograph file?
- The total number of pixels that are predominantly blue in the photograph's image.
- The specific time and GPS coordinates where the photograph was taken. (correct answer)
- A compressed version of the image data used for creating a thumbnail preview.
- The names of any individuals identified in the photograph through facial recognition.
Explanation: The correct answer is B. Metadata is data about data. The image itself is the primary data. The time and location where the photo was taken are descriptive pieces of information about the photo file, not part of the visual content itself, making them metadata. The other options describe information derived or extracted from the primary image data, not metadata about the file's creation or properties.
