It is increasingly easy to manipulate and distribute images. As a result, students need to be able to check whether an image has been manipulated or taken out of context to make their own judgments about the validity of the source and to avoid passing on false stories themselves. This activity provides students with tools to verify the origin of an image and track where it appears on the web. In so doing, it helps students develop their digital competencies in critically assessing the origins of an image and using online tools for exposing metadata and tracking online history.
On completion of this activity, students will:
- Know that all images contain metadata and what that data is.
- Be able to use tools to verify the origin and view the metadata of digital images.
HOW TO DELIVER THIS ACTIVITY
This activity provides students with tools to check image metadata and where that image appears on the internet.
BEFORE THE ACTIVITY
Give presentations on copyright, image manipulation, and integrity. There are some suggestions below under ‘Educator Preparation.’
THE ACTIVITY: STEP BY STEP
After the activity
- Get to know the tools used in the tasks.
- Find online images suitable for the exercise. They must be manipulated and appear in many contexts (found by searching for viral images).
- Familiarise yourself with your institutions rules on applicable copyright and the use of visual materials in academic work.
- Find an image with geodata – also called EXIF. These can be hard to find on Google, but Flickr includes images with EXIF metadata.
