Teaching with the feed

JPEG Degradation

Watch an image lose data every time it is saved

A demonstration tool that makes lossy compression visible. Each time a JPEG is re-saved, it loses data. Run the sequence and watch the image degrade. A provocation for a lesson on what platforms do to images in circulation.

Research connection

Opens a lesson on algorithmic image culture: how images are compressed, optimised, and altered in circulation before they reach anyone's feed.
